Earnings Per Share	'
	Note 3 – Earnings Per Share
	Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the sum of the weighted-average number of common shares outstanding and the weighted-average number of potential common shares outstanding. There were no anti-dilutive shares in the nine months ended September 30, 2014 and 2013.
	The calculations of basic and diluted earnings per share are as follows:

Industry Segment Information [Abstract]	'
Industry Segment Information	'
	Note 5 – Industry Segment Information
	The services provided by the Company are classified into two reportable segments: Information Services and Banking Services. Each of these segments provides distinct services that are marketed through different channels. They are managed separately due to their unique service, processing and capital requirements.
	The Information Services segment provides transportation, energy, telecommunication, and environmental invoice processing and payment services to large corporations. The Banking Services segment provides banking services primarily to privately held businesses and churches.
	The Company's accounting policies for segments are the same as those described in the summary of significant accounting policies in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. Management evaluates segment performance based on net income after allocations for corporate expenses and income taxes. Transactions between segments are accounted for at what management believes to be fair value.
	Substantially all revenue originates from, and all long-lived assets are located within, the United States, and no revenue from any customer of any segment exceeds 10% of the Company's consolidated revenue.
	Assets represent actual assets owned by Information Services and Banking Services and there is no allocation methodology used. Segment interest from customers is the actual interest earned on the loans owned by Information Services and Banking Services, respectively.
	Summarized information about the Company's operations in each industry segment is as follows:

1	Loans subject to normal monitoring involve borrowers of acceptable-to-strong credit quality and risk, who have the apparent ability to satisfy their loan obligations.
2	Loans subject to special monitoring possess some credit deficiency or potential weakness which requires a high level of management attention.
Impaired loans consist primarily of nonaccrual loans, loans greater than 90 days past due and still accruing interest and troubled debt restructurings, both performing and nonperforming. Troubled debt restructuring involves the granting of a concession to a borrower experiencing financial difficulty resulting in the modification of terms of the loan, such as changes in payment schedule or interest rate. Management measures impairment in accordance with FASB ASC 310, “Allowance for Credit Losses.” At September 30, 2014 and December 31, 2013, all impaired loans were evaluated based on the fair value of the collateral. The fair value of the collateral is based upon an observable market price or current appraised value and therefore, the Company classifies these assets as nonrecurring Level 3. There were no loans delinquent 90 days or more and still accruing interest at September 30, 2014 and December 31, 2013. There were no loans classified as troubled debt restructuring at September 30, 2014 and December 31, 2013.
There were no foreclosed loans recorded as other real estate owned (included in other assets) as of September 30, 2014, and December 31, 2013.

Commitments and Contingencies	'
	Note 7 – Commitments and Contingencies
	In the normal course of business, the Company is party to activities that contain credit, market and operational risks that are not reflected in whole or in part in the Company's consolidated financial statements. Such activities include traditional off-balance sheet credit-related financial instruments and commitments under operating leases. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. The Company's maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, commercial letters of credit and standby letters of credit is represented by the contractual amounts of those instruments. At September 30, 2014 and December 31, 2013, no amounts have been accrued for any estimated losses for these instruments.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commercial and standby letters of credit are conditional commitments issued by the Company or its subsidiaries to guarantee the performance of a customer to a third party. These off-balance sheet financial instruments generally have fixed expiration dates or other termination clauses and may require payment of a fee. At September 30, 2014, the balance of unused loan commitments, standby and commercial letters of credit were $12,582,000, $11,622,000, and $2,978,000, respectively. Since some of the financial instruments may expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. Commitments to extend credit and letters of credit are subject to the same underwriting standards as those financial instruments included on the consolidated balance sheets. The Company evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of the credit, is based on management's credit evaluation of the borrower. Collateral held varies, but is generally accounts receivable, inventory, residential or income-producing commercial property or equipment. In the event of nonperformance, the Company or its subsidiaries may obtain and liquidate the collateral to recover amounts paid under guarantees on these financial instruments.
	The following table summarizes contractual cash obligations of the Company related to operating lease commitments and time deposits at September 30, 2014:
		Amount of Commitment Expiration per Period
					Less than		3-Jan		5-Mar		Over 5
	(In thousands)		Total		1 Year		Years		Years		Years

