PayCircle Publishes WSDL Payment Specification 1.0 for Mobile Payment

October 09, 2002.

PayCircle announced today that the PayCircle Payment Web Service Specification 1.0 is now available for public review. The specification contains WSDL sources, XML schema definitions and supporting documents. Supporting use case scenarios for this specification together with the specification is available at:

The expected value of and diversity in the types of goods, content, and services that can be supported and delivered via electronic commerce and m-payment are enormous. Mobile / Electronic commerce, now estimated to generate revenues of 1.96 Billion US$ world wide, is expected to grow to 28.0 Billion US$ within the next five years [1]. PayCircle's focus is to help enable M-Commerce via standard APIs for mobile payment. PayCircle API specifications provide standard payment interfaces for merchants, content and application service provider with the expectation of making payment transaction easier for mobile users, which is essential for future market growth.

"CSG Systems has been actively supporting and promoting the PayCircle approach from the beginning, and the publication of this specification defines a clear path forward", said Malcolm Lewis, Director Mobile Industry, CSG Systems and PayCircle Board member. "It defines a common payment approach for the industry, in addition to the various proprietary systems that exist today. We believe the flexibility offered by an open approach will help accelerate the adoption of electronic commerce, and specifically m-payment."

The PayCircle consortium was formed January 2002 to define standard APIs for mobile payments, regardless of the payment systems used by application or service providers. Currently the large number of incompatible payment systems has hindered the growth and uptake of m-commerce. PayCircle defines open and uniform interfaces based on existing standards.

"We are also quite pleased with our liaison work established between PayCircle and other organizations like Mobile Entertainment Forum (MEF), Radicchio and Infrared Data Association (IrDA), ", said PayCircle President, Hans Wolf. "Our successful collaboration efforts with industry fora will help guarantee alignment with other industry standards, and eliminate the type of confusion and fragmentation seen in the industry over the past several years."
