It would seem NFC would require merchants to purchase new registers and POS equipment.

Look at how we're still using magnetic stripes in credit cards because merchants didn't want to buy chip reading POS equipment.

So are they going to change now and incur a new expense because people want to tap their phones?

I thought using cell phone to pay was a curiosity limited to Japan and some Scandinavian countries? Is there any evidence it's expanding.

I wouldn't mind if it caught on tho, better than carrying all these cards (but not necessarily more secure). Only thing is, they should make these NFC implementations interoperable with existing chip-based cards and readers used in many other parts of the world.

I would like for instance to be able to be able to use automated gas stations or Velib in Paris.
