Frequently asked questions
Can I write a new ID to this card?
Yes. A 125 kHz writer or copier that supports EM4305 can write the ID, so the card can replace a lost card or be used as a blank.
Will it work with a 13.56 MHz reader?
No. EM4305 cards operate at 125 kHz, while 13.56 MHz readers use a different frequency and protocol.
