Hey guys, check out P神's post over at http://www.hongkongcard.com/forum/fo...p?id=12272&p=6 #59 re disarming BOC thermal terminals

I'm in Vietnam this weekend. Not using V/M much but no DCC still

P.S. I've just translated the mainland forum bit:

Some pos terminal, such as Bank of China, after swiping card (I think) displays something like "if not, press the Cancel key ..." message. From the wording alone, you wont know you're being DCCed. If you do nothing in the next 2-3 seconds you will be DCCed. If you don't physically see the pos terminal, you will be DCCed cos there's no further need for input like PIN. Therefore, in this 2-3 seconds, press the cancel key on the pos terminal. The pos may prompt to cancel the transaction - select yes, after which the slip will be DCC free.

A worser type is Bankcomm - you will be DCCed without any opportunity to stop it. bank pos settings are not the same. Under the circumstances, void the slip (after both customer and merchant copies are printed) and see if there are any options to cancel DCC only (on certain Bankcomm terminals this is the third option). If such an option is available and selected, a DCC-free slip will be printed"
