Loyalty, explained plainly.

What we learned building Kanz, and what can be explained without jargon: the card, the stamps, the returns, the messages.

    What data a loyalty card should collect

    A phone number. The rest is optional, and the year of birth is never asked for and never stored. What Kanz collects, what it refuses, and what a customer undoes in one move.

    A verified return, and why open rates lie

    An opened email is not a visit. At Kanz a verified return is a scan at your counter, and the function that records that proof refuses to run without the visit ID.

    Loyalty that asks for no app at all

    A wallet pass asks for no installation at all, and it can request neither location, nor contacts, nor photos: it has no code to run, so it has nothing to ask for.

    What time to send a message to your customers

    Ten, by default. But the right number is a calculation: the one that drops the cost of your reward below what an extra visit brings in. Here is the sum, and the 40% rule.

    Why an Apple Wallet card updates later

    On Android the counter changes at once; on iPhone it changes when the customer opens their wallet. It is not a bug, it is a protocol Kanz cannot speak from where it runs.

    What a digital loyalty card costs

    A monthly subscription, and a credit spent only when a message really goes out. The real prices of the three plans, what a credit buys, and the sum that says how many you need a month.

    How the Kanz loyalty card works in the Wallet

    The Kanz card is a loyalty card your customer adds to Apple Wallet or Google Wallet, with no app to install. Here is what happens at sign-up, at the counter, and between visits.

    Messaging customers on WhatsApp without losing your number

    WhatsApp does not ban commercial messages, it bans accounts that behave like software. What Kanz refuses to do, the guardrails you set yourself, and why the card stays the safest channel.

Comparing us with something else?

We put Kanz next to five other loyalty tools, with a link to the vendor's page and the check date on every line.

Your regulars have already been in. Bring them back.

Kanz is in closed beta: we open in small groups so we can follow each shop closely. Once your place opens you get 10 free returns and a 30-day trial, no card.

Your address is enough. We'll tell you the moment a place opens.
