Siemens's Industry Automation Division has now redesigned its HF (high frequency) 13.56 megahertz range Simatic RF310R and RF380R RFID (radio frequency identification) read-write devices so that they can also work with ISO 15693 standard transponders (tags). Its ISO 15693 functionality makes the RF300 system also suitable for use in applications which only need simple types of transponders with little memory, such as the inexpensive MDS D100 and D124 ISO 15693 tags. The D324 and D160 tags in the Moby D product line have data capacities ranging from twenty bytes to one kilobyte.
