                                                             Fremont, California

(the "COMPANY"), promises to pay to SCM Microsystems, Inc., a Delaware
corporation, (the "HOLDER"), the principal sum of Two Million Five Hundred
Thousand Dollars ($2,500,000). Interest shall accrue from the date of this Note
on the unpaid principal amount at a rate equal to ten percent (10%) per annum,
computed on the basis of the actual number of days elapsed and a year of Three
Hundred Sixty (360) days. This Note is being issued pursuant to that certain
Note and Warrant Purchase Agreement dated of even date herewith. Capitalized
terms used but not defined herein have the meanings assigned thereto in Annex A,
Definitions, attached to the Note and Warrant Purchase Agreement. This Note is
subject to the following terms and conditions.

        THE OBLIGATIONS DUE UNDER THIS NOTE ARE SECURED BY A SECURITY AGREEMENT
AND AN INTELLECTUAL PROPERTY SUPPLEMENT TO THE SECURITY AGREEMENT (COLLECTIVELY,
THE "SECURITY AGREEMENTS") EACH DATED AS OF THE DATE HEREOF AND EXECUTED BY
COMPANY IN FAVOR OF HOLDER. ADDITIONAL RIGHTS OF HOLDER ARE SET FORTH IN THE
SECURITY AGREEMENTS.

        1.      MATURITY. Unless converted as provided in Section 2, this Note
will automatically mature and be due and payable on the earlier of (i) June 30,
1999, or (ii) thirty (30) days after the closing of a Change of Control (the
"MATURITY DATE"). Subject to Section 2 below, interest shall accrue on this Note
but shall not be due and payable until the Maturity Date. Notwithstanding the
foregoing, the entire unpaid principal sum of this Note, together with accrued
and unpaid interest thereon, shall become immediately due and payable in
accordance with the provisions of Section 5 in conjunction with an Event of
Default.

        2.      CONVERSION.

                                                               Dazzle Multimedia
                                             Secured Convertible Promissory Note
                                                                          Page 2

                (a)     OPTIONAL CONVERSION. The Holder has the right, at its
option, at any time, to convert this Note and interest thereon, in accordance
with the provisions of this Section 2 hereof, in whole or in part: (i) into
shares of any class of Company Preferred Stock (other than Series A Preferred
Stock (so long as the Company shall have not issued any additional shares of
Series A Preferred Stock other than pursuant to obligations outstanding on the
date hereof) or Series B Preferred Stock) issued by Company after the date
hereof (each an "EQUITY FINANCING"), or (ii) into shares of Series B Preferred
Stock. The Preferred Stock offered in an Equity Financing and the Series B
Preferred Stock each constitute "EQUITY SECURITIES". The number of shares of
Equity Securities to be issued upon such conversion shall be equal to the
quotient obtained by dividing (i) the portion of this Note plus accrued interest
to be converted by (ii) the "CONVERSION PRICE" of the Equity Securities then in
effect, rounded to the nearest whole share, and in connection with any Equity
Financing (other than in respect of the Series B Preferred Stock), the issuance
of such shares upon such conversion shall be upon the terms and subject to the
conditions applicable to such Equity Financing. If the conversion is into shares
of Series B Preferred Stock, then the initial Conversion Price shall be $2.00
per share of Series B Preferred Stock.(1) If the conversion is into Equity
Securities offered in any Equity Financing, then the initial Conversion Price
shall be the price per share as determined in that financing. The Company shall
give the Holder at least ten (10) days prior written notice of any Equity
Financing.

                (b)     MANDATORY CONVERSION.

                        (i)     QUALIFIED EQUITY FINANCING. A "QUALIFIED EQUITY
FINANCING". is an Equity Financing occurring after the date of this Note that is
consummated prior to the Maturity Date and that results in gross cash proceeds
to the Company of at least Five Million Dollars ($5,000,000). The $5,000,000
raised in the Qualified Equity Financing shall be for cash consideration only
and shall not include any cancellation of the Company Trade Facility or the
Company's Debt, including the amount to be converted under this Note. The
Company shall give the Holder at least ten (10) days prior written notice of the
Qualified Equity Financing.

                        (ii)    CONVERSION UPON QUALIFIED EQUITY FINANCING. This
Note, including interest thereon, shall automatically convert into the Equity
Securities offered in a Qualified Equity Financing.

                        (iii)   CONVERSION UPON EXERCISE OF THE WARRANT. This
Note and the then-outstanding principal amount of the Company Trade Facility,
including interest thereon or in respect thereof, shall be automatically
converted in full into Equity Securities upon the Holder's exercise of the
Warrant and shall be effective immediately prior to the exercise of the Warrant.
The class of Equity Securities into which this Note is to be converted shall be
designated by the Holder, and the

      Note.

                                             Secured Convertible Promissory Note
                                                                          Page 3

Conversion Price in respect of such conversions shall be the Conversion Price
applicable to such class of Equity Securities.

