RFID Write by RDM6300

Hello,
I want to make a project where i can write my RFID card by RDM6300. Can anyone help me by writing the code. This code will help me to rewrite RFID card by RDM6300 module.
Thank You

The RDM6300 is for 125 kHz tags, and you can’t write to them.

Are you sure? I got some blank tags that can be written :slight_smile: but IDK how :frowning:

Well, it was a bit of a generalization, while there are many different 125KHz tags out there I only know of one that you could write to. It was a credit size card and about three times as thick as normal card. I did build a rig that would program them but I can't tell you for two reasons:-

  1. It would breach my non disclosure agreement with the business that I signed when I left.

  2. After this long I have forgotten exactly what I did, as it did involve me in modifying some existing designs from the business.

Also these cards were carried "in stock" by the business so I don't even know where they were obtained from.
