Turk Indirim shop application. This is to allow the shop owners to validate the card of the customer by scanning the validity of the barcode printed on the back of the card. The app will check the expiry date of the subscription of the card and will inform the owner of the expiry date. This app is a supplementary app for the main app (TurkIndirim) which enables the user to track offers and discounts from the shops. Enjoy.
