I need a Wi-Fi connected Electronic Shelf Label (ESL) the ESL runs on 433 MHz Wi-Fi that can generate display text and a QR code sent from a smartphone to the cloud server to the Electronic Shelf Label. The user may be in i.e. Singapore and the Electronic Shelf Label maybe anywhere in the world.
Therefore I will require
1. Database based on cloud
2. Android APK and at some point an IOS app for the Smartphone
If and only you have experience within this field please respond with a brief outline of the project.
