📖 How the System Works

1️⃣ Admin Creates Cards

The administrator creates a card and generates a permanent QR code containing the Card ID.

2️⃣ QR Code Stays the Same

The QR code does not contain the changing balance. It identifies the card, so it does not need to be printed again after every transaction.

3️⃣ Scan to See Balance

When a QR code is scanned, the system identifies the card and displays its current balance.

4️⃣ Transfer Between QR Cards

In QR Transfer mode, the source card is scanned, the amount is entered, and the destination card is scanned. The transfer then updates both balances.
