The bot understands plain messages

No need to memorise commands. Type "balance" or "I want to return a voucher" and the bot replies with the answer, plus a button that takes you to the right screen in the Mini App.

Feedback is now a chat thread

Send feedback from the Mini App and read replies in a chat-style thread. Uploaders now get notified when one of their vouchers is reported as not working, with the screenshot and the last 4 barcode digits so you know exactly which voucher was flagged.

Jun 4, 2026

Refunds either way when you report a voucher

If you report a voucher as already used, your coins are safe. You get a replacement when one is available, or a full refund when it isn't. Declining a replacement now gets you a refund too.

The service is free, but servers and AI-powered OCR aren't. Your support helps keep the lights on!
