NBTA Credit Union is pleased to be one of the first financial institutions in Canada to offer their Members the ability to control their own debit card security 24/7. You now have the ability to “lock and block” your own card in real time via the NBTA Credit Union App, MemberDirect Online, or MemberDirect Mobile (responsive). This investment in security as well as convenience will allow you to block international transactions (where most debit fraud is happening), immediately lock a misplaced card, and a variety of other functions. To learn more about Lock N Block, see our Lock N Block page here.
