Abstract

Certain legacy contactless card readers recognize only applets having a short-form AID. However, the long-form AID applets can allow more functionality and specifically can allow use of multiple software applications within a mobile device. A legacy card reader requests invocation of a software applet based on the short-form AID known to the legacy card reader. A router applet operating on the mobile device receives the request for the short-form AID applet, determines the long-form AID applet corresponding to the short-form AID applet, and routes the request to the long-form AID applet, thereby invoking the long-form AID applet. In this manner, legacy readers that have stored therein only the short-form AID applet can invoke the functionality of the long-form AID applet on the smart card. Additionally, newer readers implementing the long-form AID applet can request directly the long-form AID applet.
