Hey Product Hunt. Plain QR codes are a scam we keep shipping. They are just text. Screenshot once and you have a forever ticket. No signature. No expiry. No single use. That is how fake event tickets, reused attendance QR codes, and leaked coupon links happen. We built AdmitiQ for that. Open source library for signed QR codes and signed URL tokens. Issue with a TTL. Verify signature, expiry, optional single-use. Same token in Python and JavaScript. pip install admitiq npm install admitiq Try without an account: https://admitiq.logiclitz.org/tu...

LogicLitz: https://logiclitz.org If you have ever searched secure QR ticket, expiring QR code, single use QR, or signed ticket token and ended up duct taping JWT plus Redis, this is the boring tool we wanted. Reply with one: 1. Did a screenshotted QR ever burn you? 2. Python, Node, or both? 3. Tickets, attendance, coupons, access, or something else? We are here all day. Break the tutorial and tell us what is missing.
