Just to add some more numbers, in Canada, the maximum is $50 and I've used i=
t for transactions of $5, even less.

I use it every day to pay for breakfast and it works through my wallet, even=
 with multiple NFC enabled cards in there (though not overlapping). The expe=
rience is quite smooth; simply tap my wallet on the POS and a few seconds la=
ter it's approved.
