Before use, you must first write data(card numbers) into them by a 125KHz RFID card writer. 3. Smart locks cannot write data to cards. They can read cards only. 4. These 125KHZ cards are ID cards. They are not IC cards or NFC cards. They don't work for TTLock or Tuya smart locks which use 13.56MHZ frequency.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.ETEKJOY 10 PCS Writable 125kHz RFID Key Fob Proximity ID Card Token Tag Rewritable T5577 Universal * Note: They are blank RFID tags, no data inside.
