[FAQ]awillson71 asked about 125Khz RFID module - UART

Hello folks. I bought EM4100 tags from Amazon and this 125khz reader works great with them. But, the tags are printed on the outside with a unique code that is not the same as the ID that the reader sees. How to correlate the tag's printed code with the ID seen by the reader? Example: tag printed on plastic"0009429268"and reader sees"000042E1E5"in UART/TTL mode. Thanks!
