Abstract

A radio frequency identification (RFID) reader of an apparatus in an example employs substantially synchronized sampling to obtain a signal from an RFID card notwithstanding employment by the RFID card of any of amplitude shift keying (ASK), frequency shift keying (FSK), or phase shift keying (PSK). The RFID reader decodes the signal notwithstanding the employment by the RFID card of any of ASK, FSK, or PSK.
