Ion Bank is expanding the use of video tellers in its branches a little more than a year after initially deploying this technology.

The $1 billion-asset community bank in Naugatuck, Conn., is adding four additional NCR Corporation interactive video teller units to its Waterbury and Oxford branches. Ion introduced its first NCR Interactive Teller in its Wallingford branch two years ago. The bank currently has a total of six Interactive Teller units.

NCR Interactive Teller lets a bank clerk take remote control of a customer's business transaction through video chat. With Interactive Teller, customers can perform secure transactions without a traditional ATM card. Meanwhile, remote tellers have the ability to provide cash beyond ATM limits and assist in mortgage payments.

Interactive Teller allows Ion to extend its teller service hours to 8 a.m. to 8 p.m. on weekdays and 8 a.m. to 3 p.m. on Saturdays. This is an additional 27 hours of banking services per week, Ion said in a press release on Monday.

"NCR Interactive Teller is changing the way consumers bank and helping our customers meet the needs of the consumer," said Jed Taylor, vice president and general manager of NCR Interactive Services, in the release. "Through assisted-service technology, consumers are banking at times convenient to them while maintaining a personal touch with their bank."
