Abstract: One or more applications are registered, managed, launched and/or downloaded using one or more near field communication (NFC) tags. In one embodiment, a NFC application is launched based on detection of a smart code that is in an NFC tag. The NFC application may be configured to write and/or assign a smart code to one or more tags. Another embodiment is directed to a web portal that may be accessed by the NFC application to download applications for presenting data associated with a tag. The NFC application may launch an application based on device placement in proximity to a NFC tag without user interaction, and also allow for writing and/or associating smart codes to NFC tags. The system and methods may overcome or at least ameliorate memory storage capacity limitations in a tag, and may advantageously reduce time and the need of user interaction when opening an application.
