A stamp card is a loyalty card that rewards customers for purchases or visits. Customers earn stamps for qualifying actions and redeem a reward after collecting a set number — similar to how Starbucks rewards work, where you collect stars and earn a free coffee.

Customers can see on the card how many stamps they've collected, how many more they need for a reward, and when a reward has been earned. Once the reward is redeemed, you deduct it from the customer's card, and they start collecting stamps again.

You can either create a card using one of 111 pre-loaded templates designed for popular business niches (cafes, car washes, cleaning services, and more) or build one from scratch. This guide walks through creating a card from scratch.

A card is created by completing five sections: Card Type, Settings, Design, Information, and Save & Preview.

Perkstar supports seven loyalty card types: Stamp, Multipass, Discount, Cashback, Coupon, Certificate, and Membership.

Choose the barcode type that determines how the card is scanned and recognized by the system. Select whichever appearance you prefer.

Select how customers will earn stamps:

Important: The system does not support automatic custom rules (like "1 stamp for every 3 visits" or "only if purchase > $20"). Such conditions can only be applied manually.

Tip: If you enable Restrict to 1 check-in per customer per day, customers will receive rewards only once per day, regardless of multiple check-ins.

Important: Reward cost is mandatory when integrating with Toast.

This setting lets you select a time period during which customers earn an increased number of stamps per visit.

Note: Happy hours only works when the stamp is awarded in Spend or Visit mode. This stamp does not have a specific validity period.

Define the number of days a stamp remains valid after it is earned. Options include unlimited, a fixed future date, or a fixed term after the stamp is earned.

Tip: Setting a short expiration (e.g., 7 days) is a powerful way to drive repeat visits. If a customer doesn't return within 7 days, only their last collected stamp is removed — motivating them to come back on a predictable schedule. For example, if you set the validity to 1 month and a customer earns a stamp on April 5th, that stamp will expire and be removed on May 5th.

Enter the location(s) of your business to trigger push messages. Customers who have the card installed in Apple Wallet will receive a push notification when they are within 100 meters. You can add 1 location on the Starter plan, 3 on Growth, and up to 10 on the Scale plan — they don't need to be business addresses.

Tip: Geo-located push notifications are a powerful way to attract nearby customers and increase retention for local businesses.

Select the language for your stamp card from the dropdown menu. Over 30 languages are available.

Choose how the date is displayed on the card. If the card has no expiration date, this setting is irrelevant.

For stamp cards, this setting is irrelevant since this card type has no points. It applies to other card types and defines how the point balance is displayed.

When turned on, this setting requires the purchase amount to be entered whenever a transaction is processed. The amount is counted in ROI statistics under the revenue figure.

Note: This applies only to transactions made via the scanner. If disabled, the purchase amount is optional.

Define the fields you want to include on the stamp card. This is the form customers fill out when installing the card. By default, the form asks for first name, last name, phone, and date of birth.

Important: Do not make fields other than phone number unique. For example, marking "Name" as unique would prevent customers with the same name from installing the card.

To add a new field, click Add field, then select the field type and enter the field name. You can also rename existing fields.

Create channel links for analytics tracking. For example, create separate UTM tags for Facebook, Google Ads, and partner promotions. Perkstar generates a unique URL and QR code for each tag so you can track which distribution channel performs best.

You can create unlimited UTM-tagged links. Track how many customers installed the card via each tag in your statistics.

Select which country prefix appears by default in the card issuance form. Customers can choose a different country if needed.

Enable the toggle to display consent on the card's release form. Customers must accept the condition before installing the card. You can edit the privacy policy text as needed.

Consent to the processing of personal data enables or disables a checkbox that reads "I agree that my personal data can be used and provided for direct marketing purposes." You can customize this text.

When enabled, the Google Wallet button appears on the card installation form, allowing Android users to add their loyalty card to Google Wallet.

When enabled, the PWA (Progressive Web App) button appears on the card installation form. Customers can install the loyalty card as a web app on their devices without needing an app store.

Control how many cards can be distributed. Set to 0 for unlimited.

Control how many stamps a customer can earn in a single day. The daily limit resets at 12:00 AM.

Set the starting number of stamps a customer receives upon getting the card (default is 0). These act as welcome stamps to give customers a head start.

On a customer's birthday, the specified number of additional stamps will be credited to their card. The customer receives a push notification informing them of the increase. This stamp has no specific expiration date.

If you want to include a customized analytics script, add it in the Analytics field.

Once all fields are configured, click Continue to move to the Design section.

Choose the number of stamps required to redeem the reward (from 1 to 30). For example, setting 15 stamps means customers need to collect 15 stamps to earn their reward.

