Transaction processing via First Data Web Payment Services provides a number of inherent advantages versus traditional methods of connecting to a processor:
Transaction Speed: By eliminating the dial-up time required by dial terminals, Internet-enabled terminals or back-end systems using EFSnet can reduce 8-20 second transaction times down to 2-3 seconds.
Ease of Integration: By adhering to Internet standards such as HTTPS, SOAP, XML, and TCP/IP, merchants can develop EFSnet applications on many different platforms (Unix, Microsoft, Wireless) using a wide variety of development languages and tools. With access to the latest tools and techniques, merchants can complete development of custom EFSnet applications within days rather than the months and weeks typically associated with developing directly to a payment processor.
Lower Costs: By using the Internet for transaction processing, merchants no longer need dedicated lines that are leased soley to connect to a payment processor. Instead, the same Internet connection that is used for everyday business communication can also perform transaction processing through First Data.
Real-time Access: Processing transactions via the Internet also means that real-time management and tracking of transactions can be accomplished with a Web browser through First Data's Merchant Services Web site. Additionally, custom applications can retrieve transaction histories programmatically.
Single-source Provider: First Data enables one-stop shopping, whereby merchant account activation, EFSnet Web services activation, support, and billing are handled by a single company that can support both front and back-end processing.
Seamless Upgrades: As a hosted solution, First Data can add new payment types and features without disrupting service or distributing software to merchant locations. First Data's server-side upgrades avoids the problems that often plague the distributed-code methodology.
