As seen in Cambodia's verify.gov.kh platform, a practical verification method is the QR code. A unique QR code is embedded in the PDF. When scanned, it directs the user to a secure government database where the document's status (valid, revoked, fake) is instantly confirmed. This method is user-friendly and doesn't require specialized software on the user's end, making it highly scalable for public-facing documents. Python scripts can easily generate these QR codes and link them to backend databases.
