I’m the inventor of the NFC Ring and i can’t believe how impressive it's they have copied the NFC ring product already.. Obviously they've needed to make compromises and this could still be vaporware, I will contact them directly to see what I can sort out. The app doesn’t work with NXP tags so most likely doesn’t work with ANY NFC gadgets. They declare it’s titanium when it isn’t, it’s steel ergo can’t be utterly Nickel (allergy) free.. However at a value level of US $30, it’s actually cheep, there isn't a way I can compete with that. I’ve accomplished something else: I’ve put my company’s RFID tag within the cover of my smartphone. I now use my cellphone (Galaxy S2) to open doorways. I discover the ring too visible. I would favor a RFID tag in my watch wrist band. Sander: You find the ring too seen but your cellphone isn’t?
