How Converters Can Make RFID Labels

Adding value to chips

Although converters will never make RFID chips and are unlikely even to design them, they can get involved in them in other ways. There is a market for RFID tags measuring only 2.5 millimeters across. Hitachi Maxell makes such versions by electroplating a tiny coil antenna on the microchip itself. Range is only one millimeter or so. However, this “label” is fitted to the bottom of millions of tiny test tubes every year. These test tubes are used for blood samples and drug research, for example. The global demand for test tubes is several billion yearly and barcodes are rendered unreadable by the attendant moisture, bending, and abrasion.
