A juice bar in a Belgian chain, open for years, had a 3.6 Google rating. Six weeks after the Lecy tag was placed at the till, its rating is 4.2 and 272 customers have joined its loyalty programme, with no app, no card and not one extra gesture for the team. No fresh start here: an established shop, with its regulars, its stamp card and a rating built over the years. That is what makes the result worth a look.
Updated on 20 October 2026 with the six-week figures. First version, 25 September: 4.1 on Google and 162 sign-ups, at three weeks.
The starting point: an established shop
A Google rating is built over the years, and the more reviews a listing has, the more slowly its average moves. This shop had everything of an established address: regulars, a paper stamp card, and 3.6 on Google.
Three weeks, then six
After three weeks, 162 customers had joined the programme, one by one, at the till: they had held their phone to the tag while paying, opened the link, and their point had been added. The Google rating had gone from 3.6 to 4.1. By mid-October, six weeks after the tag went in, the shop has 272 sign-ups and a 4.2 rating. The rise continues, more slowly: a rating has inertia.
The mechanism is the same everywhere. After their point, the customer can say how it went: that feedback reaches the shop in private, in its back office, to help it improve. They can also leave a Google review in one tap, right after being served. No more sign at the till, no more asking by the team: the invitation arrives at the right moment, on the customer's phone. Lecy never writes or buys a review; the customer writes what they want, under their own name, or nothing.
“I find this system very practical, no more losing paper cards. Your juices are excellent.”

For the team: nothing more to do
The tag sits next to the till. The team does not add points: the customer holds up their phone while the payment goes through. The paper card is being phased out gently: no new cards from the end of September, stamps still accepted until the end of the year, and a customer who already has a card gets their stamps back as points. The customers are happy, and so are the teams.
Why an established shop is the real test
- Habits already exist. Regulars have their card and their ritual; the tap had to win its place next to them. 272 sign-ups in six weeks.
- The rating has inertia. On an older listing, gaining half a point takes recent, regular reviews, not a one-off burst.
- The team has its routines. A tool that asks them for one more gesture does not last. This one asks for none.
Another case study, a Parisian house launched on its opening day, showed what the tag does for a brand-new listing. This one shows it moves an older listing too.
Frequently asked questions
Do you need a new shop for the rating to move?
No. This shop had been open for years, at 3.6 on Google. Three weeks after the tag went in, it was at 4.1; six weeks after, at 4.2.
What happens to the regulars' stamp cards?
Here, no new cards from the end of September; stamps are still accepted until the end of the year, and a customer who has a card gets their stamps back as points. Each shop sets its own timetable.
Does the team have to ask for reviews?
No. The invitation arrives on the customer's phone, after their point, right after they have been served. They leave a review if they want to, or nothing.
