Point-of-sale for card-show vendors

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

KOmpare is a POS for vendors who buy and sell cards at card shows. Price a stack of cards in seconds with the customer watching the math — comps from every source you care about on the same screen, and a running buy-% so you both get to "deal" without a five-minute lookup. Offline-capable, so dead venue Wi-Fi doesn't kill the trade.

The pricing problem

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

Quote TCGplayer Market and the buyer's already opened eBay on their phone to argue with you. KOmpare puts every comp you care about — TCG benchmarks, recent eBay sold averages, PSA 9/10 — on the same screen. Pick the number, point at the row it came from, and move on to the next card.

Use this price

Stop tab-juggling four price sites mid-trade.

TCGplayer Low / Mid / Market / High, eBay 7-day and 30-day sold averages, and PSA 9 / 10 sold comps when they're available — all on one sheet. No swapping apps, no losing the customer's attention.

Know whether the comp is from now or yesterday.

Every row shows when it was last fetched — white inside half an hour, amber by two, red past that. You decide whether to use it or refresh; the customer sees the same signal you do.

When you already know the number, just type it.

Tap Custom, type your price, done. The original sources stay one tap away if the customer wants to check your work.

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

Find it without fumbling.

Search the on-device catalog — every Pokémon set, sealed product included. No tab-switching to a browser, no "loading…" while the customer waits. The catalog lives on the phone.

2

Pick the comp you can defend.

Confirm condition, pick the source. The price that goes on the trade is the one you tapped — and the row it came from is one tap away if the customer wants to see it.

3

Settle up without doing the math.

Cards on your side, cards on theirs. Cash to balance lands automatically. 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 uploads 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 that sticks around. Every completed trade is locked and synced. Pull it up days later when the customer comes back wanting to talk again.