	Total	$	90,619	$	72,358	$	13,025	$	3,057	$	2,179
	The Company and its subsidiaries are involved in various pending legal actions and proceedings in which claims for damages are asserted. Management, after discussion with legal counsel, believes the ultimate resolution of these legal actions and proceedings will not have a material effect upon the Company's consolidated financial position or results of operations.

Stock-Based Compensation	'
	Note 8 – Stock-Based Compensation
	The Amended and Restated Omnibus Stock and Performance Compensation Plan (the “Omnibus Plan”) permits the issuance of up to 1,500,000 shares of the Company's common stock in the form of stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units and performance awards. The Company issues shares out of treasury stock for these awards. During the nine months ended September 30, 2014, 22,350 restricted shares and 37,213 SARs were granted under the Omnibus Plan.
	Restricted Stock
	Restricted shares granted prior to April 16, 2013 are amortized to expense over a three-year vesting period. Beginning on April 16, 2013, restricted shares granted to Company employees are amortized to expense over a three-year vesting period whereas restricted shares granted to members of the Board of Directors are amortized to expense over a one-year service period, with the exception of those shares granted in lieu of cash payments for retainer fees which are expensed in the period earned. As of September 30, 2014, the total unrecognized compensation expense related to non-vested restricted shares was $1,462,000, and the related weighted-average period over which it is expected to be recognized is approximately .77 years.
	Following is a summary of the activity of the restricted stock:
			Nine Months Ended

	SARs
	SARs vest over a three-year period, with one-third of the shares vesting and becoming exercisable each year on the anniversary date of the grant, and they expire 10 years from the original grant date. As of September 30, 2014, the total unrecognized compensation expense was $1,013,000, and the related weighted-average period over which it is expected to be recognized is 1.3 years.

	Vested		(89,359	)		$	35.09
	Non-vested at September 30, 2014		124,982			$	45.85
	The Company uses the Black-Scholes pricing model to determine the fair value of the SARs at the date of grant.
	Following are the assumptions used to estimate the per-share fair value of SARs granted:
		Nine Months Ended September 30,
		2014			2013
	Risk-free interest rate	2.38		%		1.29	%
	Expected life	7 yrs.				7 yrs.
	Expected volatility	28.11		%		28.72	%
	Expected dividend yield	1.3		%		1.71	%
	The risk-free interest rate is based on the zero-coupon U.S. Treasury yield for the period equal to the expected life of the SARs at the time of the grant. The expected life was derived using the historical exercise activity. The Company uses historical volatility for a period equal to the expected life of the rights using average monthly closing market prices of the Company's stock as reported on The Nasdaq Global Market. The expected dividend yield is based on the Company's current rate of annual dividends.

Defined Pension Plans	'
	Note 9 – Defined Pension Plans
	The Company has a noncontributory defined-benefit pension plan, which covers most of its employees. The Company accrues and makes contributions designed to fund normal service costs on a current basis using the projected unit credit with service proration method to amortize prior service costs arising from improvements in pension benefits and qualifying service prior to the establishment of the plan over a period of approximately 30 years. Disclosure information is based on a measurement date of December 31 of the corresponding year.
	The following table represents the components of the net periodic pension costs for 2013 and an estimate for 2014:
		Estimated			Actual
	(In thousands)	2014			2013
	Service cost – benefits earned during the year	$	3,003		$	3,452

