The Core Speedway lap counter is an RFID reader based on the TI S6350 module or the Infinity 166 module. This reader uses 13.56MHz ISO15693 RFID tags for tracking RC cars. Details about the TI S6350 hardware can be found at TI's site here, www.ti.com/rfid/shtml/prod-readers-RI-STU-TRDC.shtml. The software uses the UID of each RFID tag to uniquely identify each car.

The Infinity 166 variety of the Core hardware has been sold oversees most likely because the existing TI S6350 module was not RoHS compliant. The software automatically detects this hardware type and changes the timing for this module. While the TI S6350 based RFID reader can read 100 times a second the Infinity 166 module is slightly slower and can only be polled about 50 times a second.
