Mobile app for drivers, which specialise on waste field. App gives a possibility to see the list of orders for pick up; type of waste. Driver can see the point of destination on map, scan documents, use digital signature and many other features.
We have used RNCamera and react-native-amazing-cropper for scanning documents and for giving users the opportunity to crop the photo. When a user crops the photo, the app processed it using react-native-color-matrix-image-filters in order to increase the contrast and make the background darker.
