Sprint Nextel Corp. will expand availability of Electronic Payment Exchange's payment processing platform to kiosk and self-service station operators under a new agreement between the companies.

Operators of devices such as parking meters, vending machines and sales kiosks that use Sprint 3G's network to transmit data will be able to use Electronic Payment Exchange's tokenization and encryption technology as well as its payments platform.

The agreement extends a relationship that Sprint has had with Wilmington, Del.-based Electronic Payment Exchange since 2009 to allow payments at DVD rental kiosks.

"Businesses today increasingly need to provide payment options for their customers wherever they happen to be, such as a field office or a retail kiosk," Wayne Ward, a vice president at Sprint, said in a press release on Wednesday.

Steven Kendus, Electronic Payment Exchange's marketing director, said in the release that more merchants are using self-service devices.

"The combination of fast, reliable wireless communications and secure payment solutions is a must have for any unattended hardware devices that accept credit cards or debit cards," Kendus said.
