The birth certificates we sell our clients come with the following security features depending on your country Intaglio Printing: Fine-line engraving and printing techniques create a three-dimensional effect and make it difficult to replicate or alter the document. Microprinting: Tiny, closely spaced letters and numbers are incorporated into the design of the certificate, making it difficult to duplicate or forge. Ultraviolet (UV) Ink: Hidden UV ink is included in the design of the certificate and is only visible under a UV light, providing an additional layer of security. Watermark: A subtle watermark is included in the design of the certificate, which is visible when the document is held up to the light, providing another layer of security. Tamper-resistant Lamination: The certificate is laminated to protect it from wear and tear, as well as to prevent unauthorized alteration or duplication. Holograms: Holograms are often used on certificates and documents to add an extra layer of security and prevent counterfeiting. Barcodes or QR Codes: Barcodes or QR codes can be added to the certificate to track its authenticity and prevent unauthorized duplication.
