For the next 6 months, you’re probably correct. However, I think after that Target will have the most secure paypoints in the United States. If not, they deserve to go out of business.
That situation with Target did not affect Target Canada, because Canada’s banking system makes it very difficult for things like that to happen. Canada’s financial sector is probably close to the most secure in the world. When there is a breach of somebody’s bank account, in Canada, it’s usually due to carelessness of the individual, not because they breached the bank’s firewalls.
It didn't happen to Target in Canada because they use a different POS system in Canada. Target's announced they're going to bring that same POS system here to the US to solve their problems.
If you really want a secure retail and banking system the U.S. would do what Europe did years ago and implement smart chips in their banking & credit cards.
