Hmm, how do I delete above comments, when I leave comment, it was giving errors. I tried some, then they just suddenly appeared.

Sorry for confusing post, my English sucks. Whole e-commerce website is much bigger, sells many things. E-Ticket and Coupons are only small part of it. What this application do is, it scans & confirms only already bought tickets/coupons. It don't sell anything. Just scan and claim button, thats all.

Sorry for confusing post, my English sucks. Our whole website is much bigger, it sells many things. E-ticket and coupon is only small part of it. Then this app only scan qr and if QR is valid, there is button appears, and when it clicked, it consumes current ticket & coupon etc. No other things, don't sell anyhing. So comparing to whole website, its just simple, small thing.
