Digital stamp card in Tucumán: one card for several locations
In short: in San Miguel de Tucumán many counter businesses have one shop in the Centro and another in Yerba Buena, and the customer buys at whichever is handy that day. A paper card per shop splits their visits in two and neither reaches the reward. A digital card with one QR per location adds everything to a single account. That's how Giorgini Panetteria, Club Card's first club, has worked since September 2, 2026.
This guide is for bakeries, coffee shops and counter businesses in Tucumán. The examples that aren't Giorgini are hypothetical. For the national context, see the Argentina guide.
Tucumán's problem: one customer, two shops
The Centro and Yerba Buena are only a few kilometers apart, and many people move between the two during the day. They work in the Centro and live in Yerba Buena, or the other way around. For a brand with two locations, that has a direct consequence: the same customer buys at both.
With paper cards, each shop stamps its own. The customer collects five stamps on one and four on the other, and never reaches the reward. On top of that, the owner doesn't know it's the same person. They see two occasional customers where there is one loyal one.
The fix is a single card for the whole brand. The customer scans the QR at the location they're in and the stamp goes to the same account.
The real case: Giorgini Panetteria
Giorgini Panetteria is a bakery in Tucumán with two locations, Centro and Yerba Buena. It launched its club on September 2, 2026 with these rules:
| Rule | Giorgini Panetteria |
|---|---|
| Locations | Centro and Yerba Buena, one QR at each |
| Stamp | One per visit, at most one per member per day |
| Reward | A treat on the house at 8 stamps |
| Card | A single one for both locations |
The rule is short on purpose. The cashier doesn't have to calculate anything: scan and move on. The customer understands the reward without reading fine print. You can see the full Giorgini case.
Why 8 stamps work in a bakery
A bakery has a different frequency from a coffee shop. Many people buy bread several times a week, sometimes daily. If the card asks for too many stamps, the reward feels far away; if it asks for too few, it gets expensive.
With 8 stamps and one per day, a customer who buys three times a week reaches the reward in under three weeks. It's close enough to chase and far enough that the treat doesn't eat the margin. The bakery guide explains how to choose the reward based on your product.
Three hypothetical examples for Tucumán
Bakery with two shops. The same setup as Giorgini: one QR per location, 8 stamps, reward a dozen bread rolls or a sweet item from the house. In the dashboard you see where each member joins and where they come back.
Coffee shop in Yerba Buena with a weekend crowd. Lots of families arrive on Saturday and Sunday. Suggested rule: 6 stamps and a shared afternoon snack as the reward. The frequency is weekly, not daily, so the card has to be shorter.
Takeaway empanada shop in the Centro. Many lunchtime orders from people who work nearby (empanadas are filled pastries, often sold by the dozen). Suggested rule: 10 stamps, reward half a dozen. The one stamp per day limit stops an office's big order from filling the card at once.
| Hypothetical business | Stamps | Reward | Frequency it covers |
|---|---|---|---|
| Bakery with two shops | 8 | A dozen bread rolls or something sweet | Several times a week |
| Weekend coffee shop | 6 | Shared afternoon snack | Once a week |
| Takeaway empanadas | 10 | Half a dozen | Weekday lunchtimes |
What to watch in the dashboard with several locations
With two shops, the dashboard shows things paper never did:
- How many members buy at both locations. If there are many, the single card is doing its job.
- Which location signs up the most new members. That's where the team pitches the club best, and it's worth copying how they do it.
- Who stopped coming. A customer who came every week and hasn't shown up for a month deserves a message, if they agreed to receive one.
The law and the data
If you keep your members' name, email or phone number, Law 25.326 applies. Explain what you use the data for, ask for separate permission for promotions and offer an easy opt out. This is not legal advice.
Other cities in the north and center
Salta is close, but its problem is different: the mix of tourists and locals at the same counter. In Córdoba the difficulty is the university calendar.
