Lunch card for office cafés: filling the gaps
A lunch card for office cafés and workplace restaurants reaches one of the most loyal customer groups in food service: people who work within walking distance Monday through Friday and get hungry between noon and 1 PM every day. The problem isn't frequency—it's the gaps: Friday when people work from home, Monday with leftovers from the weekend, afternoons. Here's the mechanics with sample math, the checkout flow during the lunch rush, and the automations that put the daily special on your guests' lock screens at 10:30 AM.
Visit frequency and ticket size at lunch
The typical lunch guest comes two to four times a week, always in the same time window. The bill runs €8 to €14: daily special, drink, sometimes dessert. The decision happens just before, often as a group: "Where should we go today?"
That decision is your lever. If someone knows at 10:30 AM what you're serving today and still has three stamps until a free meal, they'll pitch you to the group. The paper card can't do that. The wallet card can.
The second quirk: lunch has hard boundaries. Nothing happens after 2 PM, and since remote work became common, Friday—often Monday too—is noticeably slower than Tuesday through Thursday. Filling those gaps is the real job of the card.
Recommended mechanics: 10 stamps, one free lunch
For office cafés, workplace restaurants, and company canteens, we recommend:
- 10 stamps, one stamp per lunch meal €8 and up
- Reward: one daily special free (not the premium dish, not the drink)
- Cooldown: one stamp per guest per day
The sample math:
| Item | Amount |
|---|---|
| Average bill per visit | €11.00 |
| Revenue across 10 stamps | €110.00 |
| Food cost of free daily special | approx. €3.00 |
| Effective discount | approx. 2.7 % |
Just under three percent for a guest who came ten times, usually within a month. And on the eleventh visit, they typically buy a drink and dessert again, which lowers the discount even further in practice.
For high-frequency canteens (daily traffic), 12 stamps can also work because the card still fills in three weeks. The rule of thumb: the card should fill within a month. More on this under How many stamps until reward?.
Rolling out during the lunch rush
Between noon and 1 PM, every second counts at checkout. So setup must happen outside that window:
- QR code along the line. On the menu board, on the wall, at the counter. Guests standing in line have their phone in hand and three minutes to spare. That's the moment to sign up.
- QR code on every table. Seated guests have even more time. A small stand or sticker per table is enough.
- Stamp at checkout. The guest shows the card, the cashier scans with their phone. No stamp pad between tray and card terminal.
- Stamp groups individually. At lunch, people often pay separately, but sometimes one person buys for the group. Rule: each guest with a card gets their stamp if a lunch meal was included for them.
- Launch on a Tuesday. Not Monday, not Friday. Tuesday through Thursday the line is full and the team is in rhythm.
The print-ready stand comes from the system; see QR code stand at checkout. For lunch service, an A3 version for the wall is worth it too.
Automations: the daily special at 10:30 AM
At lunch, there's one moment that decides everything: the half-hour when the office figures out where to eat. The automations target exactly that:
Daily special via push. Around 10:30 AM, a short message: "Today: cheese noodles with salad, €9.50." It lands as a wallet notification on the lock screen of guests who opted in for marketing. It's the most direct path to the lunch decision there is. More on this under Lock screen marketing.
Slow-day booster for Friday. Friday morning: "Extra stamp on every lunch today" or "Friday: free dessert." That brings in some of the guests who'd otherwise eat bread at home and work from home. The same works for Monday.
Win-back. Someone who came three times a week and disappeared for two weeks either changed jobs, is on vacation, or eats elsewhere. A reminder with an extra stamp costs nothing and brings back the travelers and job-switchers.
Birthday. A free lunch on their birthday almost always brings the whole team. That's the cheapest group table you'll get.
Flash deals on leftovers. 1:30 PM, 15 portions left: "Until 2:30 PM: daily special €3 off." Better than the trash.
Geofencing. Guests with the card near the restaurant get a reminder around lunch time. For office cafés in business districts, that's the direct line to people deciding right now.
Common mistakes with lunch cards
- Reward with no limits. "Any dish of your choice" brings the €18 steak. The daily special as reward keeps food cost at three euros.
- No morning message. The daily special at 10:30 AM on the lock screen is the biggest advantage over paper. Without it, you're using only half the power.
- Stamp for drinks alone. An afternoon coffee isn't a lunch. The €8 minimum spend keeps it clean.
- Stand only at checkout. Nobody looks at the checkout while standing in line. The code needs to be along the line and on tables.
- Launch during rush. Starting the card Monday at noon overwhelms the team. Prep in the afternoon, launch Tuesday.
- Cards that are too long. 15 or 20 stamps take two months or more at two visits a week. Ten is the right number.
Takeaway
A lunch card for office cafés and workplace restaurants taps the most loyal customer group in food service and fills the gaps remote work created: 10 stamps from €8 spend, one daily special free, QR code along the line and on tables. The 10:30 AM message with the daily special and the Friday booster do the work nobody has time for before the lunch rush. With stampa, it's free up to 100 active guests and no credit card needed: Create your card now.
