A polycarbonate e-passport (also known as an polycarbonate passport or a PVC passport) is a type of passport that contains a biodata page made of polycarbonate, a strong plastic material, instead of a laminated paper sheet. The polycarbonate layers protect the passport's electronic components and personal data by laser-engraving them into the deeper layers of the plastic data page, which improved the anti-counterfeiting, durability and reliability of the passport compared to the regular laminated biodata page.[1][2][3]
