From smart electric meters to tachometers, wherever consumption or mileage is read out electronically, the data transmitted should not be open to manipulation. That is especially true for verification of payment transfers made via credit card. Researchers at the Fraunhofer Institute for Photonic Microsystems IPMS have developed a solution that makes it possible to configure the functions of security elements to address this issue after manufacturing, reliably and cost-effectively providing them with multidimensional protection.
