What is an RF scanner?
An RF scanner is a Radio Frequency Scanner. In a warehouse setting this is a wireless handheld device that uses a radio frequency wireless network to communicate with a Warehouse Management System (WMS) in order to transfer information throughout the network. Typically RF scanners are used in warehouses to pick products.
What is radio frequency (RF)?
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 3 kHz to around 300 GHz.
How does a radio-frequency identification system work?
A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.
What is rfrf and how does it work?
RF current can easily ionize air, creating a conductive path through it. This property is exploited by “high frequency” units used in electric arc welding, which use currents at higher frequencies than power distribution uses.
What is radiofrequency (RF radiation)?
Radiofrequency (RF radiation is nonionizing electromagnetic energy characterized by relatively long wavelength, low frequency, and low photon energy. RF radiation is usually described by its frequency, expressed in hertz. The RF part of the electromagnetic spectrum extends from 30 kilohertz (kHz) to 300 gigahertz (GHz).
What is the resolution of an AUTOFEED photo scanner?
Autofeed photo scanners will differ in the resolution that they can achieve when scanning a photo or document. Photo scanner resolution will be given in dpi (dots per inch), and you can typically select from between 300 dots per inch (dpi), 600 dpi, or even 1200 or 2400 dpi.
What is the best way to scan documents?
OCR: One very useful feature for scanning documents is Optical Character Recognition (= OCR) editing software. This allows you to scan a Word or Excel document, and be able to search text strings on the scanned document. Duplex scanning: Many times, people write the date and other background information on the back of a photo.
