The group’s planned next step is to release before mid-year a specification for fulfilling its road map. A reference implementation and technology compatibility kit are also in the works and scheduled for a second-quarter release. Devices meeting the JTWI specification should begin reaching the market in late 2003, according to the group.
When it comes to the design of a mobile app, security is its integral aspect. Keeping security in mind, all other programming languages are developed, including the interpreter, compiler, and runtime environment. A lot of concentration is put on testing to ensure potential early errors are caught. The methods for ordering a cup of coffee and requesting a badge to be printed are expected to make a request to the back end, which returns a unique identifier corresponding to the request. Our client application creates a quick response code based on this unique identifier, and then renders the QR code. The demo hardware that was used in the OTN demo areas read this QR code, and sent it to the back end to determine the details about the requested service.
Mobile Section Navigation
A combination of multiple devices, hardware, and software should be taken into account.
