A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGOTM RFID backscatter transponders, SEGOTM RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

A reading apparatus includes a synchronizing signal output unit, a first imaging unit, a second imaging unit, an acquisition unit, and a transmission unit. The synchronizing signal output unit outputs a synchronizing signal. The first imaging unit images a read target at an imaging position from a first direction in synchronism with the synchronizing signal. The second imaging unit images the read target at the imaging position from a second direction in synchronism with the synchronizing signal. The acquisition unit acquires a first image of the read target captured by the first imaging unit in synchronism with the synchronizing signal, and a second image of the read target captured by the second imaging unit in synchronism with the synchronizing signal. The transmission unit correlates the first image and the second image, and transmits the correlated first image and second image.

A payment terminal such as a payment reader may receive and form electrical connections with an electronic transaction card such as an EMV chip card. The payment terminal may provide a clock signal at a rate that exceeds a specified rate for the EMV chip card. The payment terminal may transmit messages to the EMV chip card and monitor receive messages at a data connection. The payment terminal may determine that the clock rate is excessive based on a timeout of a receive message, an error rate of a receive message, or a receive message indicating that one of the transmit messages was not received by the EMV card. The payment terminal may reduce the clock rate to a rate that is below the specified rate for the EMV chip card.
