Hanson (Mr. Hanson) and James L. Davis (Mr. Davis, and collectively with Mr. Hanson, Messrs. Hanson and Davis), to provide financing to fund the Companys operations. See Note 10 Related Party Transactions. Convertible Term Loan, due December 2016, interest at 10% In December 2013, the Company entered into a loan and security agreement with Trooien Capital, LLC (Trooien Capital, and the Company refers to this note as the Trooien Capital Note) for a principal amount of up to $4 million. Borrowings under the Trooien Capital Note bear interest at 10% and mature in December 2016. Under the agreement, Trooien Capital has the right, but not the obligation, to advance additional amounts up to the $4 million. Trooien Capital has the right to request shares of common stock, rather than cash, as payment for interest. Trooien Capital had two conversion rights under the Trooien Capital Note, the first of which has expired. Under the second conversion right, Trooien Capital has the right, through the maturity date of the note, to convert the principal and accrued interest into common stock at a conversion rate equal to 125% of the price at which the common stock was sold in the Companys July 2014 initial public offering. Under the terms of this conversion agreement, Trooien Capital will receive 100% warrant coverage. On or about May 24, 2016, Trooien Capital commenced legal action against the Company. See Note 6 Commitments and Contingencies. Convertible Notes, due 2016 and 2017, interest at 0% For accounting purposes, the Company accounts for the debt, warrants and conversion features of the following convertible notes using an allocation process. As a result, the reported amount of the debt has been reduced and will be accreted to face value through each of the maturity dates. Convertible notes that will convert upon listing During the nine months ended September 30, 2016, the Company issued to several investors convertible notes, which are unsecured and do not bear any interest. Each of the investors may elect to convert the principal amount of the notes into shares of the Companys common stock at any time before the maturity date of the notes at a conversion price equal to the lower of $5.55 and 80% of the per share sale price of the Companys common stock in its next underwritten public offering. The Company has the right to require each of the investors to convert the notes into shares of its common stock at that conversion price if the Companys common stock is listed on the Nasdaq Capital Market, the Nasdaq Global Market or the Nasdaq Global Select Market. In addition, under the Companys agreement with each of the investors, it is required to file with the SEC a registration statement covering the resale of the shares of its common stock issuable under the notes and the warrants within 21 days after the offering, or 90 days following the date on which the Companys current financing plan is terminated. If the Company fails to file a registration statement in a timely manner, the Company will be required to issue to each of the investors additional warrants to purchase shares of its common stock. The following table provides additional information about each financing.

Each tranche funded under a note is due and payable in full six months after the date of funding. The first tranche is due on December 9, 2016. In addition to providing three days advance written notice to the June 9, 2016 Investors, under the terms of each note upon repayment of the note (including on the maturity date), the Company is obligated to pay a 20% premium on the then outstanding principal and any accrued default interest then due on the note, which in the aggregate is equal to 120% of the then outstanding principal and any accrued default interest then due on the note. Series Subordinated Note, due January 2016, interest at 12% The series subordinated note was due in January 2016. As of September 30, 2016, the Company has not repaid the note. On March 31, 2016, the holder of the note commenced legal action against the Company. See Note 6 Commitments and Contingencies. Notes Payable, due October 2016, interest between 8.25% and 12% In January 2014, the Company assumed notes payable in connection with the reverse merger transaction pursuant to which the Company acquired the Subsidiary. During the nine months ended September 30, 2016, the Company repaid three of the notes for approximately $11,000, including principal and accrued interest. During 2016, the Company also extended the maturity date of the remaining notes to August 2016 and then to October 2016. As of the date that these financial statements were available to be issued, the Company has not yet repaid these notes but is actively negotiating with the lender to further extend the maturity date of the notes. Note Payable, due August 2021, interest at 0% In August 2014, the Company entered into a 0% interest, $192,000 note payable to the State of Minnesota as part of an angel loan program fund. There are no financial loan covenants associated with the loan, which has a maturity date of August 2021. The loan contains a provision whereby if the Company transfers more than a majority of its ownership, the loan becomes immediately due, along with a 30% premium amount of the principal balance. In addition, if the Company is more than 30 days past