Measured by machine. Confirmed by a grader. Provable by anyone.

Every card is photographed front and back at high resolution under controlled lighting. AI software then measures what drives a grade: border ratios for centering, the shape of each corner, wear along each edge and flaws on the surface. [[Add hardware and resolution specs once the grading rig is chosen.]]

Measurements are only half the job. A trained AIM grader reviews every card's images and measurements, checks for alterations and confirms the final grade. Their sign-off is recorded with the certificate.

Every AIM slab contains an NTAG 424 DNA chip made by NXP. Each tap creates a new encrypted one-time code, and our server checks it instantly. The chip's secret keys can't be read out, so it can't be cloned. Buying a slab? Tap it twice: a genuine chip passes both times, each time with a fresh code.

Works with iPhone XS or newer and Android phones with NFC turned on. No app needed.

When your grade is confirmed, the certificate (card details, grade, subgrades and fingerprints of the original images) is written to Hedera, a public ledger governed by a council of global enterprises.

Once written, an entry can't be altered, not even by AIM. If a grade is revised after a review, the change is added as a new entry, so the full history stays visible.

The public record holds card details, grades and image fingerprints only. Your name, address, order and declared values are never published.

Every certificate page links to its public entry. Download the original images and compare their SHA-256 fingerprints with the public record. You don't have to take our word for it.
