contactless for the first time


Well, to Don's disapproval, I used the MasterCard PayPass payment for the first time with my Commonwealth Bank credit card today.

It was a cheap meal at IKEA Restaurant. And the checkout at the Restaurant section has NAB Contactless EFTPOS terminals (like one above) installed. I, decided to use it, for the sack of experimenting.

It was pretty easy, you don't need to swipe or insert your credit card (keeping it not getting scratched from friction), just hold the card and wave in front of the contactless terminal when it is ready. You will then hear a beep sound. The downside of this is that it is limited to $100 (AUD), otherwise you still have to sign or enter the PIN. (Like I have mentioned before, I strongly encourage everybody to sign instead of using PIN. Remember: In Australia, retailers can not force credit card holders to enter PIN and rejecting signature.)

It is without a doubt that the very secured (and secret) Don would not have approved the use of contactless payment. There are there safe guards on MasterCard PayPass and Visa payWave is that it would only activate (charge) once in a short period, so you don't need to worry. In worst case, the card holder can always dispute.

When I first saw the title, I thought you meant contact lenses!!

The only place I've ever seen a contactless credit/debit card reader is at Mobil gas stations, which I never go to as they're prohibitively expensive anyway.
Well, you know I keep my wallet shielded so the signal doesn't get out.

Rev Dr WuYi,
I have been lazy on putting on the contact lenses. Don,
The signal is extremely weak, you know.

I suspect the "signal leakage" thing has been well researched by the card issuers. In the final analysis, recourse with ones bank is still possible if misuse has occurred.
I am a well known Luddite, but I love my cards and the convenience I get from them. I always check my statements, each and every time I get them, and have never had a problem, or wrong post to my accounts. That's after a lot of years of usage.
Cash is a horrible thing!

Well, Don is known for being very secret. This is like the contactless tickets.
Without a doubt, Don is super worried about the RFID technology despite the fact that the chance of a consumer's credit card being hacked for RFID is very slim (following normal usage/care), Don can give you lots of examples how the world's smartest kids (i.e. MIT students) figured out how to hack RFID.

My example was of a real-world attack, where some people at MIT actually compromised the MBTA's contactless pay system. It only takes some easily-obtainable and inexpensive hardware from Radio Shack to decode them.
