The Task
The challenge was to replicate the functionality of the existing system, but to use modern hardware and software. Rollout needed to be completed before the small number of existing hardware devices became non functional.
Solution
Limitless Solutions partnered with consulting company, Spargonet, to completely rebuild the existing stock control application. Development was completed using C#, Xamarin Forms and, and Zebra hardware devices based on the android operating system. These devices featured laser barcode scanners built in, and connection to bluetooth printers for docket and receipt printing. The advantage of this hardware was that it was effectively a mobile phone, and so was able to be programmed in the same way as any other cross platform mobile device. Limitless Solutions used local storage via SQLite and Azure Rest endpoints for connection to store databases. We also built additional software for diagnosing problems for each device and uploading results. This saved costly on site calls by technical staff to determine issues with hardware.
