Loyalty card: cardboard or digital
The cardboard loyalty card has worked for decades and there is nothing to apologise for in using one. The question is not whether it is outdated, but what you lose with it and whether that matters to you. For some businesses the answer is almost nothing. For others, it is half the customers who had decided to come back. This guide compares the two options by what they cost and what they return.
What cardboard does well
It needs no explanation, costs pennies, and does not depend on the customer having battery. It can be printed in an afternoon at any online printer and, if the design is nice, people keep it and show it. For a business that has just opened and wants to test whether the idea sticks, cardboard is a reasonable way to start: within a month you know whether your customers respond to a reward for repeating. No digital tool will make a badly designed programme work, so testing on cardboard before paying a subscription makes sense.
What gets lost along the way
A large share of the cardboard cards handed out never come back, and not because the customer did not want to. They end up in a coat, in the car, in another wallet. Each one is someone who said yes and whom you stop counting. The second problem is that cardboard is mute: you do not know how many people are one stamp from the reward, you cannot tell them, and it leaves you no list when the programme ends. The third is the stamp itself, which any pen can fake, forcing you to choose between trusting and watching.
What changes with a pass on the phone
A pass in Apple or Google Wallet is the same card, but it lives in the wallet the customer already carries, next to the transport pass. It is added by scanning a code at the counter, with no download and no account. From then on it does not get lost, it updates itself when you add a stamp, and it lets you send a notice to the lock screen when one stamp is missing for the reward. And it leaves you a list of customers who decided to come back, which is yours and is the most valuable thing the programme produces. What does not change is the work of offering it at checkout.
What each one costs
Cardboard costs between five and fifteen cents per printed card, plus the stamp, plus the time to restock. A digital pass service usually costs between twenty and thirty euros a month per location. The fair comparison is not that one, it is how many redeemed rewards each produces. If with cardboard one in four cards handed out gets redeemed and with the pass one in two does, the pass has doubled the number of customers who made it back ten times. With an average ticket of three euros, that covers the fee with a handful of extra regulars a month.
How to decide
Stay on cardboard if you have just opened, if most of your customers are passing trade, or if you still do not know what threshold to set. Move to a digital pass once you know the idea works and want to stop losing the cards that stay in coats, when you want to be able to tell whoever is one stamp away, or when you run more than one shift and need stamping not to depend on who is in. And if you switch, do it in one go and with the same rules: a cardboard card that can be transferred to the phone at the counter means nobody feels they have lost what they had built up.
