RFID Help

Hi, Wondering if anyone could help me.

Making a RFID reader to read Livestock tags and display on a screen.

Using this RFID reader - https://www.ebay.co.uk/itm/273984688680

Now currently running tests, using an animal tag Number - ( 704571 00432 ) (Number on the tag)

Once scanned, This should Display on the Screen as - ( 828 704571 00432 ) Tested with another reader and it works.

But currently its displaying - ( 248575648505755448496551514848494849484848481231323 )

Wondering if anyone knew what the problem was? or any advice?

Thankyou

Ask the manufacturer? How would anyone here know the problem? It isn’t an Arduino device and you don’t have the program code for it.
