Cardboard — POS Mode

On an iPad or a MacBook at a card show, Cardboard flips into a register — build the sale, then take payment, all on the same device. The buyer scans a QR or taps their method and pays right off the screen, no card reader required.

Screen 1Register

The dealer searches or scans cards into the sale from the for-sale grid, then fine-tunes pricing in the cart — including a haggled bundle total — before charging the buyer.

Screen 2Take payment

The screen turns to the buyer, who picks a method from the menu. Tapping a tile expands it into that method’s scan-or-send details — Venmo is shown selected below, but any of the seven works the same way.

Screen 3Billboard

Flip the screen to face outward and it becomes a sign for the table — the seller’s name up top, then a slow, hands-free rotation through what’s for sale: one big card and its price, with a filmstrip of what’s coming up next below. Nothing here is tappable; it just runs while the dealer helps the next customer.

Screen 4Photo source

A phone scan can look rough — glare off the top-loader, an off-angle shot, a cluttered table behind it. When Cardboard has a matching catalog photo, the dealer can switch to that clean, studio-shot image instead — shown here selected, with the original scan kept on file underneath.
