Point-of-sale for card-show vendors

The point-of-sale built for the trade table.

KOmpare is a POS for Pokémon card vendors at card shows. Scan a stack with your camera and price it with the customer watching the math — TCGplayer-based market prices, your buy % and the cash to balance on one screen, so you both get to "deal" without a five-minute lookup. Works offline, so dead venue Wi-Fi doesn't kill the trade.

The pricing problem

Customers don't trust prices
they can't see.

Quote a number and the buyer's already pulling up prices on their phone to argue with you. KOmpare shows the TCGplayer-based market price for the card's condition — and how old that price is — on a screen you can turn around. Pick the price, show where it came from, and move on to the next card.

One market price per condition, ready offline.

TCGplayer-based market prices for every condition from Near Mint to Damaged, kept on the phone from your last sync. Tap the condition, the price follows — no swapping apps, no losing the customer's attention.

Know whether the price is from today or last week.

Every price shows how old it is — "3h ago" — with the exact date and time underneath. You decide whether to use it; the customer sees the same thing you do.

When you already know the number, just type it.

Type your own price, or look up recent eBay sales from inside the app and enter the sold price yourself. Your default buy and sell percentages apply automatically.

How a trade runs

Card in hand to cash in hand, without leaving the app.

Every step is built for the speed of someone standing at your table with a stack and a question.

1

Scan it or search it.

Point the camera at a Pokémon card and KOmpare recognizes it on your phone — nothing to upload. Or search the on-device catalog: English and Japanese sets, sealed product included.

2

Pick the price you can defend.

Confirm the condition and the market price for it comes up with its age. Your buy % does the rest — or type a custom price when you already know the number.

3

Settle up without doing the math.

Cards on your side, cards on theirs. Cash to balance is calculated for you, and the buy % updates live so you know what the deal really looks like before you shake on it.

The booth problem

The venue Wi-Fi always dies during the biggest trade of the day.

  • Zero bars, trade still closes. The full catalog (cards, sets, sealed) lives on the device, and prices stay ready from your last sync. Search, pick a price, balance and complete the trade offline — it syncs the moment you're back online.
  • Customer changes the deal mid-trade. They swap a card, ask for a little more cash, drop a sealed box in last second. Adjust the line and the buy % and totals update instantly. No restarting, no recalculating in your head.
  • Both sides of the table see the same numbers. Vendor total, customer total, buy % and the source behind every price are right there on the screen. Nobody is doing trust-math in their head.
  • Trade history on every device. Every completed trade is saved and synced across your devices. Pull it up days later when the customer comes back wanting to talk again.
