BIS C works with low frequency (LF) and uses two frequencies: 455 kHz for writing and 70 kHz for reading. The wide variety of passive data carriers in terms of dimensions, design, memory size, operating temperature, material, assembly and range means that you can implement almost any technical task in an application-optimized manner. BIS C is established as the standard for tool identification.
