13.56MHz RFID/NFC Clear Tag - NTAG203 Chip

This is a transparent 13.56MHz RFID/NFC tag featuring an NTAG203 chip. It's commonly used for train or bus passes, sharing information, and contactless payments. It can also be used in other systems where a proximity card is needed. The tag has a small RFID chip and an antenna, and it gets power passively from the reader/writer when placed a few inches away. Most 13.56MHz RFID/NFC readers can read these tags, but make sure your reader supports ISO/IEC 14443 Type A cards. The NTAG203 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. Each chip has a permanent 7 - byte serial number for identification. These 'Type 2' tags are compatible with any smartphone. They are more secure than 'Classic 1K' cards and work with most RFID - supported phones, avoiding MiFare's patent issues.

Using this 13.56MHz RFID/NFC tag is easy. First, make sure your reader or writer can support ISO/IEC 14443 Type A cards. Then, place the tag a few inches away from the reader/writer to power it up. To write data, you can use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino. Remember, each tag has a unique 7 - byte serial number that can't be changed. When using it with your smartphone, since it's a 'Type 2' tag, it should work with almost any phone that has RFID support. As for maintenance, keep the tag away from extreme temperatures and moisture. If you need to rewrite data, the tag can handle over 10,000 re - writes, so use it as needed.
