Lerusin

Lerusin is a simple app for use anywhere that requires paper QR codes.
It allows you to copy QR codes using the device camera, then use your device screen instead of that QR code. Great for anywhere that provides access codes on paper - such as gyms, sports clubs & facilities, book clubs and more.
Once copied, easily display them or scan them from your phone screen. Perfect for hand scanner or turnstile access.
No more carrying paper codes.
No more wear and tear on paper access codes.
No more waiting in queues for a replacement paper codes.
No login or account is required - simply scan QR codes provided on paper or otherwise, rename (and colour) them so you can remember what they're for, then tap to present them full screen for easy scanning.
