Mobile app integrated platform

The mobile app integrated platform scales Visa Token Service (VTS) Host Card Emulation (HCE) issuer wallet adoption with a white label solution. On top of that, traveler APIs have been added to enhance the prepaid cardholder experience while traveling abroad.

Technologies and APIs

Near Field Communication (NFC)/Host Card Emulation (HCE) white label mobile app integrated platform with Visa API’s (Visa Transaction Controls, Visa Merchant Offers Resource Center, Visa Global ATM Locator, and Foreign Exchange Rates) + Visa Host Card Emulation SDK.

Note: An organization can request to become a token service provider by participating in the Visa Ready Tokenization program. Please contact Visa directly by emailing to [email protected] to get more information on Visa's HCE SDK. Visa will provide a program overview and the relevant documents necessary to proceed.

Key Benefits

HST has designed its own VDP gateway (a HUB gateway) to connect issuers. They currently offer two business models SAAS  (Software as a Service) and PAAS (Platform as a Service), which enables the following benefits:

  • Continuous delivery and deployment of large Visa APIs.
  • Easier for a developer to understand.
  • Developer speed and productivity. The Integration Development Environment (IDE) is faster making developers more productive.
  • Better testability - services are smaller and faster to test.
  • Better deployability - services can be deployed independently.
  • Each microservice (VISA API) is relatively a small box that can be transparently enabled.
  • Improved fault isolation.

Best Practices

Microservice architecture

Microservice architecture to isolate each service. Meaning that each module is independent in terms of maintenance and development.

VDP Dashboard management

Each issuer has their dedicated profile and key management repository.

VDP module in their PII Data environment

HST has integrated their VDP module in their PII Data environment, which expedite compliance requirements.

Scrum dedicated team

Dedicated scrum team to build Visa API backlog. On average, HST is adding up to 3 APIs per month.
