Visa debuts contactless payments keyring
Visa USA is releasing Micro Tag, a chip-based keyring attachment embedded with its payWave contactless technology that can be used instead of cards to pay for low value purchases.
So if I've read this Finextra item correctly - you just wave the thing over a reader with no questions asked. Is this a mugger's dream? How many low value transactions could someone run up before the thing could be cancelled? Or do you just make sure you
only pre-load a small amount in case it's nicked. In that case how do you know you have enough left on it to make sure you're not humiliated when you try to pay.
Or am I missing something here...
