But other phones have antene in back cover for minimize distance with NFC chip. When Jolla phone is not made this way, i see problem for NFC communication with external NFC tags .. Kaacz -- >From Nokia N9 :)

Yes it can, for some types of tags. Assuming that the tag used by TOH is of a type that supports detecting multiple tags in field or is of a different technology that otherwise does not interfere with the tag being read, then yes this is feasible. > and all the other halves surely have some sort of unique id (so > that different ambiances can be detected) that all have a common prefix > (so that the device can distinguish between OH and another NFC device I'm not completely familiar with the details, that may be true for TOH tag id. It does not prevent collisions with tags in the wild. For example some tags generate a random id on every access.
