These are all excellent, very small and easily detected at a decent range. I can't say enough good things about this supplier, we had a long chat about these before I ordered as this is the first time I've used RFID tech. They were very helpful and guided me perfectly. Shipping was then ultra fast.

Awesome product! We needed a cool and interesting way to invite our customers to leave a review of our service and this was the correct choice! The cards look great, work perfectly and our customers loved them! Special thanks to Heman, who helped us through every step of the purchase and is always there for everything we need. Couldn't be happier with this product!
