Can ID TECH tell me what AIDs, CAPKs, and Terminal Settings I Need to Load into my EMV Reader?


EMV readers must be "initialized" with the proper AIDs, CAPKs, and Terminal settings to work. Together these three things make up what we call an EMV Configuration Profile. Profiles differ depending upon many factors, such as supported card brands, desired terminal settings (for example, Unattended vs Attended), and the country intended for deployment.

We (ID TECH's support team) are often asked how a configuration profile should be set. The required profile is determined from the tests a reader must pass to receive an EMV L3 certification.

When a reader completes an EMV L3 certification with an app, a terminal, and a backend processor, you must discover the required AIDs, CAPKs, and terminal settings. The backend processor must identify the targeted card brands to support. The reader must pass a suite of tests for each card brand. Each test will specify the required AIDs, CAPKs, and terminal settings. 

If you are using a solution that is already EMV L3 certified (like a virtual terminal type solution), the provider will need to tell you what specific reader to use and provide a specific configuration profile.
