Designing your cards.

Customize the look and feel with logos, backgrounds, and icons

Jul 21, 2026

Visual design makes your stamp cards memorable and engaging. Upload custom images, choose recognizable icons, and create a branded experience that customers love.

Visual elements

Your stamp card includes several customizable visual elements:

  • Logo: Your business or program logo
  • Background: A full-card background image, or a background colour
  • Text colour: The colour of the text on the card
  • Stamp icon: The symbol shown on each stamp

The stamps themselves are frosted glass: they render as a soft, translucent overlay that sits on any background (light or dark, photo or solid colour) and stay consistent from the card face to the progress view. There is nothing to choose: you no longer set stamp colours by hand, so your stamps always look right.

Google Wallet: If you enable Google Wallet on this stamp card, the wallet pass uses your logo and background color. Stamp card passes do not use the background image (Google's Generic pass type does not support hero images). Upload a logo to avoid a generic icon. See Google Wallet Pass Design for details.

All of these live on the Design tab of the stamp card form.

The Design tab with color pickers, the stamp icon picker, and the live preview of the finished card.

Background and text colors

Background color

Field: Background color Default: #047857

The card's base color, chosen with a color picker. Without a background image it fills the card; with one, it lies over the image as a tinted overlay (see opacity below).

Text color

Field: Text color Default: #FFFFFF

The color of the title, description, and progress text on the card face. Keep strong contrast with your background color and image.

Choosing stamp icons

Icon picker

Stamp cards use emoji as stamp icons, so you can choose from a large set of recognized symbols.

To select an icon:

  1. Open the Stamp icon picker on the Design tab
  2. Browse the categories Popular, Food, Retail, Services, Rewards, and Emojis, or search
  3. Click your preferred icon
  4. See the live preview on the stamp card

The default icon is ⭐.

Stamp count options

Choose from six curated stamp counts, each designed for the best visual display:

Stamps Grid Layout Best For
5 5×1 (single row) Quick rewards, simple programs
6 3×2 grid Balanced, compact design
8 4×2 grid Popular choice, symmetrical
9 3×3 grid Perfect square, premium feel
10 5×2 grid Traditional loyalty programs
12 4×3 grid Extended programs, higher value rewards

The six counts are curated so your stamp cards always display balanced, pixel-perfect grids that look professional on all devices.

Icon best practices

Choose recognizable symbols: Customers should recognize what your business offers.

Ensure cross-platform compatibility: Test that your icon displays on iOS, Android, and web browsers.

Consider light and dark mode: Some emojis look different in dark mode. Preview both.

Match your brand: The icon should align with your business identity and the reward offered.

Keep it simple: Avoid complex icons that don't hold up at small sizes.

Uploading logo images

Logo specifications

Format: JPEG, PNG, JPG, or GIF Size limit: 1 MB Dimensions: 20×20 minimum, 800×800 maximum Aspect ratio: 1:1 (square) works best

Logo design tips

Use the full allowed size: Upload close to 800×800px for crisp display on all devices.

Square format works best: Circular or square logos fit best. Horizontal logos may be cropped.

Transparent backgrounds: PNG with transparency looks professional and adapts to any background.

Ensure readability: Logo should be clear at small sizes.

Brand consistency: Use your official logo for recognition and trust.

Uploading process

  1. Go to the Design tab in your stamp card form
  2. Click Choose File under Logo
  3. Select your image file
  4. Preview appears
  5. Adjust if needed or confirm

To replace:

  1. Click Remove on current logo
  2. Upload new image

Adding background images

Background specifications

Format: JPEG, PNG, JPG, or GIF Size limit: 2 MB Dimensions: 320×240 minimum, 1920×1440 maximum Aspect ratio: Horizontal images work best

Background design tips

Choose relevant imagery:

  • Coffee beans for coffee shops
  • Food photography for restaurants
  • Product shots for retail
  • Lifestyle images for services

Ensure good contrast: Background should not make text unreadable. Use the opacity slider to adjust.

Avoid busy patterns: Simple, clean backgrounds work better than complex patterns.

Test on mobile: Backgrounds look different on small screens. Preview on various devices.

