1. The Common Challenge with Dual-Sided ID Cards
Whether applying for a mortgage, opening a corporate bank account, or submitting visa documentation, government and financial institutions almost universally demand a copy of your national identity card, driving license, or citizenship certificate with both front and back sides displayed on a single page.
Submitting two separate image files often leads to immediate rejection by automated document ingestion portals. On the other hand, attempting to manually paste two smartphone photos into a word processing document frequently results in stretched proportions, distorted text, and blurry micro-printing.
2. Understanding ISO/IEC 7810 ID-1 Standards
Virtually all modern national identity cards, driver's licenses, and residence permits follow the international ID-1 standard:
- Physical Dimensions: 85.60 mm wide × 53.98 mm high (3.370 × 2.125 inches).
- Corner Radius: 3.18 mm rounded corners.
- Aspect Ratio: 1.586:1.
When printed at 100% scale on a standard A4 sheet (210 × 297 mm), the front card sits squarely in the top half, while the back card sits aligned in the lower half with clear margin boundaries.
