BIS M uses the high frequency (HF) 13.56 MHz and supports the standard either according to DIN ISO 15693 and/or DIN ISO 14443. Due to the large variety of passive data carriers in terms of dimensions, design, memory size, operating temperature, material, antenna technology, installation and range, you can implement almost any technical task in an application-optimized manner. BIS M is the robust system with absolute data security.
