Markerra
QR/NFC App Demo
Only for iPhone
Free
iPhone
Markerra is a public demonstration of a technical mobile application for QR and NFC workflows.
Use the app to:
• sign in with Apple or Google;
• review and accept participant rules;
• view a map and activate location only when using the map or validating a scan;
• scan test QR codes or NFC tags;
• handle duplicate scans and technical validation messages;
• track progress across five demo points;
• open a technical completion screen after the route;
• review privacy, open-source licenses, and account deletion information;
• control optional analytics independently from core app functions.
The demo does not provide a real prize, discount, or promotion. Location is not tracked in the background. Optional analytics is off by default and can be withdrawn without losing scans or progress.
Markerra's B2B scope is software development and technical delivery: mobile apps, backend integration, physical QR/NFC support, and aggregated functional and technical reporting. A customer defines and supplies its own objectives, rules, content, locations, communication, distribution, and any benefit. Markerra does not create or operate marketing campaigns, purchase media, target audiences, or report attribution or ROAS.
Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
A fresh neon interface for Markerra: redesigned route, map, and QR/NFC scanning screens, clearer progress and finale views, smooth animations, and better scan status messages (validating, success, out of zone, offline). New built-in QR scanner. Stability fixes and minor improvements.
