Hello, when MC-5848T is swiping a legal card, the card number of the same card is not true and will change constantly, power failure and factory reset are useless, how to deal with this?
Hello, please remove the access control card reader and connect it to the terminal of the control board reader, and then swipe the card to see if the card number of the same card is constantly changing. If it is, it should be a problem with the card reader. if not, it is a problem with the reader's line interference.
