Techniques for mobile devices configured to support or function as multiple contactless cards, such as Mifare contactless cards, are disclosed. According to one embodiment, a mobile device embedded with an emulator is loaded with a plurality of software modules or applications, each emulating one card or one type of contactless cards. An emulator is implemented in a secure element that is personalized for a user of the mobile device while the applications are respectively provisioned via their respective providers per the personalized secure element. When the mobile device is to be used as a contactless card to perform a monetary function, a corresponding application is loaded into and executed in the emulator. When the mobile device is to be used to perform another monetary function, a corresponding application is loaded into the emulator to replace the previous application entirely or partially in the emulator. As a result, the mobile device can be used as a monetary device in lieu of multiple contactless cards.
