Credit unions are going old school by increasing the use of text messaging to keep up with members.

While the feature isn’t new, many U.S. businesses are behind the curve in terms of using short message services, or SMS, to communicate to customers. But that is changing, and credit unions are getting in on the action, largely to confirm members’ identities when they look to log into an account.

“Who wants to get a phone call to remind them that their loan payment is overdue when they could get a text that even includes a link to quickly and efficiently resolve the situation?” said Tom Sheahan, CEO of Red Oxygen, a San Francisco company that provides SMS solutions.
