It is not a coincidence, but the Vegas odds would be on the international card authorization service center in Brazil, not Jamaica. All international card transactions in the Caribbean are processed there. It is the regional clearinghouse.
Local cards are not processed through that Brazil center but locally on the island. They are not having this problem. I use my local debit card daily all over the island at ATMs, stores, banks, etc and have seen no problems, nor have anyone I know who use theirs had an issue. But if they use their international cards (Visa/MC/etc), that is when they see it.
It is only when these cards are processed through the Brazil center when the problem occurs. That is one constant in this scam. As some have pointed out, transactions as far have Belgium have taken place after a card was used in the Caribbean. The scammers try to stay one step ahead of the security, which is only as good as the person(s) who designed it.
Keep checking your bank statements and check them online at a secure location - that is always wise advice in this age of almost pure plastic transactions... jamaicajeanne explains it from a banking insiders perspective.
