The Decodability Edge Grade cards are offered in Grades A,B,C,D,F (4,3,2,1,0) of decodability edge type defects for use in testing bar code verifiers. To achieve a edge decodability defect , a single edge within a character has been moved along the entire edge (from top to bottom). The precision of this alteration causes the defect grade to be the same no matter which scan path is used to scan the symbol. Each card is individually serialized, major values are marked on the card, and all values are included in a written report.
