The hesitance from some retailers to deploy Paywave/Paypass is that it will increase credit card payments vs eftpos payments which in turn will drive up merchant costs. This is the reason McDonalds in NZ were the first retailer to deploy contactless as part of the ANZ trial before the 2011 World Cup and then proceeded to disable it.
Thats a strange thing that I see people do, they have a credit card, the place accepts them but they still use their ATM card and eftpos things. Im the opposite and use my CC places that even dont say they accept it and then make a big deal that its a hassle when I have to use my other card instead.
