The Express Interface Detailed


The Express Interface is a highly secured, scalable, and reliable payment processing platform providing low cost and high speed transaction processing for card-present (such as retail, auto rental, restaurant, etc.) and card-not-present (ecommerce, mail order, telephone order) merchants.


It provides credit card, debit card, and check authorizations processing via the internet for all card types including Visa, MasterCard, AMEX, Discover, Diners, and JCB. Integrating Express with your software provides merchants end-to-end encryption of cardholder data, the ability to store sensitive data off-site to meet PCI DSS compliance requirements, and comprehensive Web-based reporting on their payment card transactions. As an added benefit, because we develop and support the platform entirely in-house, there are no third parties to chase for support.




From a technical standpoint, Express is a server-side Web service application where all communication takes place over secure HTTPS links to the internet. Communication is handled via XML offering a simple and effective method for handling payment processing via the internet. No distribution of source code or DLLs is required, and any device that can originate an HTTPS connection can utilize payment processing through Express. 


Integrating and certifying POS and/or eCommerce applications to Express is quick and easy. The Express processing platform doesn't require you or your customers to download, run or support additional code.


Express provides credit card, debit card, and check authorization processing via the internet for all card types including Visa, MasterCard, American Express, Discover, Diners, JCB and UnionPay. Businesses can integrate this with their software or other customized applications to handle these types of payments in a safe, secure way.


Express has the versatility to handle additional merchant types. If you do not see what you need, download the attachment and contact Vantiv certification.
