Google Wallet and Apple Wallet
This is the feature that separates a forgotten program from a used one. A card tucked into the phone wallet is found in two seconds, unlike a piece of cardboard at the bottom of a bag.

The card joins their tickets and passes
From the card open in their browser, your customer taps the add to wallet button. The card installs itself next to their boarding passes and event tickets.
It carries your business name, your logo if you added one, and the exact state of their counter.
Updates happen on their own
This is the point merchants grasp last, and yet it is the most useful one to explain at the counter.
You scan
The stamp is added in Aster. Nothing else to do, and your customer does not need to open anything.
Their card changes
Aster notifies the customer's wallet, which fetches the new version. The counter goes from six to seven, with no intervention.
They see it later
When they reopen their wallet, the card is up to date. That small moment is what keeps the habit of coming back alive.
Your promotions appear on it
When you launch a promotion, its message appears directly on the card, in every customer's wallet, for the whole period you set. It disappears automatically on the end date.
Customers who ticked the box to receive your offers also get a notification on their phone. The others see the message on their card but are not disturbed.

Android and iPhone, no distinction
Your merchant app only exists on iPhone, but your customers can have any phone.
Google Wallet, on Android
The card is added in one tap and updates automatically. Promotion messages appear on it and vanish by themselves on their end date.
Apple Wallet, on iPhone
Same behaviour. The card updates itself after each scan, and the customer can reach it from their lock screen.
What can go wrong
The update is sent immediately after the scan, but how quickly it shows depends on the customer's phone and connection. It usually arrives within seconds. If in doubt, their card in the browser always shows the exact state, and that is the one that counts.
The customer most likely did not tick the optional box when signing up. The message is on their card, but no notification is sent to them. That is anti-spam law, not a forgotten setting.
Their stamps are not lost. They rescan your code, enter the same number, get their card back and can add it to the wallet again.
