The applications´s AID. An AID uniquely identifies an application, and consists of an RID (a 5-byte "Registered Application Provider Identifier") and a PIX, which identifies an application by that provider. For example, the RID for PKCS#15 consists of the bytes A0 00 00 00 63, and the PIX is the string "PKCS-15". Thus, the AID of a PKCS#15 application on a smart card is A0 00 00 00 63 50 4B 43 53 2D 31.

The length of the AID in bytes.

A UTF-8 string describing the application.

The application´s full path on the card, starting at the MF.

A description of the application, if available.

If the EF(DIR) file is record-structured, this has the record number in which this application is stored. Otherwise, this is -1.
