3.5.3 EMC effects from magnetic fields

Since in this type of RFID-Technology the communication between the reader and transponder
takes place by modulation of a magnetic field, alternating magnetic fields in the vicinity of the an-
tenna can have a negative impact on its function.
Sources of such magnetic interference fields include coils within a primary or secondary switching
power supply.
When determining the position of the reader and antenna within a device, check the device for any
possible sources of interference as described above. If necessary, use shielding to suppress such
interference.
