A photo check, not a final grade. Your original photos are always kept.

Nine-scene walkthrough of the current Go Precheck using one fictional sample card. Riley Hart, Meridian Basketball, the Halo Wave finish, the team, this card, and its photos are all fictional sample data. No camera, network, or account action happens here. This is not a final grade. No value is claimed.

One clear front photo of the fictional sample card. Nothing is sent anywhere.

HOW IT WORKS

1. Scan

Point the camera. The scanner finds the card and captures the original photo, which stays the evidence.

2. Sort

Read what stands out on the card, then swipe it into Keep or Sell.

3. Store

Keep goes to your Vault, where every card holds its photos, its notes, and its batch.

4. Market

Sell turns into a draft listing you review and export yourself. Nothing is ever listed for you, and market context appears only when a licensed source is on.

The walkthrough above uses one fictional physical card and the current Go Precheck flow. It never starts your camera or contacts a provider. Not a final grade.

THE DECISION

Most collectors do the expensive part before the obvious part.

The pile grows, the photos get lost, and the next move turns into guesswork. This usually happens right before you spend money on grading, a listing, or storage. Go Precheck gives every card a next move: keep it or prepare it to sell.

EVIDENCE + TRUST

Honest when the photo isn't enough.

Go Precheck keeps the evidence attached, the uncertainty visible, and the next useful step clear.

When a read needs moreUncertain, slow, incomplete, and failed states

EXACT CARD UNCERTAIN

The read says what is still unknown.

When the exact card cannot be confirmed, Go Precheck asks for the photo that would help most, usually the back.

Add the requested photo

TAKING LONGER

The card stays in your session.

A slow provider does not turn into a made-up result. You can wait, retry, or keep working through the stack.

Wait or retry

EVIDENCE INCOMPLETE

Missing evidence stays visible.

An unassessed area remains unassessed. The report names the limitation and keeps the next photo specific.

Complete the evidence

SCAN FAILED

Failure is a state, not a result.

A failed attempt remains retryable and never becomes a confident identity, condition read, or market statement.

Retry the same scan

Privacy and data handlingVerified facts about the current product

Scope and safetyWhat the visual precheck is designed to support

Go Precheck organizes photo evidence and helps collectors decide what deserves closer inspection.

It does not authenticate cards, issue official grades, guarantee value, or replace a professional grader.
