Transparent Window PC Cards are high-security polycarbonate cards manufactured via adhesive-free thermal fusion lamination. An integrated transparent polycarbonate viewing window is embedded into the card body during layer pressing. The transparent window enables optical anti-counterfeiting, portrait display and visual verification. Combined with subsurface laser engraving, encrypted smart chips and multi-layer security patterns, they are widely used for official identity documents, secure ID badges, high-grade membership cards and access credentials. Compliant with ISO/IEC 7810 ID-1 standard (85.5mm × 54mm).