	Net amortization and deferral		244			1,729
	Net periodic pension cost	$	1,573		$	3,531
	Pension costs recorded to expense were $360,000 and $790,000 for the three-month periods ended September 30, 2014 and 2013, respectively, and totaled $1,180,000 and $2,648,000 for the nine-month periods ended September 30, 2014 and 2013, respectively. Pension costs declined significantly in 2014 due to an increase in the discount rate assumption and the favorable asset return in 2013. The Company made no contribution to the plan during the nine-month period ended September 30, 2014 and is evaluating the amount of additional contributions, if any, in 2014.
	In addition to the above funded benefit plan, the Company has an unfunded supplemental executive retirement plan which covers key executives of the Company. This is a noncontributory plan in which the Company and its subsidiaries make accruals designed to fund normal service costs on a current basis using the same method and criteria as its defined benefit plan.
	The following table represents the components of the net periodic pension costs for 2013 and an estimate for 2014:
			Estimated			Actual

	Note 10 – Income Taxes
	As of September 30, 2014, the Company's unrecognized tax benefits were approximately $1,379,000, of which $983,000 would, if recognized, affect the Company's effective tax rate. As of December 31, 2013, the Company's unrecognized tax benefits were approximately $1,208,000, of which $861,000 would, if recognized, affect the Company's effective tax rate. During the next 12 months, the Company may realize a reduction of its unrecognized tax benefits of approximately $251,000 due to the lapse of federal and state statutes of limitations.
	The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The Company had $67,000 and $41,000 of gross interest accrued as of September 30, 2014 and December 31, 2013, respectively. There were no penalties for unrecognized tax benefits accrued at September 30, 2014 and December 31, 2013.
	The Company is subject to income tax in the U.S. federal jurisdiction and numerous state jurisdictions. U.S. federal income tax returns for tax years 2010 through 2013 remain subject to examination by the Internal Revenue Service. In addition, the Company is subject to state tax examinations for the tax years 2010 through 2013.

	Note 11 – Investment in Securities
	Investment securities available-for-sale are recorded at fair value on a recurring basis. The Company's investment securities available-for-sale are measured at fair value using Level 2 valuations. The market evaluation utilizes several sources which include “observable inputs” rather than “significant unobservable inputs” and therefore fall into the Level 2 category.

	There were 30 securities, or 9% of the total (24 greater than 12 months), in an unrealized loss position as of September 30, 2014. There were 102 securities, or 31% of the total (3 greater than 12 months), in an unrealized loss position as of December 31, 2013. All unrealized losses were reviewed to determine whether the losses were other than temporary. Management believes that all unrealized losses are temporary since they were market driven, and it is more likely than not that the Company will not be required to sell prior to recovery of the amortized basis.
	The amortized cost and fair value of investment securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because borrowers have the right to prepay obligations with or without prepayment penalties.

	The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:
	Cash and Cash Equivalents - The carrying amount approximates fair value.
	Investment in Securities - The fair value is measured on a recurring basis using Level 2 valuations. Refer to Note 11, “Investment in Securities,” for fair value and unrealized gains and losses by investment type.
	Loans - The fair value is estimated using present values of future cash flows discounted at risk-adjusted interest rates for each loan category designated by management and is therefore a Level 3 valuation. Management believes that the risk factor embedded in the interest rates along with the allowance for loan losses result in a fair valuation.
	Impaired loans are valued using the fair value of the collateral which is based upon an observable market price or a current appraised value and therefore, the fair value is a nonrecurring Level 3 valuation.
	Accrued Interest Receivable - The carrying amount approximates fair value.
	Deposits - The fair value of demand deposits, savings deposits and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities and therefore, is a Level 2 valuation. The fair value estimates above do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market or the benefit derived from the customer relationship inherent in existing deposits
	Accounts and Drafts Payable - The carrying amount approximates fair value.
	Accrued Interest - The carrying amount approximates fair value.
	There were no transfers between Levels 1 and 2 of the fair value hierarchy for the nine months ended September 30, 2014 and 2013. No financial instruments are measured using Level 3 inputs for the nine months ended September 30, 2014 and 2013.
