Scanner
An electronic device used to scan barcode symbols and produce a
digitized pattern that corresponds to the bars and spaces of the
symbol. Its three main components are:
• Light source (laser or photoelectric cell) - illuminates a barcode.
• Photodetector - registers the difference in reflected light (more
light reflected from spaces).
• Signal conditioning circuit - transforms optical detector output
into a digitized bar pattern.
SDK
Software Development Kit.
Symbology
The structural rules and conventions for representing data within a
particular barcode type (e.g. UPC/EAN, Code 39, PDF417, etc.).
USB
Universal Serial Bus. Type of serial bus that allows peripheral devices
(disks, modems, printers, digitizers, data gloves, etc.) to be easily
connected to a computer. A "plug-and-play" interface, it allows a
device to be added without an adapter card and without rebooting
the computer (the latter is known as hot-plugging). The USB
standard, developed by several major computer and
telecommunications companies, supports data-transfer speeds up
to 12 megabits per second, multiple data streams, and up to 127
peripherals.
WLAN
A Wireless Local Area Network links devices via a wireless
distribution method (typically spread-spectrum or OFDM radio), and
usually provides a connection through an access point to the wider
