Plastic card vs. wallet card: costs, effort, impact
Plastic loyalty card or wallet card—that's the question many shop owners face when the old paper card has had its day and something more premium is needed. The short answer: plastic wins on feel and works with chain POS systems, but the wallet card wins on cost, setup time, reach, and everything that happens after. This comparison walks through both options for a small shop, line by line.

Costs: What plastic really adds up to
With plastic printing, you're not just paying for the card. Here's what adds up:
- Printing. Per-unit cost drops with volume. For small quantities at a single shop, it's highest. Personalization with barcodes or numbers adds more.
- Setup and shipping. Layout fees, print approval, delivery. Every change starts from scratch.
- Card reader or POS system. A plastic card with function needs something to read it. Either a scanner at checkout or a POS system with a customer module.
- Waste. Some cards are lost, never handed out, or sit in a box after the next redesign.
Example: 500 cards with barcode, plus layout and shipping, plus a basic card reader. Depending on the vendor, that's easily several hundred euros before the first customer holds a card. And if you change the reward, you print again.
The wallet card has no per-unit costs and needs no hardware. Stamping happens via scan with your team's smartphone. With stampa, you start free up to 100 active customers; after that, plans start at €29/month, cancel anytime. See all pricing at What does a digital stamp card cost.
Effort: weeks vs. minutes
The plastic card needs lead time: create layout, get quotes, approve print, wait for delivery, set up card reader, train team. Realistically, two to four weeks pass before the program runs.
The wallet card you set up in a browser. During onboarding, stampa automatically pulls your logo and colors from your website, you choose stamp count and reward, and AI creates a print-ready poster with QR code. The poster is the only thing you print. You train your team in under 15 minutes. Digital loyalty card: what it can do and how to launch it covers this in detail.
Impact: What the card does after you hand it out
This is where the real difference lies. A plastic card is a passive object after it's handed out. It sits in a wallet, sometimes at home, and never reaches out. If a customer doesn't come for three weeks, you don't know, and neither do they.
The wallet card is a channel:
- Push notifications appear as wallet alerts on the lock screen. An action, a reminder about the last missing stamp, an offer for today only.
- Automations bring back inactive customers, celebrate birthdays, and boost slow days without you lifting a finger.
- Geofencing reminds customers when they're near your shop.
- The dashboard shows live how many customers are active, how many stamps given, how many rewards redeemed.
Real-world example: Tuesday afternoon is slow. With the wallet card, you send a message at 2 p.m. to all opted-in customers: double stamps on everything until 5 p.m. With a plastic card, you can only hope someone walks by.
A plastic card can do all this only if you connect it to a POS system with a customer database and email marketing. That's the overhead of a chain, not a single shop.
Loss, forgetting, and changes
Three everyday problems that come up regularly with plastic:
- Card forgotten. Customer is here, card isn't. No stamp, no points, some frustration. With wallet, the card is on the phone the customer has anyway.
- Card lost. With plastic and no central database, the balance is gone. With wallet, the customer rescans, and depending on the provider, the balance stays.
- Reward changes. With plastic, that means a reprint or a sticker. With wallet, you change the card once, and all customers see it instantly.
Data protection
Both options process customer data. With plastic and POS, you write your own data protection policy for the loyalty program and collect marketing consent if you want to email customers. With stampa, an editable data protection policy is auto-generated and hosted for your shop, and marketing consent is a separate checkbox that defaults to off. You don't need your own website. Details at GDPR and loyalty programs.
When plastic is still the right choice
There are cases where the plastic card fits: if you already have a POS system with a customer module and the card is just for ID. If your customers mostly don't use smartphones. Or if the card is part of a paid membership and the feel is part of the concept. For most small shops, none of that applies. And even then, you can combine both: the plastic card stays for customers who want it, and everyone else gets the wallet card from the same poster.
Bottom line
The plastic loyalty card is premium but expensive to launch, passive in daily use, and cumbersome to change. The wallet card has no per-unit costs, needs no hardware, is set up in minutes, and can reach, remind, and measure customers. For a single shop, it wins on almost every line. With stampa, you set it up in minutes, free up to 100 active customers, no credit card needed. Start free now.
