PointSync

This application allows offline point redemption. The point provider issues points and stores the data on the point provider's terminal, the customer reads the QR code displayed by the provider and stores the data on the customer's terminal. The point provider increases or decreases the points for each customer, presents the QR code to the customer, and the customer reads it and stores it in his/her terminal.
You can exchange points using the "PointSync" and "PointSyncLight" apps.
