New technology to increase protection of credit cards

A new technology enabling injecting of unique pieces of data into items made of plastics during a manufacturing process has been developed by the University of Warwick researchers.

The technique, using injection moulding, is believed to increase security of credit cards and other plastic-based products and their protection against counterfeiting.

“We are delighted that we have been able to demonstrate that the technology can embed unique pieces of data in each individual product across a live injection moulding production run,” said Professor Gordon Smith who has led the research.  

“The data can either be made visible to the naked eye or hidden so that it can be read by a low cost ‘black box’ scanner,” he explained.

The technology, suitable for mass-manufacturing of credit cards and other plastic products, uses external force that exploits the polarity of particles and fluids, to selectively influence those particles or a polymer fluid as a product is formed by injection moulding.

“We know this will be of great interest to range of manufacturers seeking to combat counterfeiting in injection moulded products or add security features to credit cards and we will now seek to work with such an interested  company to refine the technology and scale it  up from our own test runs to full blown industrial production,” Professor Smith said.

The University of Warwick based team has recently applied for patents to protect their invention.
