What is the ISO/IEC 7816-5 Numbering System?
The numbering system provides a means for an application and related services offered by a provider to identify if a given card contains the elements required by its application and related services.
An application identifier (AID) is used to address an application in the card.
If your application is to be offered internationally, you need an international AID. This consists of a Registered Application Provider Identifier (RID), which identifies Application Providers offering international IC card applications, and is issued by the ISO/IEC 7816-5 Registration Authority (TDC Services A/S). This is followed by a Proprietary Application Identifier Extension (PIX) which enables the Application Provider to differentiate between the different international IC card applications offered.
Each Application Provider is only allowed one RID per ISO/IEC 7816-5. It is up to the Application Provider to use the PIX to identify its different applications.
This RID information document should be read prior to submitting your application.
If your organization already has an Issuer Identification Number (IIN), issued according to ISO/IEC 7812, you may use this IIN instead of getting an RID per ISO/IEC 7816-5. In this case, your AID will consist of your IIN followed by ‘FF’ and a Proprietary Application Identifier Extension (PIX) as described above.
