NOTICE
The local dose rate at a defined distance specified on the nameplate is based on a worst-case
estimation if switched off,
‣
outside the path of the beam and takes into account production dependent fluctuations of the
source activity and tolerances of the measuring devices. Therefore it may be slightly different
from the local dose rate which has been calculated from the specified attenuation
factors.→  11
RFID TAG Operating principle of RFID and NFC
Radio frequency identification (RFID) makes it possible to identify the measuring point without
direct visual contact, and exchanges data between suitable terminal devices. A transponder consists
of a microchip, an antenna and a carrier/housing. The digital information is saved in the microchip.
Energy is supplied to the microchip during the communication process by the electromagnetic field
initiated by the transmitter.
Near field communication (NFC) is an extension of RFID technology and is an international
communication standard for wireless data transfer at a frequency of 13.56 MHz. The external power
supply and safety standards only allow a short range with a maximum data transmission rate of 423
kBit/s and a connection setup of <0.1 s. The latest NFC technology can be used with NFC-enabled
devices.
Passive NFC transponders do not have their own power source (e.g. batteries) and are therefore
maintenance-free. They are powered by the electromagnetic field of the transmitter.
