Exhibit 99.1

Stockholders of SCM Microsystems Approve

Proposed Business Combination with Bluehill ID AG

SANTA ANA, Calif. and ISMANING, Germany, December 21, 2009 — SCM Microsystems, Inc. (NASDAQ: SCMM; Prime Standard: SMY), a leading provider of solutions for secure access, secure identity and secure exchange, announced today that its stockholders have approved the issuance of new shares of common stock in connection with SCM’s proposed business combination with Bluehill ID AG (FSE:BUQ), an industrial holding group for investments in the radio frequency identification (RFID)/identification and security industries.

     To effect the business combination, on November 20, 2009, SCM made an offer to acquire all of the issued and outstanding bearer shares in Bluehill ID in exchange for shares of SCM common stock. Shareholders of Bluehill ID who accept and tender their shares in the offer will receive 0.52 shares of SCM common stock for every one bearer share in Bluehill ID. The acceptance period for the voluntaty exchange offer will expire on December 29, 2009 at midnight CET. At SCM’s special meeting held on December 18, 2009, more than 98 percent of the votes cast followed the recommendation of SCM’s Board of Directors in favor of the exchange offer and the issuance of new shares of SCM common stock to the Bluehill ID shareholders.

     “The combination with Bluehill ID offers us entry into the important RFID transponder technology market, strengthens our e-passport and national ID business, and helps us expand into important growth verticals and geographies,” commented Felix Marx, chief executive officer of SCM. “The support of our stockholders demonstrates that they understand the important role that acquisitions play in our growth strategy as we work to build a leadership position in contactless technologies and identity management.”

     The business combination with Bluehill ID is conditioned on at least 75% of the outstanding Bluehill ID shares being tendered to and acquired by SCM in accordance with the terms of the exchange offer, among other conditions, and is expected to close in early 2010.

     “SCM and Bluehill ID are focused on the same markets and technologies. Each company complements the other’s product portfolio, technology, market focus and regional strength,” added Marx. “We expect the new, combined company to accelerate consolidation of the highly fragmented identity market and provide a stronger base for future growth.”
