Overview

The Scanner app is a lightweight web application that lets you and your staff scan customer loyalty cards, process transactions, and manage stamps or points — all from a mobile device. It works like a standalone app on your home screen but runs through your web browser.

You can scan a customer's QR code directly, or search for customers by name, phone number, or card serial number when scanning isn't possible (for example, during a remote transaction).

Note: Perkstar also offers Scanner App Pro (Beta), a separate app available on Growth and Scale plans that supports connected 2D barcode scanners (USB and Bluetooth) for a hands-free experience. Scanner App Pro has all the same features as the standard Scanner App, so there's no need to use both. See Scanner App Pro (Beta) for details. The standard Scanner App described in this article is the default and is available on all plans.

How to access the Scanner app

Option 1: Direct link

Open the Scanner app from your mobile device's browser at app.perkstar.co.uk/scanner-app.

Option 2: From your dashboard

Click your profile icon in the top-right corner of the dashboard.
Click the Scanner App tab.
The Scanner app opens in your browser. You can install it from here or copy the link to send to another device.

How to log in

On the Scanner app login screen, enter your email address.
Enter your password.
Tap Sign In.

Note: You can log in with your main account credentials. If you've created manager accounts, your staff can also log in with their own manager credentials.

After logging in, the Scanner app is added to your home screen. Tap the Scanner App icon anytime to open it.

Using the Scanner app

Scanning a customer's card

Tap the Scan button on the home screen to open the scanner. Point your camera at the customer's QR code or barcode to process their card.

Finding a customer without scanning

If you can't scan a card (for example, the customer doesn't have their phone), you can find them manually:

Tap Search Customers on the home screen.
Type the customer's name, phone number, or card serial number.
Select the customer from the results.
Select the correct card and process the transaction.

You can also enter a card serial number directly on the home screen instead of scanning.

Processing a transaction

After scanning or finding a customer, you can add stamps, credit points, deduct visits, enter a purchase amount, or redeem rewards — depending on the card type.

Scanner app settings

Tap the three-line menu icon in the top-right corner, then tap Settings to configure how the app behaves when scanning:

Beep – Plays a sound when a card is scanned
Show results – Displays a notification with the card serial number after scanning
Copy QR code to clipboard – Automatically copies the card serial number after scanning
Debug mode – Shows error details in the app (we recommend keeping this off unless troubleshooting)

FAQs

Can my staff use the Scanner app?

Yes. Create manager accounts in your dashboard and share their login credentials. Each manager can log in to the Scanner app independently with their own email and password.

Can I find a customer without scanning their card?

Yes. Tap Search Customers and search by name, phone number, or card serial number. This is useful for remote transactions or when a customer doesn't have their phone.

Does the Scanner app need to be downloaded from an app store?

No. The Scanner app is a Progressive Web App (PWA) that runs in your browser and can be installed on your home screen. No app store download is required.
