  • Everything seems to be working as shown here but when I scan a tag two additional characters are showing, one before and one after the 12 character id. I’m not terribly familiar with rfid, can anyone explain to me what this is about and/or why the additional characters aren’t shown here? -thanks

No public wish lists :(
