- Same street. Two cafés.
- Same coffee. Same prices.
- One is always full.
- It has a system.
- They tap at the counter. One tap.
- The card is in their wallet. No app.
- Every stamp lands on their lock screen.
- Write to them. Like a text.
- It reaches every card, at no extra cost.
- Next door…
- The barista knows every face. For now.
- Then he leaves. So do the faces.
- Which café do you want to be?
Make my card
Example. Both cafés are made up.



- Two doors. Same street.
- Day one. A sticker on one counter. Café Zawye: Nothing changes. Joe, the barista, knows Rima takes a double espresso with no sugar. Café Sabah: The Kartak sticker goes on the counter. Rima taps it, and the card is in her wallet before her coffee is poured.
- Week three. Joe leaves for Dubai. Café Zawye: Joe leaves for a job in Dubai. The new barista doesn't know Rima, and the coffee Joe used to give her on the house stops. Café Sabah: Joe leaves for Dubai too. Rima's card still has six stamps, and the new barista sees her name when he scans it.
- Week five. A new café opens. Café Zawye: A new café opens across the street with half-price coffee for a month. Rima tries it. Nothing brings her back. Café Sabah: The same new café opens. Rima is four stamps from a free coffee, so she keeps coming.
- Week seven. A slow Tuesday. Café Zawye: A slow Tuesday. The owner posts a story. It is gone by Wednesday, seen by whoever happened to scroll. Café Sabah: A slow Tuesday. The owner writes "Double stamps until noon" and it shows on every customer's lock screen. A few faces from last month are back by eleven.
- Month three. Who knows more? Café Zawye: The owner knows the regulars by face, and not much more. Café Sabah: The owner opens the dashboard: every card, who is one stamp from a reward, and who hasn't been in for three weeks.
- Which door is yours?

Example. Every name here is made up.
Three months later
Café Zawye
- Who the regulars are, if the right barista is on shift
- Not how many come back
- Not who stopped coming
Café Sabah
- 212 customers carry the card
- 38 are one stamp from a reward
- 17 haven't been in for three weeks, and can get a note today
Same street, same coffee. The difference is a shop that knows its regulars after the barista leaves, and can reach them when the street gets busier.
