More info

This tiny NFC/RFID micro label is super small and contains an NTAG203 chip and antenna. It is super small, flexible and an excellent way to tinker with an RFID or NFC device if you are interested in designing your own ring, laptop or any other tiny device with integrated near-field communication.

These can be read by almost any 13.56 MHz RFID/NFC reader, but make sure it can handle ISO/IEC 14443 Type A cards (the standard used by NTAG) as there are a few other coding standards (such as FeLica).

These chips can be written and store up to 144 bytes of data in an writable EEPROM divided into 4 byte banks, and can handle more than 10,000 rewrites. You can use the Adafruit NFC/RFID shield for Arduino to read and write data about the EEPROM inside the label. There is also a permanent 7-byte serial number engraved on the chip that you can use to identify one label from another - the identification number cannot be changed.

They use a NTAG chipset, a type 2 label that can be used with any smartphone. Unlike "Classic 1K" cards (alias MiFare S50s), these tags are more secure and work with almost all RFID-enabled phones since they avoid patent issues with Mifare, which requires an NXP chipset or a license.
