ABSTRACT:
A system of detecting biometric and non-biometric, standard smart card devices includes a smart card host and smart card device reader, which is operable for receiving an Answer to Reset signal and determining whether the smart card device comprises a biometric or non-biometric, standard smart card device. If a biometric smart card device is detected, the smart card reader is operable for applying power used for standard smart card device operation to a first contact and applying power used by a biometric circuit to a second contact, and if a non-biometric, standard smart card device is detected, applying power only to the first contact.
