Quickly search by entering the certificate serial number from the ISA label, or scan the QR code on an ISA graded trading card. When a matching certification record is found, the app displays available card details such as year, set, parallel or variation information, card number, player or character name, authenticated date, assigned grade, grade label, and population information for that grade when available.
