These tags work well and are very small. I was able to add them into some scale doll accessories I was making. However the range is very limited. Many NFC tags may work 3-4 inches away from a reader, these are more like 3-4mm. You pretty much have to actually touch them to where the NFC points is in your phone which does vary among models. Pros: Smaller design and unusual shape compared to most tags means you can fit them places others might not. Cons: work at very close range only.
