This is a blank 13.56MHz RFID/NFC card equipped with an NTAG203 chip. It's widely used for train or bus passes, sharing information, and contactless payment. You can also find it in other systems that need a proximity card. The card has a small RFID chip and an antenna, and it gets power passively from the reader/writer when placed a few inches away. Almost any 13.56MHz RFID/NFC reader can read these cards, but ensure it supports ISO/IEC 14443 Type A cards, the standard used by NTAG. These chips can store up to 144 bytes of data in writable EEPROM divided into 4 - byte banks and can handle over 10,000 re - writes. You can use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino to read and write data. There's a permanent 7 - byte serial number ID on the chip for tag identification. This 'Type 2' NTAG chipset is usable with any smartphone. It's more secure than 'Classic 1K' cards and works with most RFID - supported phones, avoiding Mifare's patent issues.
Using this 13.56MHz RFID/NFC card is easy. First, make sure your reader or writer supports ISO/IEC 14443 Type A cards. Then, place the card a few inches away from the reader/writer, and it will get powered up passively. You can use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino to write up to 144 bytes of data to the card. Remember, there's a unique 7 - byte serial number on the chip that can't be changed. When using with a smartphone, just hold the card near the phone's NFC area. Keep the card away from strong magnetic fields and sharp objects to avoid damage. Also, don't expose it to extreme temperatures. With proper care, this card can handle over 10,000 re - writes.
