VFD
What is VFD ?
Answer :
A VFD works mostly on cathodoluminescence principle, comparable to a cathode ray tube but at much lower voltages.
A phosphor-coated carbon cathode in each tube of a VFD is blasted by electrons produced by the cathode filament.
What can we know about VFD for pos system customer display ?
Answer :
These display devices combine the benefits of LEDs and LCDs. They provide the same brightness as LEDs but seem to be simpler to read, and they
are able to display numbers, words, or letters for customer display, which are also simple to read in both darkness and light environment in the point
-of-sale.
How long do vacuum fluorescent displays VFD last?
Answer :
The color scheme (which ultimately decides the existence of the phosphor) and display brightness make such a serious influence on the tube’s life
time, which may scope from as little as 1,500 hours for a vibrant red VFD to 30,000 hours for a more common green VFD.

PVC card. There aren’t any exposed parts on the chip or antenna. It is a relatively new technique that has appeared in the world over recent years.
It manages to combine RF identification technology and IC card reader techniques, bringing an end to the matter of passive (no power in the card)
and contact-free cards. A substantial development inside the field of equipment. The card is retained at a specific distance from the reader’s surface
(usually 5-10mm), as well as info is read and recorded through use of radio signal transmission.
