For phone repair shops
The counter stays clear.
Walk-ins scan a code at the door, say what’s wrong and wait wherever they like. Their phone tells them when you’re ready for them — and you can see what’s coming before they reach you.
The counter
A queue of people with broken phones.
- Walk-ins arrive while you’re mid-repair, and wait at the counter to be seen.
- “How long will it be?” gets asked before you’ve even looked at the phone.
- Somebody counts the people ahead of them and takes the repair down the road.
None of that is a repair problem. It’s a waiting problem — and it’s the part a customer remembers.
Say what’s wrong, then wander off.
A code on the door opens a page in their browser. They tell you what’s wrong and which phone, take a number, and wait wherever they like.
