LockNBlock™

Our banking world is one of convenience, where many transactions are processed using debit cards. While this may eliminate the need to carry cash, it also increases the risk of identity theft, and thus fraudulent activity – debit cards stolen, PIN numbers compromised, unauthorized charges processed.

With LockNBlock you can manage the use of your debit cards at anytime, anywhere. In situations where you feel that your debit card has been compromised, you can lock your debit card or block transactions via your mobile app, mobile web, or on online banking.

LockNBlock makes it easier and faster for members to protect their accounts as they will no longer have to call their credit union or visit a branch to lock their debit card if it’s misplaced. However, if it is lost or stolen please LockNBlock and then let us know.
