The LASTSCANVALUE returns the last value scanned by the client device and processed by the mobile application. If called prior to a value being scanned in or on a device without scanning capabilities, the function will return an empty string. The last scanned value will be returned regardless of where or when the function is called. Exiting and restarting the mobile application will remove the scanned value, and the function will return null until a new value is scanned.
- This function takes no parameters.
