TAG Card Vision

Use the Surface Defect Transparency Slider in order to view the card using TAG's Card Vision. Card Vision enables you to more easily spot defects and imperfections in the card by utilizing TAG's Photometric Stereoscopic Imaging technology. This advanced imaging feature is included with both TAG_X and TAG_S service levels.

DIG Reports

Digital Image & Grading (DIG) Reports are the most comprehensive and detailed condition analysis and technological grading available. DIGs can be accessed by scanning the QR code on the tag or by looking up the card's Cert number. TAG_X DIGs focus on the core defects that impacted the grade, aka the "DINGS." TAG_S DIG Reports breakdown the card into further detail with precise 3 digit scoring.
