4.2.1 Get UID and Type (0x01)
The ‘Get UID and Type’ command takes no arguments. After receiving this command, the RFID A1 Module checks for
any tag presence in the field. If there is no tag in the field, it returns ‘No Tag’ value in the ‘Tag Type Register’. If
there is a tag in the field, it reads its UID and type and writes it to Tag UID and Tag Type registers. The ‘UID Size
Register’ together with the ‘Result Register’ are updated also. This command must always be executed first before
any other command to turn on and initialize the tag. Additionally, this command must be executed after any error
when doing any operations on a tag to reset the tag and to enable it to be able to respond to further command
requests.