Important: This setting cannot be changed after the card has been activated. Stamp positions are fixed and depend on the number of stamps selected.

Important: You must use the same method (icon or image) for both active and inactive stamps.

Click Select File to upload a logo displayed on the card and the release form.

Click Select File to upload an icon displayed in push messages next to your company name.

Click Select File to upload a background image for the stamp area. It can be a themed picture. Minimum file size is 1125 x 432 pixels.

Tip: Follow the file size and weight recommendations for best results.

Set colors for card background, text color, stamp background, outline color, active stamp, inactive stamp, and background under stamps.

Note: If you uploaded custom files for stamps and the background, you can skip this setting. Colors only apply to system icons from the dropdown list.

Use the Field dropdown to select a field type, then rename it in the Field Name column. For example, you can rename "name" to "cardholder." Default fields include stamps until reward and count of available rewards. You can also display personal data fields from the card issuing form (first name, last name, phone, email).

Once all design choices are made, click Continue to move to the Information section.

Enter a short description of the card — this is the name of your promotion.

Define how a customer earns a stamp (e.g., "Buy anything to get a stamp"). This text explains the earning criteria to customers.

Enter the name of your business.

Describe the reward (e.g., "6 stamps = free coffee"). This text appears on the back of the card and in PDF promotional material.

Enter the message displayed when a customer earns a stamp. This is sent as a transactional push notification. Be sure to keep the hash sign symbol — it will be replaced with the actual remaining stamp count.

Enter the message displayed when a customer earns a reward. This is also sent as a push notification.

Tip: Adding images to your reward messages works as an eye-opener and gets additional attention from customers.

Enter stamp numbers separated by commas (e.g., 3,6,9) to offer rewards at specific milestones. When a customer reaches a milestone, they unlock a reward and can continue collecting stamps.

If you leave this field empty, the reward becomes available after the customer collects the last stamp. For example, if the card requires 10 stamps, the reward appears after the 10th stamp.

Tip: If you want to offer multiple rewards and visually display them in the card design, see How to set up a stamp card with multiple rewards for additional configuration steps.

Note: The reward is not issued automatically — the customer earns it and can redeem it according to the program rules.

Select Yes if you want earned rewards to be redeemed at the moment the stamp is issued. This assumes the customer did not decline the reward during their visit.

Tip: We recommend setting this to No and redeeming rewards manually using the scanner app. This gives you more control over when and how rewards are applied.

Activate or deactivate the referral program using the Active and Inactive radio buttons.

Tip: We recommend activating the referral program with every promotion card you create. It's a cost-effective way to grow your customer base without additional advertising spend.

Choose when the referral bonus is issued:

Configure the following:

Add links displayed on the back of the card. You can add up to 10 active links.

Customers can tap links on the back of the card to visit your website, call your business, or send an email directly from their phone.

Click the remove button to delete a link, or click Add Link to add another.

Add links for customer reviews. Customers see these links after receiving a stamp and rating their visit. If a customer provides a positive rating (4 or 5 stars), they are prompted to leave an additional review on the linked platform. The link appears on the back of the card.

Supported platforms include Google Maps, Yelp, Foursquare, and Facebook.

Tip: Linking to your Google Maps listing helps boost your search ranking and local SEO.

Enable the toggle to include terms of use on the card. Enter your terms in the text field and provide a link to your full terms and conditions. Customers see this link on the registration form and the back of the card.

Enter your company name, email, and contact number. These details appear on the back of the card for customers who need support.

Once all details are filled in, click Finish.

Tip: You can install an inactive card to test it. Activate the card once you're confident in the settings. While the card is inactive, only 10 people can install it — this is enough for testing.

After clicking Finish, the Preview popup appears.

Important: Before activating, you can issue up to 10 test cards to your own devices, friends, or teammates. Once you activate the card, you cannot change the card type, loyalty program terms, card expiration dates, stamp expiration dates, or card issuing form fields.

After activation, you can download promotional materials in PDF format (A5 or A4) for printing. Use these as table tents near your cashier zone or at your point of sale.

This happens when a customer installed the card before you changed the total number of stamps required.

For example, if the card was originally configured with 10 stamps and a customer installed it at that point, their wallet saved the old configuration. If you later update the card to 8 stamps, customers who installed before the change still see the old value because Apple/Google Wallet does not automatically update the card's original template.

Important: The number of stamps should not be changed after the card is published and installed by customers, even if the customer has not activated it yet.

To synchronize the card with the new template:

After reinstalling, the stamp requirement and remaining stamps will display correctly.

Once you activate the card, you cannot change the card type, loyalty program terms, card expiration dates, stamp expiration dates, or card issuing form fields. Make sure to test the card thoroughly before activating.
