A variety of near-field devices, methods and systems are implemented in various fashions. One implementation is directed to a mobile station (102) with an over-the-air (OTA) transceiver (104) for communication with a trusted service manager. The mobile station also has a near-field communications transceiver (112) for communication with a terminal reader using file-identifiers of a first size. A memory (106) is used for storing files arranged according to two different sets of files, the first set of files identified by file-identifiers of a first size and the second set of files identified by file-identifiers of a second size that is a different size from the first size. A processor (108) provides access by the OTA transceiver (104) to the stored files. Access by the near-field communications transceiver (112) is provided to the stored files by running either a Java-based emulator for accessing the first set of files or Java APIs to access the second set of files.