Brand alignment: Use images that reflect your brand aesthetic and values.

Background color opacity

Field: Background color opacity Range: 0-100% Default: 75%

Controls how much your background color tints the card. With a background image, the color sits over the image as an overlay: the higher the value, the more the color covers the photo and the easier the text reads.

Lower values (30-50%):

  • The photo shows through
  • The color adds a light wash
  • Text needs a high-contrast image to stay readable

Medium values (50-75%):

  • Balanced: the image adds atmosphere, the color keeps text clear
  • A safe zone for most photos

Higher values (75-100%):

  • The color dominates and the image becomes a texture
  • Maximum text readability

Recommendation: Start at the default 75% and lower it until the image shows through as much as you want, checking the text stays readable.

Uploading process

  1. Open the Design tab
  2. Click Choose File under Background
  3. Select your image
  4. The preview appears with the current color overlay
  5. Adjust the opacity slider
  6. The preview updates as you go
  7. Save when satisfied

Responsive design considerations

Your stamp card displays on various screen sizes:

Mobile (most common):

  • Logo: 80-100px
  • Background: Scales to fit
  • Icon: 40-50px per stamp

Tablet:

  • Logo: 100-120px
  • Background: Wider display
  • Icon: 50-60px per stamp

Desktop:

  • Logo: 120-150px
  • Background: Full width
  • Icon: 60-80px per stamp

Design for mobile first: Ensure your logo and background look great on small screens, and they'll scale to larger displays.

Accessibility considerations

Color contrast

Ensure sufficient contrast between:

  • Text and background
  • Logo and background
  • Icons and background

Test with:

  • Light mode
  • Dark mode
  • Various screen brightness levels

Visual clarity

Avoid:

  • Light text on light backgrounds
  • Dark text on dark backgrounds
  • Low-contrast color combinations

Prefer:

  • High contrast
  • Clear, legible fonts
  • Simple, recognizable icons

Updating design elements

Editing existing stamp cards

To update visual elements on an active stamp card:

  1. Go to the Stamp cards list
  2. Click Edit on the program
  3. Go to the Design tab
  4. Upload new images or change colors and opacity
  5. Click Save

Changes take effect at once:

  • Customers see updated design
  • Existing enrollments retain progress
  • No impact on stamp counts or rewards

A/B testing designs

Test different visual approaches:

Create variations:

  1. Create a second stamp card with the same rules and rewards
  2. Change only the visual elements
  3. Run both programs at the same time
  4. Compare enrollment and completion rates

Analyze results:

  • Which design attracts more enrollments?
  • Which has higher completion rates?
  • Which generates more customer feedback?

Implement winners:

  • Keep the best-performing design
  • Deactivate underperforming variations
  • Apply learnings to future programs

Image optimization

File size

Keep images under recommended limits:

  • Logos: 500KB or less
  • Backgrounds: 2MB or less

Benefits:

  • Faster page loading
  • Better mobile experience
  • Reduced bandwidth usage

Tools for compression:

  • TinyPNG (online)
  • ImageOptim (Mac)
  • Squoosh (web-based)

Format selection

PNG:

  • Best for logos with transparency
  • Supports alpha channel
  • Larger file sizes

JPG:

  • Best for photographic backgrounds
  • Smaller file sizes
  • No transparency support

GIF:

  • Accepted, but not often the right choice
  • Limited colors and larger files than JPG for photos

Recommendation: PNG for logos, JPG for photos. The stamp card uploads accept JPEG, PNG, JPG, and GIF; they do not accept WebP.

Troubleshooting design issues

"Image file too large"

Cause: File exceeds size limit Solution: Compress image before uploading

"Image appears stretched"

Cause: Wrong aspect ratio Solution: Use recommended dimensions (square for logo, 2:1 for background)

"Text is unreadable"

Cause: The photo shows through too much Solution: Raise the background color opacity toward 75-90% so the color overlay carries the text, or pick a text color with more contrast

"Logo looks blurry"

Cause: Low resolution image Solution: Upload higher resolution (minimum 500x500px)

"Background doesn't display"

Cause: File format not supported or upload failed Solution: Use JPEG, PNG, JPG, or GIF and try uploading again
