What Makes a Document ‘Tamper-Proof’? Uniprint Global Explains

Categorised in: Blog

Your financial institution, telecom provider, logistics company, or government department might move sensitive documents across cities, borders, or digital workflows, which comes with serious security concerns. Your information needs to remain confidential, traceable, and unaltered from sender to recipient, and tamper-proof documents can help give you peace of mind. 

Here’s what actually goes into making a document tamper-proof and why that matters in a South African business context.

Tamper-Proof Means Tamper-Evident

A truly tamper-proof document doesn’t just prevent interference, but it’s also designed to clearly reveal if someone has tried to alter it. Think of South Africa’s prepaid electricity vouchers, for example. If a code has been scratched off and reprinted, it’s often immediately obvious to the eye because the tamper evidence is built into the design. The same principle applies to more secure documents like bank-issued PIN mailers or sealed delivery records.

At Uniprint Global, we can use numbered security seals with unique security codes. These seals are part of a highly controlled printing and fulfilment process that allows each item to be traced from production through to final delivery. If a seal is broken or mismatched, it’s an immediate red flag.

Concealing Sensitive Information

Another common tamper-proof technique we employ is a peel-back concealment feature. This is often used by financial institutions when mailing PIN numbers to clients. The PIN is digitally printed under strict conditions and concealed beneath a protective layer that can only be peeled away once. If it’s been tampered with, it can’t be resealed without leaving visible signs of interference. 

Secure Design Starts at the Print Stage

From the ink used to the layout of the information, every element of your document can be configured to reduce fraud. For example, microtext printing can be used on secure vouchers or access credentials and heat-sensitive inks that fade or change colour when touched can also be applied to certain high-risk documents like cheques or utility rebates.

Uniprint Global’s secure print environments have tight protocols to manage these features. Our printing facilities don’t just meet global standards but also meet the real-world demands of our South African clients, where loss of trust can lead to reputational and financial damage.

Choosing a print partner who understands the stakes is critical. Uniprint Global’s tamper-proof systems are designed to work with the speed and complexity of your industry without cutting corners on security, traceability and trust.
