Scanning Loyalty Cards at POS
This guide explains how to use the loyalty card scanner on Shopify POS to identify customers during a sale.
How to Scan
Section titled “How to Scan”- On the POS home screen, tap the “Scan Loyalty Card” tile.
- The camera opens with the prompt: “Point camera at customer’s loyalty card QR code”.
- Hold the device steady about 6 inches from the customer’s phone screen.
- Once the QR code is read, the system verifies the card.
- On success, a green banner confirms “Customer added to cart” and the customer is automatically attached to the current sale.
What You See After a Successful Scan
Section titled “What You See After a Successful Scan”- Green banner at the top: “Customer added to cart”
- Customer name displayed below
- Two buttons:
- “Continue sale” — close the scanner and return to the sale
- “Scan another” — scan a different customer’s card
Error Messages
Section titled “Error Messages”If something goes wrong, a red banner appears with one of these messages:
| Message | What It Means |
|---|---|
| ”This card has expired.” | The QR code is past its expiration date. |
| ”This card has been revoked.” | The card was deactivated by an admin. |
| ”Invalid card.” | The QR code is not recognized (damaged, wrong app, or not a loyalty card). |
| ”Verification failed” | Network issue — check your internet connection and try again. |
After any error, tap “Scan again” to retry.
- Hold the device steady and keep the QR code fully in frame.
- Works in most lighting conditions. If the camera struggles, try reducing glare on the customer’s phone screen.
- The customer should have their wallet card open with the QR code visible before you start scanning.
- Each scan automatically links the customer to the current sale — no need to search for them manually.
Troubleshooting
Section titled “Troubleshooting”| Problem | Solution |
|---|---|
| ”Scan Loyalty Card” tile not on POS home screen | Ask your store admin to add the SleekPass tile in POS settings. |
| Camera does not open | Check that the Shopify POS app has camera permission in your device settings. |
| Scan keeps failing with “Invalid” | Confirm the customer is showing a SleekPass loyalty QR code, not a different QR code. |
| ”Expired” error | The customer needs to re-enroll for a new card. Direct them to the store’s sign-up link. |
| Scanner is slow or unresponsive | Close and reopen the scanner by tapping “Scan Loyalty Card” again. |
