Techniques to perform applet programming

Abstract

Various embodiments are generally directed to techniques provide applets to transaction card. In embodiments, a transaction card may receive an applet signed with a verification signature. The transaction card may determine whether the verification signature matches one of the verification values stored on the memory, enable the applet including the instructions for execution by the processing circuitry in response to the determination the verification signature matches one of the verification values, and prevent enablement of the applet including the instructions for execution in response to the determination the verification signature does not match any of the verification values.
