<p>Techniques for CSC detection and selection include generating a radio frequency (RF) field that defines a range of communication for the CSC reader, transmitting a signal in the RF field, and detecting a modulation in the RF field indicating that a first CSC is within the RF field and has responded to the signal. The modulation is inspected for collision, wherein collision occurs if more than one CSC within the RF field responds to the poll signal. After determining that the modulation does not contain a collision, a halt command is transmitted to the first CSC instructing the CSC to only respond to one or more specific commands.</p> |
