Hi Product Hunt, I'm Junayed, and I built Kizmo. Two things kept coming up when I read reviews of QR code services. Businesses print codes on menus and signs, a free trial ends, and every printed code stops working until they pay. And scammers now put fake QR stickers over real ones on parking meters and restaurant tables; the FTC warned about exactly this in September. So Kizmo does two things: 1. Your codes keep redirecting on every plan, even if you cancel. It's in our terms. 2. Kizmo learns how often each code is normally scanned. If a busy code suddenly goes quiet, you get an alert to go and check it, because that's usually a sticker. The generator and the QR safety checker are free with no account. Dynamic codes are free for 3, with no card. I'd love feedback on one thing in particular: what would make you trust a QR code enough to pay with it?