                        (iv)    MECHANICS AND EFFECT OF CONVERSION. The Company
shall give the Holder at least ten (10) days prior written notice of a Equity
Financing and shall indicate in such notice if the Company in good faith
believes that such Equity Financing will constitute a Qualified Equity
Financing. No fractional shares of the Company's capital stock will be issued
upon conversion of this Note. In lieu of any fractional share to which the
Holder would otherwise be entitled, the Company will pay to the Holder in cash
the amount of the unconverted principal and interest balance of this Note that
would otherwise be converted into such fractional share. Upon conversion of this
Note pursuant to this Section 2, the Holder shall surrender this Note, duly
endorsed, at the principal offices of the Company or any transfer agent of the
Company and shall give written notice by registered or certified mail, postage
prepaid, to Company at its principal corporate office, of the election to
convert the same pursuant to this Section 2, and shall state therein the amount
of the unpaid principal amount of this Note to be converted and the name or
names in which the certificate or certificates for shares of Equity Securities
are to be issued. At its expense, the Company will, as soon as practicable
thereafter, issue and deliver to such Holder, at such principal office, a
certificate or certificates for the number of shares to which such Holder is
entitled upon such conversion, together with any other securities and property
to which the Holder is entitled upon such conversion under the terms of this
Note, including a check payable to the holder for any cash amounts payable as
described herein and a replacement Note in respect of that portion of this Note
which is not so converted. Upon conversion of this Note, the Company will be
forever released from all of its obligations and liabilities under this Note
with regard to that portion of the principal amount and accrued interest being
converted including without limitation the obligation to pay such portion of the
principal amount and accrued interest. The conversion shall be deemed to have
been made immediately prior to the close of business on the date of the
surrender of this Note, and the Person or Persons entitled to receive the shares
of Equity Securities upon such conversion shall be treated for all purposes as
the record holder or holders of such Equity Securities as of such date.

        3.      PAYMENT. All payments shall be made in lawful money of the
United States of America at such place as the Holder hereof may from time to
time designate in writing to the Company. Payment shall be credited first to the
accrued interest then due and payable and the remainder applied to principal.
Prepayment of this Note may be made at any time without penalty; provided that
the Company provide the Holder with at least ten (10) days prior written notice
of its intention to prepay the amount under this Note.

        4.      CONVERSION PRICE ADJUSTMENTS.

                (a)     ADJUSTMENTS FOR STOCK SPLITS AND SUBDIVISIONS. In the
event Company should at any time or from time to time after the date of issuance
hereof fix a record date for the

                                             Secured Convertible Promissory Note
                                                                          Page 4

effectuation of a split or subdivision of the outstanding shares of Equity
Securities or the determination of holders of the Equity Securities entitled to
receive a dividend or other distribution payable in additional shares of the
Equity Securities or other securities or rights convertible into, or entitling
the holder thereof to receive directly or indirectly, additional shares of the
Equity Securities (hereinafter referred to as the "EQUITY SECURITIES
EQUIVALENTS") without payment of any consideration by such holder for the
additional shares of the Equity Securities or the Equity Securities Equivalents
(including the additional shares of the Equity Securities issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of this Note shall, upon conversion of the Note, be
appropriately decreased so that the number of shares of the Equity Securities
issuable upon conversion of this Note shall be increased in proportion to such
increase of outstanding shares.

                (b)     ADJUSTMENTS FOR REVERSE STOCK SPLITS. If the number of
shares of the Equity Securities outstanding at any time after the date hereof is
decreased by a combination of the outstanding shares of the Equity Securities,
then, following the record date of such combination, the Conversion Price for
this Note shall, upon conversion of the Note, be appropriately increased so that
the number of shares of the Equity Securities issuable on conversion hereof
shall be decreased in proportion to such decrease in outstanding shares.

                (c)     CONVERSION OR REDEMPTION OF EQUITY SECURITIES. Should
all of the Equity Securities be, or if outstanding would be, at any time prior
to full payment of this Note, redeemed or converted into shares of the Company's
Common Stock in accordance with the Company's Articles of Incorporation, then
this Note shall immediately become convertible into that number of shares of the
Company's Common Stock equal to the number of shares of the Common Stock that
would have been received if this Note had been converted in full and the Equity
Securities received thereupon had been simultaneously converted immediately
prior to such event and the Conversion Price shall be immediately adjusted to
equal the quotient obtained by dividing (x) the aggregate Conversion Price of
the maximum number of shares of Equity Securities into which this Note was
convertible immediately prior to such conversion or redemption, by (y) the
number of shares of Common Stock for which this Note is convertible immediately
after such conversion or redemption.

                (d)     NOTICES OF RECORD DATE, ETC. In the event of:

                        (i)     Any taking by the Company of a record of the
holders of any class of securities of the Company for the purpose of determining
the holders thereof who are entitled to receive any dividend (other than a cash
dividend payable out of earned surplus at the same rate as that of the last such
cash dividend theretofore paid) or other distribution or any right to subscribe
for, purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right; or

                        (ii)    Any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
transfer of all or substantially all of the assets of the Company to any other
Person or any consolidation or merger involving the Company; or

                        (iii)   Any voluntary or involuntary dissolution,
liquidation or winding-up of the Company, the Company will mail to the Holder of
this Note at least ten (10) days prior to the earliest date specified therein, a
notice specifying (A) the date on which any such record is to be taken for the
purpose of such dividend, distribution or right and the amount and character of
such dividend, distribution or right; and (B) the date on which any such
reorganization, reclassification, transfer, consolidation, merger, dissolution,
liquidation or winding-up is expected to become effective and the record date
for determining shareholders entitled to vote thereon.

and Warrant Purchase Agreement regarding the reservation of sufficient capital
stock in connection with the conversion of this Note and the Company Trade
