What Is a Wallet Pass? Apple and Google Wallet Explained
A wallet pass is a digital card that lives in Apple Wallet or Google Wallet on a smartphone: a boarding pass, concert ticket, loyalty card, or stamp card. It's not an app—it's a card inside an app that's already on the phone. That's exactly what makes it interesting for shops: your customers get your card without downloading anything, and it updates itself. This article explains what a wallet pass is, how it works, and what it can do for your business.
Wallet Pass: The Simple Definition
Think of the wallet on your phone like a physical wallet. Inside are cards. Each of these cards is a wallet pass. Apple calls them "cards" or "passes" in Apple Wallet; Google uses the same terms in Google Wallet. It's the same thing: a small digital document with a front and back, a barcode or QR code, and a few fields that can change.
The key difference from an app: a wallet pass has no separate code to install. It's pure content that the wallet displays. That means no App Store, no updates to download, and no storage space it takes up.
Types of Wallet Passes
You encounter wallet passes more often than you think. The typical kinds:
| Type | Example | What Changes |
|---|---|---|
| Boarding pass | Flight, train | Gate, seat, delay |
| Ticket | Concert, cinema, museum | Entry status |
| Coupon | Retailer discount code | Validity, remaining value |
| Loyalty card | Chain store card | Points balance |
| Stamp card | Your shop's loyalty card | Number of stamps, reward |
| Membership card | Gym, club | Status, expiration |
For you as a shop owner, the stamp card is the relevant type. It works technically the same as a large chain's loyalty card, except you get it without needing a developer. How it works in practice is described in Digital Stamp Card: How It Works.
How a Wallet Pass Gets on Your Phone
The process is similar for all types and takes seconds:
- A link or QR code. The airline sends a link by email; your shop displays a QR code on a sign.
- A quick preview. Your phone shows what the card looks like.
- One tap. "Add to Apple Wallet" or "Add to Google Wallet". Done.
On iPhone, Apple Wallet comes preinstalled. On Android, Google Wallet is on most devices; if not, it's free from the Play Store. So your customer usually doesn't need to install anything. Details for both systems are in Stamp Card in Apple Wallet and Stamp Card in Google Wallet.
How a Wallet Pass Updates
This is the feature that sets a wallet pass apart from a photo or PDF. A pass is connected to the provider who issued it. When something changes, the card in the wallet updates:
- The airline changes the gate; the boarding pass shows the new gate.
- Your team scans the stamp card; the card shows one more stamp.
- You change your card's design; all existing cards show the new design.
The customer doesn't have to do anything. They open their wallet, and the card is current. That's why a digital stamp card always shows the right status, while a paper card waits for the stamp in a drawer.
What a Wallet Pass Can Do Extra
Beyond display, wallet passes have two capabilities that make them so valuable for customer loyalty.
Notifications. A pass can send a message to the lock screen. For a boarding pass, it's a gate change; for your stamp card, it could be an action like "Today only: buy one get one free" or a reminder that stamps are running low. The message appears as a wallet notification without the customer granting app permission. Marketing messages should still only go to customers who've opted in; with stampa, that's a separate checkbox, off by default.
Location-based. A pass can have a location attached. When the user is nearby, the wallet can suggest the card on the lock screen. For a boarding pass, that's the airport; for your stamp card, it's your shop. With stampa, this is called geofencing and is included from the Growth plan onward.
What Your Shop Needs
Here's where the real hurdle lies, and it's not on the customer's side. To issue wallet passes, a provider needs an Apple developer account with certificates and a Google issuer registration, plus a server that creates cards, updates them, and sends notifications. For a single shop, that's neither practical nor cost-effective.
That's why services like stampa exist—they handle all of that. For you, it comes down to:
- Sign up, free up to 100 active customers, no credit card needed.
- Your logo and colors are pulled in automatically from your website.
- Set the number of stamps and the reward.
- Print the ready-to-print sign with QR code.
- Scan with your team's smartphone.
Everything technical behind the scenes—from issuing the card to updating it to sending notifications—runs in the background.
Example: A Wallet Pass from the Customer's Perspective
A customer walks into a bakery, sees the sign, and scans the QR code. She taps "Add to Apple Wallet". Now the bakery's card sits next to her train ticket in her wallet.
On her next visit, she shows the card; the cashier scans it with a smartphone, and the card shows one of eight stamps. Two weeks later, a message appears on her lock screen: "Breakfast special today—free croissant with coffee." At the eighth stamp, the card shows the reward is ready, and the bakery redeems it with one tap in the dashboard.
The customer never opened an app, never entered a password, and never searched for a paper card. That's a wallet pass.
Conclusion
A wallet pass is a digital card in Apple Wallet or Google Wallet that arrives without an app, updates itself, and can send messages to the lock screen. For shops, it's the easiest way to stay on your customers' phones long-term. The provider handles the technical side; you just design the card. If you want to see your own wallet pass, you can get started with stampa for free—up to 100 active customers, no credit card required.
