A good-looking flyer is only half the job. The real work starts when a customer holds it and thinks "so what now?". A good activating mechanism gives them a clear reason to act right away - or to come back to you later. The three most common candidates are the discount coupon, the QR code and the loyalty card. Each plays toward a different goal, so instead of asking "which is best", ask "which fits my goal".
- Discount coupon - an instant incentive, great for acquisition and the first purchase, easy to measure.
- QR code - a bridge to the online world: website, promotion, sign-up, map; updatable and measurable.
- Loyalty card - builds a long relationship and repeat visits; a reward for staying loyal.
- The choice depends on the goal: acquisition, data and a bridge to online, or keeping the customer.
- The best results come from combining them - a coupon to start, a QR code to sign up, a card for returns.
Discount coupon - the simplest way to say "try it now"
A coupon is understandable to everyone without explanation. The customer sees a concrete benefit, knows what they will get, and has a reason to come in or buy. It is the shortest path from a flyer to the first transaction, which is why a coupon works so well when acquiring new customers and when convincing someone who does not know you yet to give you a first try.
Its big advantage is measurability. If the stub carries a printed promotion code, after the campaign you know how many flyers turned into a real purchase. That is hard data which helps you judge whether a given flyer and a given distribution channel actually pay off.
The secret of the coupon is the expiry date. Without one, the customer puts the flyer aside "for later", which never comes. A sensible, concrete deadline creates gentle pressure and drives action. Coupons work especially well on folded flyers, where you can dedicate a whole panel to a clear stub to cut out or show.
QR code - a bridge to the digital world
A QR code links paper with everything you have online. One scan takes the customer to your website, a specific promotion, a social media profile, a sign-up form or a map with directions. It lets a small flyer open the door to far bigger content that would never fit on paper.
The second advantage is flexibility. Many QR codes can be redirected to a different address at any time, so the same, already printed flyer can lead to one campaign today and another one next month. It is also easy to measure scans, which gives a clear picture of how many people actually reached for their phone.
A QR code has one condition, though: the customer must know why they should scan it. A bare square with no caption is a puzzle that most people simply walk past. Add a short, concrete prompt - "Scan to see the full offer" or "Scan to sign up for updates". And always check that the link truly works and that the landing page looks good on a phone.
Before printing, test the QR code with several different phones and camera apps. Leave some clear space around the code (a safety margin) and do not print it too small - a tiny code can be unreadable, especially in poor light.
Loyalty card - playing for returns
A coupon and a QR code act here and now. A loyalty card plays the longer game - it builds a relationship and makes the customer come back. The classic stamp or points mechanic is simple: a few visits, then a reward for loyalty. It is a subtle but effective reminder to choose you again next time.
This mechanism works best where customers return by nature: in hospitality, services and retail with repeat purchases. A cafe, a car wash, a salon, a takeaway spot - everywhere a card turns a one-off guest into a regular, and each visit brings them closer to the reward.
A loyalty card is also a physical object the customer carries and regularly sees in their wallet. It is a free reminder of your brand, returning every time they reach for another card. That is why it pays to make it durable and neatly finished - a worn, bent card ruins the impression you care about. A ready format is the 85 × 55 mm client card with rounded corners, on heavier stock and with a film that protects it from scuffing.
Which to choose? Start with the goal, not the trendy solution
There is no single winner - there is a match to what you want to achieve. Instead of picking a mechanism because "everyone has QR codes", step back and name your goal. Then the choice becomes obvious.
- You want to acquire new customers and prompt a first purchase - go for a coupon. An instant benefit and a deadline do the job.
- You want to build a bridge to online and get to know the customer - choose a QR code. It leads to your website, to sign-ups, and gives a measurable signal of interest.
- You want customers to return and buy more often - reach for a loyalty card. It rewards loyalty and builds a habit.
If you sell a voucher or a gift card, the mechanic can be different again - there the key is the value of the gift and the ease of handing it over. We cover how to design such a document in our piece on designing a voucher that catches attention, and ready-made vouchers and gift cards can be ordered in a form that fits your brand.
The best result? Combine the mechanisms into one path
These three tools are not rivals - they complement each other beautifully. You can design one flyer that guides the customer step by step: a coupon to start convinces the first purchase, a QR code invites a newsletter sign-up or a follow, and a loyalty card gives a reason to return. One piece of paper, three different moments of contact.
The important thing is not to overwhelm the reader. If you throw everything in at once with no hierarchy, the flyer turns into chaos. Set one main goal in a prominent place, and treat the rest as support. A clear layout, one strong call to action and calm around it - that always beats clutter.
A flyer is not decoration but an invitation to act. An activating mechanism is that invitation spoken out loud.
Design that makes the mechanism work
Even the best idea fails if the customer does not grasp it in a few seconds. That is why the promotion condition and the deadline must be legible, not hidden in fine print at the bottom. Say plainly what the customer gets, by when, and what to do. A clear call to action is the heart of the whole flyer.
Make room for what is meant to be filled in or shown. A coupon needs a clear stub with a code, a loyalty card - fields for stamps or points, a QR code - clear space around it and a caption. If you want to dig deeper into layout and copy, see our guide on designing a clear flyer that encourages action.
Finally, print quality. A card the customer carries for weeks must be durable. A coupon someone cuts out should have a clear line and a legible code. A QR code printed sharply and at a sensible size will scan on the first try. Solid production makes the mechanism not only look good but simply work.
Plan measurement before you print. Give coupons a separate promotion code for each campaign and each channel, enable scan statistics for QR codes, and for loyalty cards note how many customers complete them. Without that it is hard to tell which mechanism truly pays off.
Summary
The coupon, the QR code and the loyalty card are three different answers to the question "what next?". A coupon attracts newcomers and closes the first purchase, a QR code links paper with online and provides data, and a loyalty card brings customers back. Start with the goal, pick the mechanism, and if you want the maximum effect - combine them into one thoughtful path. Good design and solid printing will do the rest. For the right format, take a look at our folded flyers, which have room for everything you need.
