DTA Loyalty

A loyalty and discount app. Users scan a QR barcode at restaurants and retail outlets. This updates an online database with the time of their visit, and this will triggers a reward when sufficient visits have been registered. The reward and permitted frequency of scans is determined by each retailer.
You will need to have installed a barcode reader app on your device before this app will run properly. Barcode Scanner
from ZXing Team is suitable.