due on any payments owed under the loan, the interest rate increases to 20% per annum. Installment Note Payable Bank In January 2016, the Company entered into an installment note payable with a bank, replacing a previous note, for a principal amount of approximately $330,000. The company received the net amount between the two notes, or approximately $69,000, which was primarily used for working capital purposes. The note bears interest at the prime rate plus 1%, but not less than 5%. The note is due in January 2019. The prime rate of interest was 3.50% as of September 30, 2016 and December 31, 2015. Other Information Regarding Debt Except for the Convertible Notes, Due 2016 and 2017, as a result of either the short term duration or recency of its financings or refinancings, the Company believes that the estimated fair value of its outstanding indebtedness approximates market value. | 6. Financing Arrangements The Company has raised debt through several forms of borrowing including bank loans, loans from directors and other affiliated parties and unaffiliated third party investors. Certain of the debt was issued with warrants that permit the investor to acquire shares of the Company’s common stock at prices as specified in the individual agreements. See Note 12 for additional information regarding conversions of debt and accrued interest into common stock during the years ended December 31, 2015 and 2014. Following is a summary of debt outstanding: As of December 31, 2015 December 31, 2014 Notes Payable to Directors and Affiliates $ 1,748,000 $ 1,350,000 Convertible Term Loan, due December 2016, interest at 10% 2,300,000 2,300,000 Series Subordinated Note, due January 2016, interest at 12% 415,398 613,808 Notes Payable, due the earlier of raising $10 million in proceeds from private placements or January 2016, interest between 8.25% and 12% 74,486 74,486 Note Payable, due August 2021, interest 0% 192,000 192,000 Installment Note Payable – Bank 260,949 252,244 Total 4,990,833 4,782,538 Unamortized discount - (145,835 ) Total debt, net 4,990,833 4,636,703 Less: current maturities 4,798,833 2,070,217 Long-term portion $ 192,000 $ 2,566,486 Future maturities of long-term debt at December 31, 2015 are as follows: 2016 $ 4,798,833 2017 - 2018 - 2019 - 2020 - Thereafter 192,000 $ 4,990,833 Senior Secured Note Payable In October 2012, the Company entered into a Loan and Security Agreement (the “Secured Loan Agreement”) with Michaelson Capital Partners, LLC (the “Senior Secured Lender”) that provides for borrowings of up to $1,500,000. Borrowing under the Secured Loan Agreement is secured by all property of the Company including tangible and intangible property. In addition, the Secured Loan Agreement contained certain negative pledges and restrictions on certain types of transactions and use of loan proceeds. The note is guaranteed by a Company director and the spouse of the director. The loans carried stated interest rates from 10-16%. In the event of default the interest rate increased to 14% - 20%. The Secured Loan Agreement’s stated expiration date was April 23, 2013. Beginning in August 2013, the Company was in default and outstanding borrowings and interest began to accrue at the default rates. In addition, the agreement contained certain covenants, some of which the Company was not in compliance with. The note was amended in February 2013 and an additional $1,000,000 was borrowed. Further, as part of this amendment the lender received a payoff premium of $750,000 which the Company accrued as interest expense in 2013 and paid in 2014. On December 6, 2013, the Company entered into a Forbearance Agreement (the “Forbearance Agreement”) with the Senior Secured Lender. The Forbearance Agreement provided that the Senior Secured Lender would not accelerate repayment of the amounts owing, or enforce its security interests or any other rights, under the Secured Loan Agreement, until March 6, 2014. In March 2014, the Forbearance Agreement was extended to May 12, 2014. In consideration for the extension the Company agreed to issue $1 million of the Company’s common stock, the number of shares to be determined by reference to the lowest per share price in the Company’s then planned public offering of common stock. On July 14, 2014 the Company issued to the Senior Secured Lender 44,445 shares of common stock at $22.50 per share for a total value of $1,000,000. In 2014, the Company recorded interest expense of $1,000,000, related to this extension. On May 1, 2014, the Company entered into an agreement with an investor to draw on the $4 million convertible term loan, due December 2016, described below for an amount sufficient to satisfy their outstanding obligation to the Senior Secured Lender, but not to exceed the loan limit of $4 million, for a maximum borrowing of $3.4 million as of March 31, 2014. On May 19, 2014, the Company entered into a second forbearance agreement with the Senior Secured Lender through May 23, 2014 in return for the Company repaying a total sum of $500,000 on this date. In addition, the Company agreed to reduce the price per share related to the $1.0 million of common stock to 80% of the lowest price per share of common stock issued to any investor in the Company if the stock was not publicly traded on or before July 15, 2014. On May 29, 2014, the Company