Point Redemption

For users who have not installed the app, points are recorded based on the hash of their phone number. These temporarily issued points must be converted into usable points for redemptions.

The conversion to usable points is achieved by installing the user app. When the wallet owner calls the smart contract’s point payment function using their wallet signature, the calculated points are deducted from the user’s balance.

Once this process is confirmed at the kiosk, the redemption is completed. Note that when a user redeems with points, an additional fee equivalent to 5% of the purchase amount must be paid.
