4 things I got wrong building a QR code tool:
Logos vanished after a refresh (our own security header blocked them)
Mock-up photos that looked pasted on
A pretty animated background slowing every page
Pages that scrolled forever
All fixed. What did you ship and later rip out?
A Halloween poster on a community noticeboard.
Friday: Saturday 19:00, free entry
Saturday night: doors open, pumpkin contest at 20:30
Sunday morning: photos from last night + the next event
Nobody climbed up to swap the poster. The page behind it changed.
Spot the QR codes nobody will scan.
A: by the till, eye level, where the queue stands
B: shop door, ankle height
C: side of a bus at 40 km/h
D: caf茅 table, next to the menu
Two of these won't get scanned. Which two?
A plumber's van, one QR sticker on the side.
08:00: book a visit
18:30: burst pipe? emergency line
Saturday: closed, back Monday
Same van, same sticker all week. He changes the page behind it from his phone when he locks up.
What happens when someone scans a Scanwork QR code:
The print holds one fixed address. Our server looks up where that code points right now, counts the scan (which code, what time), and sends the phone on.
Changing the destination = editing one row. The print never knows.
