Peratech Ltd has developed switches which the company claims can overcome the risks of "contactless skimming" in security cards. Based on its patented Quantum Tunnelling Composites (QTCs) material, Peratech says that by embedding these into RFID chips used in contactless cards and passports, it ensures that they can only be read in a secure manner by the user pressing on the switch.

"Peratech has been working on the QTC composite and the polymer based variable resistor switch for some time, and has now made switches 30µm thick, thin enough to be laminated inside the current generation of RFIDs used in access or security cards and passports," said Taysom.

Is this the answer to security cards' risks? Discuss…
