Whether it's CD packaging, containers or identification cards: RFID tags (Radio Frequency Identification) are increasingly finding their way into everyday life. They make it possible to label objects or goods and identify them automatically by radio frequency. The appropriate scanner can read and process the data contained in the label. 'Smart labels' can be affixed to goods under production conditions of up to 100 degrees Celsius. But at higher temperatures - such as with laser fusion - they fall apart: the metal components are being manufactured out of stainless steel powder, using a laser at temperatures in excess of 1400 degrees Celsius. Such production conditions precluded the use of radio-based identification - until now...
