It exactly meets our needs and want another one now.

I purchased this RFID sticker with the intention of sticking it to the back of my mobile phone. Unfortunately, it was not very good or practical for this purpose. When mobile phone NFC is enabled, such as for tap payments, the sticker becomes useless as it cannot be read. Overall, I wouldn't recommend this product for mobile phone use.

Love it

A great lock with an easy to use interface, no nonsense functionality and quality product.

Perfect. Exactly what I wanted. It’s nice and flat and you barely know it’s there. The sticker seems strong and won’t come off
