Abstract: Magnetic stripe readers are disclosed that are configured to extract information from magnetic media and encrypt part of the extracted information. Embodiments of magnetic stripe readers include measures to resist tampering and inputs to receive unencrypted information from input devices. One embodiment includes a housing containing a magnetic reading head connected to a decoder circuit that is connected to an encryption engine. The magnetic reading head generates a signal indicative of a magnetic field. The decoder circuit is configured to extract data from the output of the magnetic reading head and the encryption engine is configured to encrypt a portion of the extracted data and the encryption engine is configured to pass a portion of the extracted data unencrypted.

Abstract: A system is disclosed for processing and/or issuing cards containing machine-readable information. The system is preferably housed in a terminal which includes an insertion port to accept a card from a user. The system further includes a hopper which stores a plurality of blank cards. In one embodiment, the hopper and insertion port both lead to a card flipping device, which receives a card and may rotate and/or advance the card to either a card printing module or a card reading/writing module. The card flipping device may rotate through 180°, so that both sides of the card may be printed at the printing module and/or processed in the card reading/writing module. In another embodiment, the system is adapted to receive a personal identification number (PIN) entered directly by a user, and generate corresponding “offsets” or coded inputs for storage on the card.
