How it works

One scan does it all.

Identify the card, pull the dated market price, apply your rules, print the label — and keep every label repriceable forever. Here's the whole loop, step by step.

06Reprice

Reprint stale labels

Step 01Scan the card.

Point your phone at the card. Slabfactor identifies it — name, set, number, variation — in about a second. No laptop, no lookup tab, no typing a card name with a line at the table.

Step 02Pull the market price.

The card's current market price comes back from a trusted source like TCGplayer, stamped with the date it was pulled. Not what it went for whenever the case was last labeled — what it's going for now. Prices refresh nightly.

Step 03Apply your rules.

Your margin logic runs on top: round to the dollar, hold a floor, ask your percent of market. Set it once and every card after it is priced your way, automatically. Any card can still be overridden by hand.

Step 04Print the label.

A compact label prints on the spot: the card's identity, the dated market price, your ask, and a QR code. It sticks to a penny sleeve, a toploader, or a slab — and it replaces the handwriting nobody has time to redo.

Step 05Let the QR do the talking.

A buyer scans the label and lands on the card's live page — today's market price plus direct links to the card on TCGplayer and eBay. The sticker stops being your word against their phone; the price argues for itself.

Step 06Reprice without rescanning.

Every scan built your inventory as a side effect. When the market moves, Slabfactor knows exactly which labels drifted — reprint the stale ones as a batch. The cards never leave the case.

The label

Four things on every sticker.

Each one is there for a reason — together they make a label both sides of the table can trust.

Works with the printer already on your table.

Slabfactor is built for the cheap Bluetooth thermal printers dealers already own — the Niimbot D110 / Phomemo D30 / Nelko P21 class that's standard at show tables as of August 2026. Labels today are cut for the Nelko P21; support for the wider class is on the map. No printer brand is a partner or a sponsor — they're just the hardware on the tables.
