Abstract
A card reader system, method, apparatus, and computer program product are disclosed. The card reader can include a transmitter that modulates a radio frequency carrier with a transmit data signal and a receiver that detects a modulation of the radio frequency carrier by a contactless smartcard. A processor can be coupled to the transmitter and the receiver. The processor can generate the transmit data signal so as to simulate a data exchange according to a protocol of the contactless smartcard. The processor can determine a timing for reading data from or writing data to the contactless smartcard and can discontinue the simulated data exchange based on the timing.
