CROC-Security Seals / Issuance

An essential element in the production of secure documents is the actual step of issuance. The CROC-system offers the possibility to segregate the last phase from the previous, making the system more robust against unauthorized document production and issuance.

For the CROC-system each security feature and each investment must perform to its maximum. During the issuance process a security seal is applied by the authorized officer.

Compared to traditional dry or wet-stamps this CROC-Security Seal contributes strongly to the overall security. For one it is a uniquely identified, numbered element offering a full audit trail and should be stored separately from any other systems component.

For two, it adds to the overall security of the document and the personalization. Due to the translucent make, it can be applied late in the process and protect key data. As such it exceeds any pre-applied element in its functionality.


"Security-printer in-a-box": The security seals come in practical dispenser-boxes and are applied without any carrier to the document.
