E-paper price tags for slabs and one-touches
Cardstock clips to a slab or a one-touch. Scan the card once. It works out what the card is, prices it from what cards like it actually sold for, and pushes the number to the tag. When the market moves, every tag in the case moves with it.
Dynamic electronic pricing at your fingertips
You price a case on Sunday night. By Thursday a rookie has gone off, a set has been reprinted, and half your labels are wrong in one direction or the other. The only way to find out is to pull every card and start again.
A card runs while it sits in your case and the sticker never notices. The buyer who checked their phone does.
Nobody tells you it is too high. They walk past, and you find out on Sunday when it is still there.
Two hundred cards, a price guide open on a laptop, a sheet of blank labels and a marker. Every single week.
01 Scan
The camera reads the card, then checks what it read against a catalogue of fifteen million. Sports and non-sports, graded and raw. It knows a PSA slab from a one-touch, tells a 2017 printing from a 2003 one bearing the same name, and finds a card by its artist when the set symbol will never scan.
It waits for a frame that is genuinely sharp rather than taking the first one, so what it reads is what is printed.
02 Price
Real transactions, including best offers. A card listed at $400 and sold at $340 is a $340 comp, and most sources will tell you $400.
Broken out Near Mint through Damaged, with the number of listings behind each rung so you can see when a comp is thin. Tap a rung and the price follows it, on the phone and on the tag.
It looks at the card, not just the name
Centering is geometry, and geometry is something a camera is genuinely good at. Cardstock finds the printed border on all four sides and measures it to a hundredth of a millimetre, then tells you 55/45 or 70/30 the way a grader would.
It measures corner rounding as a real radius. It finds edge whitening as contrast against the border. Then it puts the card on the condition ladder and shows you exactly why it landed there.
Surface is not assessed, because a scratch needs light at a low angle and no phone has that. You get two of the four things a grader weighs, said plainly, and never a predicted grade.
03 Push
Price on the left panel. On the right, whatever the slab label does not already tell you: population for a graded card, the parallel and condition for a raw one. Repeating the player name would waste the only space there is.
E-paper draws no power until something changes, so a coin cell runs a tag for months and the price stays readable under any light in the hall. Change a price in the app and the tag has it before you have put the phone down.
It fits a one-touch as well as a slab. The same tag takes a graded holder or a raw card in a magnetic case, so the whole case runs on one thing rather than tags for the slabs and stickers for everything else.
A tag pairs to your phone and refuses everyone else, so the dealer at the next table cannot write to your case by accident or otherwise.
The same tag on a one-touch
Inventory
Every card you scan lands in a list you can sort by player, year, set or price. Raw and graded kept apart, because they are different markets and mixing them blunts both.
A card priced well under its comp is flagged, amber at 15 percent under and orange at 30. That is money you were leaving on the table, in a column, without going looking for it.
Mark one sold and the tag frees itself for the next card.
Every price guide reports online sales: shipped, fee-bearing, listed and waited on. A card sold across a table is a different market. Cash, no fees, and a price arrived at by conversation.
Nobody tracks that market, because nobody is standing at the table when it happens. Cardstock is. Mark a card sold and the sale becomes a comp, yours first, and over time a picture of what cards really go for in person.
It also learns what you give away. If you take 18 percent off asking on average, that is worth knowing before a show rather than after.
Every one of those is a comp nobody else recorded.
Cardstock is being built, not sold. This is the honest state of it and it will be kept current.