received an advance totaling $1.950 million under the terms of the convertible term loan and repaid a total of $2.0 million of the outstanding balance to the Senior Secured Lender, leaving a remaining balance of $150,660. On May 30, 2014, the Company entered into an unsecured convertible note payable with the Senior Secured Lender for a total of $150,660. The note bore interest at an annual rate of 10% and the principal and accrued interest were due on or prior to July 31, 2014. Upon a thirty day written notice to the Company from the issuance date, the Senior Secured Lender had an option to convert the note into common stock at 90% of the conversion terms offered in the Convertible Subordinated Notes, due June 2015, described below. In addition, upon conversion of the note, the holder was entitled to receive warrants equal to the number of shares received from the conversion at a price of 125% of the IPO price. In July 2014, the Company repaid the remaining note outstanding of $150,660, along with accrued interest totaling $2,559 which satisfied all remaining obligations to the Senior Secured Lender. The Senior Secured Lender also received a warrant to purchase 5,082 shares of Company common stock at $135.00 per share. The warrant expires in October 2017. Including the value of the warrant at the date of issuance, the effective interest rate on the full $2,500,000 available under the Secured Loan Agreement was 38%. The exercise price of the warrant is subject to downward adjustment in the event of the subsequent sale of common stock or convertible debt at a lower price, as defined, prior to exercise of the warrant. As a result of this provision, the Company determined that the warrant should be accounted for as a liability carried at fair value. In February 2013, the exercise price was adjusted to $43.20 and the number of shares of Company common stock to be acquired was increased to 15,881 based on a qualifying transaction. In July 2014, the Company entered into an agreement to modify the terms of the warrant. Under the new terms, the exercise price was reduced to $18.00 per share which is 80% of the IPO share price and the number of shares of Company common stock to be acquired was increased to 38,114. In connection with the issuance of warrants with an exercise price of $17.25 as part of the PIPE transaction completed in 2015, the Company increased the total number of shares of common stock issuable upon exercise of the warrant issued to the Senior Secured Lender to 49,714 and reduced the exercise price to $13.80 per share. In connection with the reduction in exercise price of the warrants issued as part of the PIPE transaction to $4.94, the Company increased the total number of shares of common stock issuable upon exercise of the warrant issued to the Senior Secured Lender to 175,911 and reduced the exercise price to $3.90 per share. The Company determined the value of the warrant to be $537,000 and $146,000 at December 31, 2015 and 2014, respectively, and both of these amounts were recorded as a liability on the balance sheet as of these dates. The Company also incurred financing costs in conjunction with this transaction aggregating $62,500 that are owed under the same terms as terms as the Secured Loan Agreement. The entire amount was fully amortized as of December 31, 2014. Secured Convertible Notes, due June through August 2014 From June through August 2013, the Company borrowed $770,000 under various secured convertible notes. The notes bore interest at the annual rate of 10% and mature one year from the date of issue. Borrowings under the notes were secured by all property of the Company including tangible and intangible property. In addition, the notes contained certain negative pledges and restrictions on certain types of transactions and use of loan proceeds. Upon completion of certain equity financing transactions as defined in the notes, the outstanding principal and unpaid interest was automatically converted into common stock. The conversion rate per share was equal to 75% of the per share price of the securities offered in the defined financing transaction . Notes Payable to Directors and Affiliates In March 2014, the Company borrowed $1,500,000 from a director to fund the acquisition of Select Mobile Money from DeviceFidelity. (See Note 10) The note had an interest rate equal to 24%, payable monthly commencing April 2014. The Company failed to pay the accrued interest on the note due April 2014. As a result, the interest rate increased to 48% in April 2014 and continued to accrue at this rate until the note and all accrued interest was repaid in full. The principal and any unpaid accrued interest became due on May 15, 2014. In addition, the Company agreed to issue common stock as consideration for the note equal to 12.5% of the principal amount or $187,500, which equaled 5,209 shares using the required share price of $36.00. Because the Company failed to pay the accrued interest due April 2014, the Company owed additional common stock equal to 3.125% of the outstanding principal amount or $46,875, which equaled 1,303 shares on each successive 5th business day for as long as any portion of the principal amount of the loan was outstanding. The Company issued a total of 25,521 shares of common stock in connection with this note and recorded