ST. PETERSBURG, Fla. (8/20/09)--PSCU Financial Services has launched its CardLock service, which enables cardholders to lock and unlock debit and credit cards. CardLock allows cardholders to control the authorization process for all transactions regardless of whether they are conducted in person, on the Internet or via phone. “We lock our homes and cars to prevent or deter theft, and CardLock works the same way for credit and debit cards,” said Steve Ruwe, PSCU Financial Services chief risk officer. If the card is locked, any attempt to authorize a transaction will be declined and the cardholder will be contacted by PSCU Financial Services’ fraud department. However, recurring transactions arranged with a merchant will be accepted even if the account is locked. CardLock can be used with all debit and credit cards issued by credit unions and processed by PSCU Financial Services. Cardholders can call a toll-free number or visit the CardLock website to lock or unlock their accounts with a four-digit code they have selected. PSCU Financial Services is a credit union service organization based in St. Petersburg, Fla.
