Cellular Credit Card Phone Service
Cellular PayPhone Inc. (CPPI)
Invented first specialized cellular phone and value-added system to automate payments by credit card
In 1986, Harris founded CPPI, a cellular reseller, and obtained two patents for methods to create a complete credit card service. Combining these methods with an application management system developed by SCI, CPPI offered the first specialized cellular phone and value-added service for frequent cellular credit card payments used by taxis, limousines, ferries, trains, and oil rigs. Both Motorola and Oki Electronics built cellular phones for CPPI that accepted credit card swipes for occasional and transient use. The CPPI offering was sold to GTE Mobilnet in 1988.
