Each soil drilling has a unique barcode. For checking-in and checking-out samples, TNO’s staff members use a Bluetooth-based infrared scanner. Step one was to connect this Bluetooth scanner to the app. In order to make the app run smoothly without good Wifi- and VPN-connections, we integrated a number of smart solutions. These additions enable the proper synchronisation of the information between the app and the database, even when the signal coverage is bad.
We aimed to keep the app as straightforward and simple as possible, so that it would be easy and fun to work with for all of TNO’s employees. So, no frustrations resulting from a lack of signal or because countless steps have to be followed before a sample’s check-in or check-out can be properly executed. And by using Google’s material design guidelines, we maximised the app’s user-friendliness. An additional benefit is that the users of the app have on-screen access to the buffer status, status updates, and the status of the scan-tasks from and to the database. In brief: a straightforward app that is crystal clear in its use.
