UnionPay IC Card Card specification-aid application identifier

Application Identification Application Identifier;aid
Consists of a registered application that provides a trademark (RID) and a dedicated application identifier extension (PIX)

AID: Uniquely identifies an application, divided into two parts, RID (5 bytes) +pix (up to 11 bytes)

RID: The registration identifier, assigned by the ISO organization, identifies a globally unique application provider, typically assigned to the card organization, such as assigned to the master, for example, to UnionPay, we follow the PBOC specification, assigned to the rid=a000000333

PIX: Extended application identifiers, typically defined by the application provider itself, such as the pix=010101 of our UnionPay-defined debit applications, the pix=010102 of credit applications, the pix=010103 of quasi-credit applications, and the pix=010106 of pure e-cash applications

So we follow the PBoC code, and the common aid is:

A0, the PBOC loan application

A0 the PBOC Credit application

A0, the PBoC's quasi-credit application

A0, the PBoC pure electronic cash application
