How to get customers to join your loyalty programme

The point-of-sale ask: your most powerful tool

Nothing drives loyalty sign-ups more effectively than a verbal offer from a real person at the moment of purchase. This is not a guess. Every piece of data on loyalty programme adoption points to the same conclusion: staff asking customers directly accounts for 60 to 70 percent of all sign-ups. Everything else, social media, signage, email, QR codes on receipts, is supplementary.

The reason is simple psychology. A customer who has just bought something is in a positive, engaged state. They have chosen to spend money at your business, which means they already value what you offer. A staff member who says "would you like to start earning a free coffee?" at that exact moment is making an offer to someone who is primed to say yes.

The phrasing matters enormously. "Would you like to join our loyalty programme?" sounds like bureaucracy. "Would you like to start earning a free [reward]?" sounds like a gift. Lead with the benefit, not the mechanism. Customers do not care about your programme. They care about free things, special treatment, and feeling valued.

Make it a standard part of every transaction. Not optional, not "when you remember," not "if the customer looks interested." Every customer, every time. Staff who ask consistently see sign-up rates of 30 to 50 percent. Staff who ask occasionally see rates below 10 percent. The difference is not talent or charisma. It is consistency.

Counter displays and self-join QR codes

Not every customer will be offered the programme verbally. Some visit during a rush when staff are too busy for the conversation. Others are regulars who were asked before and said "maybe later." Counter displays with self-join QR codes capture these customers without requiring any staff effort.

A self-join QR code is a link to your programme's sign-up page, presented as a scannable code. Place it on a small card or table tent near the till, at tables if you have seating, and at the entrance or exit. When a customer scans the code with their phone camera, they are taken directly to a page where they can join the programme and download the Stampet app.

The display should be visually clear and communicate the value proposition in under three seconds. "Earn a free coffee. Scan to join." is more effective than a paragraph explaining how the programme works. Customers will either scan it immediately or not at all. You have one glance to convince them it is worth the five seconds of effort.

Self-join codes are also ideal for businesses where the staff interaction happens away from the payment counter, such as restaurants where food is ordered at the table but paid at the till. A table tent lets customers join while they are waiting, which is a moment of low friction and high attention.

Social media and online channels

Social media works best for announcing your programme and keeping it visible, rather than as a primary sign-up channel. Post about your loyalty programme when you launch it, and then mention it regularly as part of your ongoing content. "Did you know you can earn a free haircut just by visiting us?" as an occasional post keeps the programme in your audience's awareness.

Include a direct link to your programme's join page in your Instagram bio, your Facebook page, and any other profiles where customers might find you. This turns casual browsers into programme members without requiring them to visit your physical location first. It is particularly valuable for attracting customers who follow you online but have not yet visited, or who visited once and need a reason to return.

If you run a website or have a Google Business Profile, add your loyalty programme there too. A customer who searches for your business and sees "loyalty programme: earn a free [reward]" on your profile has one more reason to choose you over the competitor next door. These are small touches, but they compound over time.

Do not over-invest in social media promotion at the expense of the point-of-sale ask. Social media might drive 5 to 15 percent of your sign-ups. The staff ask drives 60 to 70 percent. Get the in-store experience right first, then use online channels to extend your reach.

Receipt messaging and physical touchpoints

If your till system supports custom receipt messages, add a line about your loyalty programme to every receipt. "Earning stamps? Ask about our loyalty programme!" or "Download Stampet to earn free [reward]" costs nothing to implement and reaches every single customer who receives a receipt.

Receipts are surprisingly effective because they are read at a moment of reflection. The customer has just paid and is processing the transaction. A short loyalty message at that moment plants a seed that may not result in an immediate sign-up but makes the customer more receptive next time a staff member offers the programme.

Other physical touchpoints to consider include packaging (stickers or printed messages on takeaway bags or boxes), menu inserts, and business cards left at the counter. Each of these is a low-cost opportunity to remind customers that the programme exists. None will drive large numbers of sign-ups on their own, but together they create an environment where the loyalty programme feels like a natural part of doing business with you.

Welcome stamps and the psychology of getting started

One of the most effective tactics for converting a "maybe" into a "yes" is offering a welcome bonus. When a customer joins, give them their first stamp immediately. This is not just generosity. It is a deliberate application of the endowed progress effect, a psychological principle that shows people are significantly more likely to complete a goal when they feel they have already made progress towards it.

A customer who joins a 10-stamp programme and already has 1 stamp is psychologically in a very different position from a customer staring at an empty card. The first customer has started. They have momentum. Abandoning the card feels like losing something they already have. The second customer has not yet committed, and walking away costs them nothing.

Research on this effect shows completion rate improvements of over 80 percent when customers start with partial progress. For the cost of a single stamp, which has no direct monetary value, you dramatically increase the likelihood that the customer will complete the entire card and earn a reward. This is one of the highest return-on-investment tactics available in loyalty programme design.

You can also use the welcome bonus as part of your staff script: "If you join today, you will get your first stamp free, so you are already on your way to a free [reward]." This reframes the offer from "sign up for a programme" to "start earning something right now," which is a much more compelling proposition.

Wallet passes: reducing the friction to zero

Some customers will happily download the Stampet app and use it at every visit. Others will hesitate because they do not want another app on their phone. Wallet passes solve this by letting customers save their loyalty card directly to Apple Wallet or Google Wallet, the same place they keep payment cards and boarding passes.

A wallet pass means the customer's QR code is always accessible with a double-click of the side button or a swipe from the lock screen. No app to open, no login to remember, no storage space consumed. For customers who are resistant to downloading apps, this can be the difference between joining and walking away.

When staff offer the programme, mentioning the wallet pass option can overcome the most common objection: "I do not want to download another app." A response like "You do not have to. You can save it straight to your Apple Wallet and it is always there" addresses the concern directly and keeps the conversation moving towards a yes.

Tracking your sign-up rate

You cannot improve what you do not measure. Track your sign-up rate weekly: how many new members joined compared to how many customers you served. In the first week, aim for 15 to 25 percent. By the end of the first month, you should be approaching 30 to 40 percent. By month three, a well-run programme should have 40 to 60 percent of regular customers enrolled.

If your sign-up rate is below 10 percent after the first week, the problem is almost certainly that staff are not asking consistently. If it is between 10 and 20 percent, staff are asking but the offer or the join process has friction that needs smoothing. If it is above 30 percent, your acquisition engine is working and you can focus on retention and engagement.

Break the numbers down by shift and by staff member if your platform supports it. This is not about creating a league table or pressuring individuals. It is about identifying where the gaps are so you can provide targeted support. A staff member with a 5 percent sign-up rate may simply need a better script or more confidence, not a reprimand.

Beyond the first hundred

The first 100 members are the hardest because you are building a new system and new habits simultaneously. Once you pass that milestone, growth becomes self-reinforcing. Existing members tell friends. Customers see others using the programme at the counter. Staff become more confident in the offer because they have seen hundreds of positive responses.

As your membership grows, shift your focus from acquisition to engagement. A programme with 500 members where only 100 are active is less valuable than a programme with 200 members where 150 are active. Keep an eye on the ratio of active members (those who have scanned in the last 30 days) to total members. If that ratio is dropping, you have an engagement problem, not a sign-up problem.

The businesses that build the largest and most engaged loyalty programmes are not the ones with the cleverest marketing. They are the ones where every staff member asks every customer every time, where the join process is effortless, where the reward is genuinely motivating, and where the customer feels like they are part of something worth being part of. Get those fundamentals right and the numbers take care of themselves.
