This is true outside the banks as well. If you make any purchase exceeding 250 USD (approximating a purchase requiring 10+ 100RMB bills), chances are the store will have one of these machines.

China is also the only country I've found myself in possession of counterfeit currency. Sigh, I guess I should just take the loss of 100 RMB but I keep thinking a little luck in a taxi could keep the system flowing...

Heck, I get scanned in some restaurants these days for 30RMB meals. :)
