FAQ:

1. Question: Can I directly register these tags to my electronic lock?
Answer: No. These tags are blank tags without pre-programmed card numbers. The electronic locks cannot write or program a blank tag. The electronic locks can read only. They read card numbers from programmed tags and then verify it Pass or not.

2. Question: Why can't I copy my old tags/cards to your tags by a card writer?
Answer: First, make sure that your card is the same RFID frequency of 125KHZ. Not all RFID cards are 125KHZ type. For example, another popular key cards use the frequency of 13.56MHZ, which is also called NFC card or IC card. Cards of different frequencies are incompatible. Second, make sure that your RFID card writer can work for the frequency 125KHZ, and that you set it in the right channel. Some RFID card writers have several working frequencies.

Important Note:
1. These are blank tags without pre-programmed card numbers. You cannot directly add them to RFID locks or use a card reader to read them. 2. Before use, you must first write data(card numbers) into them by a 125KHz RFID card writer.
