Shirts and signs.

Every surface gets its own code so we can see which one actually gets scanned. Big type does the work from across the room; the code does it from three feet.

T-shirt, front

SINGLE.

Print area about 10 by 12 inches. Code at least 3 inches wide: fabric print is low-contrast, so use error-correction level H and keep the white quiet zone around it.

T-shirt, back

Her friends are hiring.

Serious inquiries only (be funny)

For the friends’ shirts. The front says "I’m the committee."

No experience required · must be nice to dogs

datecaitlin.app

Letter or A3 for tables and windows; poster size for events. Code 4 inches or larger so it scans from a few feet away.

Sticker or coaster

apply ♥

Laptops, bar coasters, the bathroom mirror at the party. Cheap, and the easiest to hand to someone.

The site records the tag with each application, and nothing else about the visitor.
Test every code with an iPhone camera from three feet before printing a hundred of anything.
