APPENDIX
APPENDIX A: Timing
1. Time values stored in the EEPROM have an accuracy of ± 5 ms.
2. The response times of the asynchronous interface depend on:
•
The amount of data to be read or written,
•
The type and number of transponders supported by the reader,
•
The location of the transponder when the request is made,
•
Any existing local electromagnetic interference,
•
The success of failure of the request.
