Library > Using The Library

The Library contains Visa proprietary technical specifications that are used in the development of chip products as follows:

  • Contact/contactless reader/terminals (devices)
  • Contact/contactless chip card products
  • Chip components used in chip cards
  • Operating system and payment application software
  • Personalization systems

The technology that you need depends on:

  • Are you developing cards, chip components or reader/terminals?
  • Is your product contact only, contactless only or both?
  • Where will you be deploying your product, that is, what part of the world? There may be additional requirements based on the region.

Best Practices

  • Review the library categories/content, which indicates the license required, to help you determine the Visa technology you will need to build your product.
  • Before initiating a development project, verify you are using the latest versions of the technology specifications, for example, VIS and VCPS and the applets.
  • Please check with your regional or country Visa representative to determine the specifications and applet versions used in your region as well as any other regional-specific requirements.
  • Check this site regularly for updates to current specifications. Subscribers will receive notifications so make sure your email contact is current.
  • Review the Visa Sunset Plan (Subscriber Only), available under Bulletins and Announcements, to ensure that testing will be available for the product when your development has been completed. Visa will not approve products nor allow them to be deployed in the marketplace without Approval Testing.
