Easy to integrate with Arduino

This is a RDM360 (not to be confused with the lower quality, multi-read RDM3600). Integrates easily with Arduino using a single I/O (2 I/O if you want to use interrupts). Antenna is small but provides detection distance of about 2-3cm with standard tags.

speedy delivery

Speedy delivery and product works great. Unlike other RFID solutions, this works straight from the box with no software setup required.

Great Little No-Frills RFID

I have purchased 15 of these so far and love them. You have to keep in mind that the range is about 1 cm so they are best if the card or fob is swiped very close to the antenna. I use the mated fobs and cards and I never found a repeated code,
