Subject: London transport authority acknowledges contactless technology
risk

How many organisations have warned users of their cards about the risks
vs how many have been discovered and reported ?

I was checking the balance on my Oyster card [1] on-line and noticed
this:

Card clash

Keeping your Oyster card in your wallet or purse with other cards could
cause card clash.


This all looks like commonsense to me - and I only visit the capital
occasionally.

Yes but I currently have one holder for all cards - who will pay for the
extra holders I need now?

Can Tfl assure me that I get a red light and not credit the wrong card.

The current system works. How can I keep it?
