[LINK] paywave cards

[Kim Holburn]

I just talked to my building society and the paywave card has a limit of $100 per transaction and $200 per day.  They can't or won't change that limit.  It's not possible to get a visa card without paywave or a mastercard without paypass.  I think it's going to have to be the small hole option.
