Just on another note, I *hate* pay wave and the shop assistants etc that think you should have to use it. Particularly the asshats at drive thru maccas etc who take your card and then assume its ok. After a few nasty letters they now hand me the eft machine!
I've not felt comfortable with the paywave since it was done the first time at a macca's drive through. No PIN, signature, nothing. Whats the point in having the security of a PIN number if you're just going to hand your cash over anyway? It is a $100 limit, but thats not very reassuring for me!
I have used it. The first time I did it myself it was an accident. The other 2 or 3 times I planned to use the credit option anyway & it was just convenient. But I really don't like that someone out there could take my card & spend an unlimited amount of $99 a time of my money.

Thankfully, there's never $99 in mine to start with! Don't bother with my paywave, you'd strike out But it is linked to my main account.