interest expense of $890,624 related to the common stock issued for the year ended December 31, 2014. A total of $1,731,781 of principal and accrued interest was repaid in July 2014. In addition to the $1,500,000 March 2014 note above, the Company also issued a total of $3,690,000 of new notes to three directors during the year ended December 31, 2014. Of this amount, $1,925,000 of the notes bears interest at a rate of 10% and becomes due between February and September of 2015, and $1,500,000 represents a line-of-credit agreement with one director of the Company. The original terms of the line-of-credit agreement provided for a stated interest rate of 10% on the principal amount outstanding. Both the principal and unpaid accrued interest is payable upon the earlier of September 30, 2014 or completion of a public offering of securities. There are no financial covenants with the line-of-credit. Through the second quarter of 2014, the Company had drawn down the entire $1,500,000 under this facility. At the option of the director, all the principal and unpaid accrued interest under the line-of-credit could have been converted upon the completion of an IPO of the Company’s common stock at a 20% discount to the price at which the shares are of the Company’s stock were sold in the offering. The director exercised this conversion right with respect to $500,000 of indebtedness in connection with our July 2014 IPO (see June 24, 2014 Letter Agreement below). The Company entered into three notes with directors totaling $265,000 that were due June 30, 2015 and accrued interest at a rate of 8%. The terms of these notes included a provision whereby all principal and accrued interest automatically converted into the Company’s common stock upon the successful consummation of an IPO. On July 14, 2014, the Company completed an IPO and the conversion price equaled 80% of the per share purchase price at which the Company’s common stock was sold in the IPO. On July 14, 2014, $265,000 of principal and $6,763 of accrued interest converted into 15,098 shares of common stock. On June 17, 2014, the Company entered into a conversion agreement with two directors under which a total of $1,050,000 of principal related to the 10% term notes due between February and March 2015 would automatically convert into common stock upon the completion of an IPO of the Company’s common stock at a 20% discount to the price at which the shares of the Company’s stock were sold in the IPO. These notes were converted into common stock at the time of our IPO. Upon conversion, the two directors also received 100% warrant coverage at a price equal to 125% of the IPO price or $28.13. On June 24, 2014, the Company entered into a letter agreement with two directors under which a total of $900,000 of the principal of the 10% term notes due between February and March 2015 and $500,000 of principal owed under the 10% line-of-credit due September 2014 would automatically convert upon the Company completing an IPO. In addition, the director agreed to amend the repayment terms of the line-of-credit to occur on the earlier of (a) raising an aggregate gross proceeds in one or more financing transactions (other than the IPO) of at least $10 million or (b) July 31, 2015. The conversion terms are the same as described in the conversion agreement dated June 17, 2014 above. On July 14, 2014, the Company completed its IPO resulting in $3,375,000 of principal and $204,134 of accrued interest of short-term notes payable with a stated interest rate of 10% converting into 198,841 shares of the Company’s common stock. In addition, the two directors received five-year warrants to purchase a total of 150,000 shares of the Company’s common stock at an exercise price of 125% of the IPO price or $28.20 per share. Lastly, as part of the letter agreement entered into on June 24, 2014, a director agreed to convert $500,000 of principal related to the $1.5 million line-of-credit outstanding into 27,778 shares of common stock and also received five-year warrants to purchase a total of 22,223 shares of the Company’s common stock at an exercise price of 125% of the IPO price or $28.20 per share. The amount of principal owed under the $1.5 million line-of-credit as of December 31, 2015 and December 31, 2014 was $1,000,000 plus accrued interest as of $171,973 and $71,973, respectively. In February 2016, the Company amended the terms of the line of credit to extend the maturity date to January 31, 2017. The Company also agreed to make interest only payments on June 30, 2016, September 30, 2016 and December 31, 2016. The interest only payments are for interest accrued on the principal balance from February 1, 2016 to date of payment. The outstanding principal and accrued interest balance is due in full on January 31, 2017. As a result of the Company completing its IPO on July 14, 2014, the Company determined there was a beneficial conversion feature related to the $1.0 million outstanding balance of the line-of-credit which totaled $250,000. This amount was recorded as a discount to the debt and is being amortized into interest expense through the maturity date of July 31, 2015. For the fiscal year ended December 31, 2015 and December 31, 2014, the Company recorded interest expense of $145,835 and $104,165, respectively, related to amortization expense