In Canada we adopted EMV chip debit cards years ago. It's worth noting that even when you switch to EMV, there is about a 5-year conversion period where vendors have to support older non-EMV cards. This is assuming all banks switch to EMV. Canada only has about 5 major banks and they all did it quickly but only recently are swipe-cards losing support.

Since it will take a while to be 100% chip-and-pin from both investment by banks and adoption by consumers, USA can look forward to debit and credit card breaches for a long time. So they'll have to invest heavily in information security, not just EMV.
