The built-in access control card is not enough, it needs to add an access control card, do I need an access control card dedicated to FCARD? Can other ID access cards be replaced?

OK, may I ask which model of our company you bought. Our individual models are designated encrypted cards, so you can only purchase our cards, most of the access control devices support ID cards on the market. You can buy them outside and issue the cards yourself. But it is recommended to purchase with our company's sales department, the cards we provide are from the largest card factory in China, and the quality is guaranteed.
