Stampioo vs PassKit (2026): a finished loyalty card or a pass platform for developers?

PassKit and Stampioo rarely compete for the same buyer, but they turn up in the same searches because both issue loyalty cards to Apple Wallet and Google Wallet. PassKit is the pass platform behind Loopy Loyalty, sold directly to developers and larger teams, billed by team size and pass volume. Stampioo is a loyalty card, which is what most people mean by a digital stamp card, built for a single shop or a handful of locations and sold at one price. This page is for anyone who has landed on both and wants to know which door to walk through.

A word on bias: Stampioo publishes this page, and PassKit is the parent of a direct competitor of ours. We have kept to what each pricing page says on 3 November 2026, linked the pages, shown our arithmetic for the per-pass example, and written the “choose PassKit if” list to be as useful as the other one. Where PassKit’s pricing page does not state something, we say so instead of guessing.

The two tools in one table

What PassKit is

PassKit sells the plumbing: a pass designer, an API and the operational tooling to create, update and manage passes in Apple Wallet and Google Wallet, for loyalty, membership, coupons and events. On 3 November 2026 its pricing page explains that the monthly platform fee depends on how many team members need access, from $39.50 for one member to $249.50 for unlimited members, and that usage is billed on the multi-use pass records you keep and the single-use passes you issue each month. The first 250 of each are included. After that, the rate card charges $0.045 per multi-use pass per month for passes 251 to 2,500, $0.034 for 2,501 to 5,000, $0.023 for 5,001 to 10,000 and lower rates at higher volumes; single-use passes cost $0.0945 each in the first paid tier. Invoices are issued after each billing period, the trial is 45 days, and the page does not say whether a card is needed to start. Stamp cards as a ready-made template are not mentioned on the pricing page: that is what PassKit’s separate product Loopy Loyalty is for.

A worked example, by our reading of the rate card as tiered: a café with 1,000 customers holding a Wallet card would pay the $39.50 platform fee plus 750 passes at $0.045, about $73 a month. With 3,000 cards it would be $39.50 plus 2,250 at $0.045 plus 500 at $0.034, about $158 a month. The per-pass rate drops as you grow, but the bill grows with your customer list, which is the opposite of a flat price.

What Stampioo is

Stampioo is the finished product that a platform like PassKit could be used to build. The customer scans a QR code, fills in a short form and saves the loyalty card to Apple Wallet or Google Wallet. Staff stamp with the phone camera in the browser, the card updates on the lock screen, the reward appears when the card is full, and you can reach customers with targeted push campaigns and nearby reminders. Starter costs €29 a month excluding VAT, or €23 billed yearly, for one programme and one location with three team members; Pro costs €49 for five programmes, five locations, ten team members, advanced analytics and ten campaigns a month. Cards, customers and scans are unlimited on every plan, so a programme that takes off costs the same as one that does not. The 30-day trial needs no card details, and the full plan list is on the pricing page.

Where Stampioo loses to PassKit: there is no API and no POS integration, so you cannot connect it to your own software; there is only one pass type, a stamp-based loyalty card, with no coupons, membership or event passes; there is no white-label option for building your own product; the trial is 30 days to PassKit’s 45; and there is no volume pricing for a developer serving hundreds of businesses. There is also no free plan, few public reviews, and prices in euros and kronor only. Stampioo is run by Allvia AB in Sweden and is your GDPR data processor, but the service runs on Netlify, which may process data in the United States under the EU–US Data Privacy Framework and standard contractual clauses, as our privacy policy says.

Choose PassKit if

• You have a developer and want to design your own passes, integrate them with your systems through the API, or build a loyalty product for other businesses.
• You need pass types beyond a stamp card: memberships, coupons, event tickets, single-use offers.
• Your volumes are large enough that the falling per-pass rate beats a flat subscription, or you want to pay only for the passes you actually keep.
• You want the longest trial of any tool in this category: 45 days.

Choose Stampioo if

• You run a café, salon, restaurant or shop and want a loyalty card at the till this week with nobody writing code.
• You want a predictable bill: €29 a month for one location, €49 for five, whatever the number of cards.
• Your customers or staff speak a language other than English: Stampioo comes in 29.
• You want the sign-up form, the scanner, the segments for push campaigns and the nearby reminders included rather than built.
• You would rather have one simple product than a platform with a rate card.

What the sources get wrong

Comparison pages often put PassKit in the same row as Loopy Loyalty, Stamp Me and Stampioo and quote a “from $39.50” price as if it were a subscription for a shop. It is a platform fee that excludes the per-pass charges above 250 passes, and it buys tools, not a finished card. The reverse mistake is to treat Stampioo as a platform: it is not, and a developer who needs an API should not start a trial expecting one.