associated with the beneficial conversion feature. The unamortized balance of the beneficial conversion feature as of the end of December 31, 2015 and December 31, 2014 was approximately $0 and $146,000, respectively. On July 30, 2014, the Company entered into a financing commitment letter with Messrs. Hanson and Davis to lend the Company up to $2.5 million through December 31, 2014, bearing interest at 10%, and due January 31, 2015, which was later extended to January 31, 2016. The terms provided if any portion of the notes issued under the commitment letter were outstanding beyond January 31, 2015, the default interest rate would be adjusted to 18%. As of December 31, 2014, $350,000 was outstanding. In January 2015, the Company received advancements totaling $350,000. On February 3, 2015, Michael Hanson, one of our directors, converted $250,000 of the amount owed into 217,391 shares of Series B Convertible Preferred Stock (which Series B Convertible Preferred Stock was converted into common stock on February 27, 2015). Also in February 2015, the Company amended the terms of the commitment letter to extend the repayment of the outstanding principal balance owed as of that date of $450,000 to January 31, 2016 at a rate of 10% per annum. As part of the amendment, the directors did not renew the remaining amount available under the original terms of the commitment letter. In June 2015, Michael Hanson converted $102,000 of the amount owed into 1,020 shares of Series C Convertible Preferred Stock and also received a five-year warrant to purchase 15,533 shares of common stock at $7.22 per share (since adjusted to $4.94 per share.) On October 23, 2015, the Company entered into an addendum to the financing commitment letter under which Mr. Hanson agreed to an additional advancement of $250,000. As of December 31, 2015, the total principal and accrued interest amount outstanding to Messrs. Davis and Hanson related to advances under the commitment letter equaled $598,000 and $54,857, respectively. In February 2016, the Company amended the terms of the commitment letter to extend the maturity date to January 31, 2017 and maintain the interest rate at 10%. The Company also agreed to make interest only payments on June 30, 2016, September 30, 2016 and December 31, 2016. The interest-only payments are for interest accrued on the principal balance from February 1, 2016 to date of payment. The outstanding principal and accrued interest balance is due in full on January 31, 2017. In March 2015, the Company issued a total of $400,000 of new demand promissory notes to Messrs. Davis and Hanson. The notes bore interest at a rate of 10% and were due June 30, 2015. In June 2015, the $400,000 of notes were converted into 4,000 shares of Series C Convertible Preferred Stock as part of the Series C preferred offering. Messrs. Davis and Hanson also received five year warrants to purchase 60,911 shares of common stock at $7.22 (since adjusted to $4.94) per share. In December 2015, the Company issued a $150,000 demand promissory note to Mr. Hanson. The note bears an interest rate of 10% and is due June 30, 2016. In February 2016, the Company entered into a thirty-day note payable with James L. Davis for $150,000 and Michael J. Hanson for $75,000. Under the note agreements, in lieu of interest, the Company agreed to issue five-year cashless warrants to purchase 16,667 and 8,334 shares of common stock at $4.94 per share to Messrs. Davis and Hanson, respectively. Additionally, for each 30 days the principal amount is outstanding, the Company will issue the note holders an additional 16,667 and 8,334 warrants, respectively, with the same terms as described above. On March 29, 2016, both notes were amended to change the due dates of the principal amounts owed to January 11 and January 31, 2017, under Messrs. Hanson’s and Davis’ notes, respectively. Messrs. Davis and Hanson will continue to earn the warrants on a 30-day basis until the principal is repaid. Convertible Notes due March 2015 In 2013, the Company borrowed $575,000 under convertible notes. These notes were due March 15, 2015. The notes bore a stated interest rate of 10%. Warrants to purchase 5,834 shares of common stock at $60.00 per share were issued with $350,000 of this debt, resulting in an effective interest rate of 19% on that portion of the borrowing. In May 2014, the Company entered into an amendment with various lenders to modify the terms on $350,000 of these convertible notes to the terms provided under the convertible notes due December 2016. Therefore, prior to the Company’s completion of its IPO on July 14, 2014, the total principal amount outstanding of convertible notes due March 31, 2015 was $225,000. Upon the completion of the Company’s IPO, the total outstanding balance of $225,000 in principal and $15,015 of accrued interest automatically converted into 11,853 shares of common stock. Convertible Term Loan, due December 2016 In December 2013, the Company entered into an agreement to issue convertible notes with Trooien capital, LLC (the “Trooien Capital Note”) in a principal amount of up to $4 million. The proceeds of borrowings under the Notes are expressly to be used to repay amounts owed under the Senior Secured Note Payable. Borrowings under the agreement bear interest at 10% and the note matures in December 2016.
