What are the failure codes of RFID systems in the related software?
How to find the RFID fault code and how to solve the problem
Fault code interpretation is as follows:

- 01: no coding block read/write head area,
- 02: can't run the task, he can't read the code block,
- 03: read coding block removed the read/write head in the process of reading area,
- 04: cannot write coding block,
- 05: written coding block removed the read/write head in the process of writing area,
- 07: AV bits or bytes in size as hex instruction distributor does not exist or is invalid,
- 09: read/write head cable breakage or read/write head not connected,

- 0D: read/write head of the communication interrupt,
- 0F: read data CRC and do not match the CRC code block, bits string of 1 and 2 bits are not equal, so the second bit string must be used.

- 20: the address of read and write tasks is outside the memory range of the encoding block
- 21: this function is not available for the current encoding block.
