Upon successful login, tap the Scan button.
2. This initiates the scan process by opening the camera of your mobile device. If this is the first time, the scanner app will ask you to allow permission to access your device camera.
3. You can also click on the search button and enter the customer’s information. You can search customers by Name, Phone number, Email, and Card Serial Number.
### Transaction by discount card. Upon successful scan, the discount card is displayed in the scanner app. Here, enter the amount you want to add in the Fill in the purchase amount field. Once added, click the Add Points button.
4. A confirmation window will appear. Double-check the amount , and if needed, you can add a comment (this won’t be visible to the client). Then click the 'Add' button and confirm the transaction.
To complete the transaction, click "done". This completes the transaction. ✅ Please note: the scanner always displays the current customer card information and the customer information (the one the customer specified when installing the card). This information can be found on the scanner screen, just below the transaction buttons. It includes customer information (for example, the information they specified when installing their card), as well as card information such as the current discount level, the amount spent, the date the card was installed, the date of the last charge, and more. The exact information displayed may vary depending on the card type.
