Before the show
Photograph what you are taking, price it, and print a sheet of 15mm stickers. The catalogue downloads to the device, so it is already there when the hall has no signal.
If you do shows
Four weekends a year is a real business.
You do not need a shop to need a till. akard is built for the table you set up on a Saturday morning and pack away that evening.
At the table
Scan a sticker, haggle on the line, take cash or PayNow, hand over the change. Sales queue on the phone and sync themselves when the signal comes back.
After
What you took, what each card really went for, and what is left — without a spreadsheet and without counting the drawer twice.
No card, no clock
Try it on the free tier.
Thirty published cards and the full till, for as long as that fits.
