🔗 GitHub Repository: NativeAppTemplate-Free-Android

I enhanced this open-source repository with comprehensive NFC features, including:

• Writing application info to a tag
• Reading an NFC tag
• Background tag reading

NFC Tag Operations

Overview

The app replaces traditional paper tags with NFC tags to efficiently manage walk-in customer waitlists. It writes application-specific information onto your NFC cards (referred to as 🔴 Server Tag and 🔵 Customer Tag).

For Customers:
When a customer scans a 🔵 Customer Tag, they can view the 🟢 Number Tags Webpage (a public webpage) on their mobile browser. This page displays completed Number Tags.

For Staff:
By scanning a 🔴 Server Tag paired with the 🔵 Customer Tag, staff can complete a Number Tag. Completed Number Tags automatically appear on the 🟢 Number Tags Webpage for customer reference.

How It Works

1. Write application info to pair Number Tags (Server Tag and Customer Tag) or a Customer QR code:
   • Go to: Shops > [Shop] > Shop Settings > Manage Number Tags > [Manage Number Tag].
2. Scan a Server Tag in the Scan tab.
3. View the updated Number Tags status in the Shop Detail screen or on the Number Tags Webpage (see Background Tag Reading GIF below).

Recommended NFC Tags

For best performance, use NTAG215 (540 bytes) tags.
Example: 50pcs NFC Cards Ntag215 (Amazon USA).

Background Tag Reading

1. Scan a Server Tag.
2. View the updated Number Tags status in the Shop Detail screen or on the Number Tags Webpage.
