Scan RFID cards when prototyping systems for item tracking and conveyor sorting. These readers scan one card at a time without requiring a direct line of sight, so they'll work in areas where bar code scanners can't. An LED and a buzzer indicate each successful scan. Readers connect to your development board with an included Qwiic cord that snaps into place, saving you the effort of soldering. If your board doesn’t have a Qwiic connection, choose a cord with a machine-pin plug. The two included RFID cards, as well as additional cards, have unique IDs and cannot be rewritten.

Control circuits with the tap of an RFID tag. Since each tag (sold separately) has a unique digital code, these switches aren’t just quicker to use than those with a traditional key—they’re also more secure. Use them to limit access to sensitive equipment, prevent accidental actuation, and also to keep tabs on access. Unlike standard switches, the RFID reader records data about every signal sent, so you can track exactly who operated these switches and when. They have enough memory to store and manage up to 500 tag codes, which you can rewrite and deactivate as needed.

All fit in a standard panel cutout. To set up these switches, connect them via ethernet cord (sold separately) to a computer, programmable logic controller (PLC), or another controller. No separate RFID writer required.
