Wallet Card vs. SMS: Which Channel Fits Your Shop?

The figures and scenarios in this article are illustrative: adapt them to your margins and your own data. They are not EasyFid customer results. See how to measure your results.

A customer hasn't been back in three weeks. You'd like to reach out, but the first question that comes up is almost always the same: how much will it cost, and how? Many shop owners default to SMS, and then hesitate in front of the bill that climbs with every recipient — or simply give up on staying in touch at all for lack of a marketing budget.

There is, however, a tool most small shops already have without thinking of it that way: the digital loyalty card sitting in Apple Wallet or Google Wallet, whose balance stays automatically up to date at no cost per customer. It isn't a messaging channel — it doesn't send anything — but it means the customer never has to wonder where they stand. In this article, we compare this always-current Wallet card with SMS marketing: real cost, reach, legal constraints, and when each one actually makes sense.

The Wallet card: an always-current balance, not a messaging channel

When a customer adds your loyalty card to Apple Wallet or Google Wallet, they're carrying a small, always-accurate summary of their relationship with your shop: their points or visits, one tap away from their home screen. Every time you scan their card to credit a visit or points, the card updates instantly — but nothing is pushed to the customer and nothing is sent to them. They simply find the right number the next time they open their Wallet, whether that's five minutes later or three weeks later.

The key difference with SMS: there is no cost per customer and no message to write. Whether you scan 50 or 1,500 customers a month, the price doesn't change — it's a feature included in the subscription, not billed per send, because there's nothing being sent. With EasyFid, the balance updates live in the Wallet at every checkout, which reinforces the customer's habit of checking their card before they even think about calling ahead or texting to ask about their rewards.

• Free and unlimited: no variable cost, no matter how many customers you scan.
• Zero friction: the customer already has the card on their phone; there's nothing extra for them to do to see the current balance.
• Not a push channel: the card doesn't reach out to the customer — it's simply accurate the moment they choose to open their Wallet and look at it.
• Tied to a real visit: the balance only changes when you've just credited an actual purchase, so it always reflects something real.

SMS marketing: a real messaging channel, but a paid one

SMS remains a remarkably effective channel for actively reaching a customer: it needs neither a recent smartphone nor an app, and nearly every message gets read. Unlike the Wallet card, it goes out and finds the customer wherever they are — that's a strong case for a one-off campaign that needs to reach as many people as possible, including those who don't have a digital loyalty card yet.

But that reach comes at a direct cost: professional sending platforms typically charge between €0.05 and €0.08 per marketing text. On a base of 800 customers, a single campaign can cost between €40 and €65 — multiplied by however many times you send one over the year. SMS marketing also comes with an unavoidable legal requirement: explicit consent (GDPR opt-in) must be collected before any commercial message, with a clear way to opt out on every message. In practice, this means running it through a dedicated sending tool, separate from EasyFid.

• Variable cost: billed per message, so the budget grows mechanically with your customer count.
• Consent required: collecting and keeping proof of opt-in is required under GDPR.
• 160 characters: a short format that limits how personal the message can be.
• Actively delivered: reaches customers without prompting from them, including those without a Wallet card set up.

Wallet card vs. SMS: the numbers side by side

SMS wins on one thing the Wallet card was never built to do: actively landing in front of the customer at a moment of your choosing. On everything else, the comparison favors the Wallet card:

• Cost: free and unlimited for the Wallet card, billed per message for SMS.
• Consent: already implied when the customer added the card, for the Wallet; a separate, documented GDPR opt-in for SMS.
• Persistence: the balance stays accurate on the card as long as it's active in the Wallet, while a text quickly disappears into the message thread.
• Brand image: the Wallet card carries your name and colors every time it's opened; a text comes from a number that's often generic.

Which one to use depending on your situation

For a local shop starting out with digital loyalty, the Wallet card should be the default: it costs nothing to keep current and reaches a base of customers who are already engaged — the ones who took the time to add the card. Its balance updates automatically every time you record a visit, with no campaign to plan and no message to write.

SMS keeps its place in specific cases: a one-off campaign with high visibility, an event where you also want to reach customers who don't have a loyalty card yet, or an urgent message (an exceptional closure, a product recall). Sent through your own tool and with proper consent, SMS complements the Wallet card rather than replacing it. To build a coherent outreach strategy over time, our guide to setting up a merchant loyalty program details how to combine these levers with your points scale.

On the budget side, it's also worth comparing the whole picture: a digital loyalty subscription with the Wallet card included costs a fixed, predictable amount every month, regardless of how many customers you scan — unlike SMS, where every campaign adds a line to the bill.

Good practices so customers don't tune you out

The Wallet card only changes when you credit a real visit, so there's no way to overuse it — it isn't a broadcast tool and never will be. Where the real risk lies is entirely on the SMS side, which you fully control and can send as often as you like: send it too often and it starts to feel like spam, and a customer can remove your loyalty card from their Wallet just as easily as they added it if they feel pestered.

• Only scan for real transactions: crediting points just to force a balance change turns a trustworthy card into noise.
• Say it out loud when it matters: if a customer is one visit away from their reward, mention it at checkout right as you scan their card — the accurate balance they see when they next open their Wallet reinforces what you just told them.
• Keep SMS rare: one or two messages a month is usually enough to stay effective without wearing customers down.
• Simple segmentation for SMS: reserve certain messages for inactive customers rather than texting your entire list every time.
