RFID Readers and RFID tags are a super fun technology to use in your DIY and education projects. With the explosion in Arduino popularity adding an Arduino RFID Shield to your projects can easily add wireless tagging of objects and IDs. RFID stands for Radio Frequency Identification. Each RFID tag has a unique ID which can be read wirelessly from your RFID Reader. Using an RFID reader and tags acting as electronic keys you can create programs to unlock doors or custom project boxes, trigger sounds, photos, or audio files to create games and learning tools, or build custom logging programs for things like races or timecards. Review the different RFID readers and tags offered below to find the right fit for your wireless RFID project.
