The free service sends out e-mail alerts to the customer's address based several user-set criteria, said Wells Fargo. Some of the alerts give customers a way to track unauthorized attempts to access their bank accounts.
"Since most identity fraud is self-detected, [these] alerts provide consumers and small businesses with new online tools to more closely monitor their accounts," said James Van Dyke, an analyst with Javelin Strategy & Research, in a statement.
Among the new alerts is one that notifies customers when their account has been locked after three incorrect log-in attempts. Another sends a message that lists the number of purchases over a certain amount made with the user's credit card.
The e-mail alerts, said Wells Fargo, include the pertinent information, but mask key personal data. Customers may request that alerts be send to up to three different e-mail addresses.
