## Description

This is a keychain-friendly RFID/NFC tag with an NTAG213 chip. The tag contains a small RFID chip and an antenna, which get passively powered by a nearby reader/writer.

Use these tags to create your own access control system, keep track of tools in your workshop or make a contactless vending machine. These tags can also be programmed with a special code that instructs the reader (eg. smartphone) to open a specific webpage, or navigate to an exact location on a map.

These can be read by almost any 13.56MHz RFID/NFC reader (or NFC enabled mobile-phone), since the NTAG213 standard is open source and avoids licensing issues present in older "Classic" cards (eg. MiFare).
