RF Interference
Q. Why do I need to know about RF interference?
A. Contactless communication uses radio frequency technology to send phone data to a contactless
terminal reader.
Q. How can RF interference affect contactless communication?
A. RF interference can cause data errors. If RF interference is present, contactless communication
devices may operate intermittently or inconsistently.
Q. Where does RF interference come from?
A. Radio frequency interference (RFI) can originate from a wide number of sources at VAS-related
locations. Some examples of sources of RF energy and RF interference include:
•
AM/FM radio and TV transmitters
•
2-way radios and pagers
•
Mobile telephones
•
Power lines and transformers
•
Medical equipment
•
Microwaves
•
Electromechanical switches
Q. What should I do if I suspect RF interference exists in my environment?
A. Begin by inspecting your environment for possible sources of RF interference.
Q. Do equipment manufacturers test their devices for RF interference?
A. Electronic equipment is tested for RFI sensitivity by the manufacturers. These tests are performed
in a controlled laboratory environment and will often not replicate the types of devices that would be
encountered in your point-of-sale (POS) environment.
