NFC reading App

I manage a network of food-display chillers in the field and will be affixing a unique NFC tag to every unit. I now need a simple, reliable mobile app that my sales reps can carry on their phones. With one tap on the tag the app must:

• read the chiller’s NFC ID
• stamp the salesperson’s identity and a precise timestamp
• capture the phone’s current GPS location

The record should sync immediately (or queue offline and auto-push when data returns) to a cloud-hosted management portal. Inside that portal I want to monitor only sales performance in the form of salesperson activity—specifically the number of visits each chiller receives and where those visits occurred. A quick dashboard view, date and rep filters, and CSV export will cover my reporting needs.

Core deliverables
• Android (and ideally iOS) app capable of NFC read, background location grab, and secure data transfer
• Web portal with login, chiller/tag registry, visit counter, map view, basic analytics, and export
• Source code, deployment instructions, and brief user guide

If you have experience with NFC tooling, Flutter/React Native or native stacks, and lightweight dashboards (Firebase, AWS Amplify, similar), let’s discuss timelines and any questions you have about workflow or data structure.
