The text in the title "10pcs/20pcs 125khz control keyfobs rewritable duplicate tag tk4100 proximity copy access card id token ring rfid cloner keychain" is misleading, the tags are read-only and cannot be written. . . At least they work but. . . I can't use them as intended Next time i should read all the description not only the title of the product

The advertisement says it's re-recordable, but it's not. It doesn't accept recording. It's read-only. And it arrived late. I'm returning it.
