A device that can read/write tags for a Samsung lock

  • I own a samsung door lock and have two NFC rings that I would like to change for two new ones.
    I bought a read/write device that would not do the job wrong frequency is 13.56mhz the correct frequency I know I can change the lock code bur that is difficult as family have fobs
    The contactless ring is my best buy. I wear latex gloves when shopping and ring works never had any problems saves cleaning cards
