Why am I finding out now?

I don't recall any local media running with this story back in October, but apparently NYCE and Canada's Interac signed an agreement whereby Canadians can make debit purchases in the US using their PINs, and vice-versa. I've long wondered why we couldn't buy stuff at Interac terminals in Canada, or why no local banks offered that type of service. Apparently, it now exists. I'll have to check it out. UPDATE: I guess I'm still wondering. I was wrong. Only Canadians can use their debit cards at NYCE terminals. Americans can't use Interac.
