Non-transitory storage medium encoded with computer readable information processing program allowing use of data in storage medium among different application programs, information processing apparatus, information processing system, and method of controlling information processing apparatus

A non-transitory storage medium encoded with a computer readable information processing program, the information processing program causing a computer to function as a reading module which reads data from an information storage medium by establishing near field wireless communication with the information storage medium, a first processing module which executes a first application program generating second data with the use of first data read by the reading module, a writing module which writes the second data into the information storage medium by establishing near field wireless communication with the information storage medium, and a second processing module which executes a second application program different from the first application program with the use of the second data read by the reading module.
