What is a card show POS?
A card show POS is a point-of-sale system built for running a table: pricing individual cards on the spot, taking payment, and tracking what came in and went out for the day. It is the same job any retail POS does, ring up what a customer owes and log the transaction, just applied to a vendor working a table instead of a fixed storefront.
A card-specific POS adds what a generic checkout cannot: it needs to price thousands of individual cards instantly instead of ringing up a small, fixed catalog of items, and it needs to handle buys and trades from customers, not just sales to them. Vendor Hub does that by comping every card against live market data and applying your own buy and trade percentages automatically, so pricing a stack at the table takes seconds instead of manual lookups.
How Vendor Hub works at a show
- 1
Scan a card or slab
Point the scanner at a single card or a whole stack, raw or graded. Vendor Hub reads it straight into the deal instead of you looking it up by hand.
- 2
Get a live comp
Every card comes back comped from live Double Holo marketplace sales data in seconds, no thumbing through sold listings while a customer waits.
- 3
Your percentages apply automatically
Your own buy and trade percentages are already applied to the comp, and you can edit them mid-deal. The number on screen is the number you can quote.
- 4
Review the whole deal
Totals stay live as cards get added to or dropped from the stack, and you get a full review before anything is final. Nothing commits until you say so.
- 5
Confirm and it's logged
Once you confirm, the deal lands in your books automatically, including table fees, expenses, cash in, and cash out for the show.
- 6
Check profit per show
Every buy, sell, and trade from the show rolls into a per-show profit and loss number, so you know how the weekend went without reconstructing it from memory.
