Техническая документация для ViVOpay Kiosk II (406 Кб) | RF Interference
Test the ViVOpay Kiosk II installation using a test card to perform an end-to-end transaction (the same as an actual purchase on the Kiosk). The kiosk control panel should display “Requesting Authorization”. Even if the transaction is declined (as it should be with a test card), it will prove connectivity all the way through the system. If possible the store manager or some other responsible party should test each card to ensure continued operation and functionality. If the kiosk is rebooted on a regular basis (such as every night) it is important to test the contactless reader as soon as possible afterwards to ensure continued communication to the kiosk.
Refer to the troubleshooting section of this manual before contacting your distributor with support questions.
Q. Why do I need to know about RF interference?
A. Contactless payments use radio frequency technology to send card data to a contactless terminal reader.
Q. How can RF interference affect contactless payments?
A. RF interference can cause data errors. If RF interference is present, contactless payment devices may operation intermittently or inconsistently.
Q. Where does RF interference come from?
A. Radio frequency interference (RFI) can originate from a wide number of sources at the point-of-sale (POS). Some examples of sources of RF energy and RF interference include:
AM/FM radio and TV transmitters
2-way radios, pagers
Power lines, transformers
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.
Q. What RF levels will impact RF operations?
A. Factors that can cause RF interference vary case-by-case. There are no set rules defining a single RF level that will cause RFI. RFI depends on the sensitivity of the equipment under consideration, or how low an interpreting signal can be in the presence of the equipment and cause problems.
Equipment can be particularly sensitive to very low signal levels of one frequency and yet be quite immune to high signal levels of another frequency- so frequency is an important factor.
Some electronic system components are internally shielded and have a very high immunity to interference; but generally, most equipment has not been so engineered.
