Application Identifier (AID) identifies an → application in a → smart card in accordance with ISO/IEC 7816-5. Part of the AID may be registered nationally or internationally, in which case it is reserved for the registered application and is unique worldwide. An AID consists of two data elements: a registered identifier (RID) and a proprietary identifier (PIX).

AIDs are also used in the security policies (see ’Context’ below): applets’ AIDs are related to the selection mechanisms, packages’ AIDs are used in the enforcement of the firewall. Note: although they serve different purposes, they share the same name space.
