It has been over 30 years ago that the first barcode scanner was introduced and utilized commercially. since then they have proven their value in automating workflow in retail, healthcare, industrial and municipal applications. A barcode scanner is an electronic device for reading printed barcodes and is designed to enable data management for multiple inventory items in an efficient and simplified manner. It consists of a light source, a lens and a light sensor which translates optical impulses into electrical ones.
There are many types of scanners available with a wide range of features. there is Pen-type readers where barcode data is being manually dragged across the barcode, laser scanners which work the same way as pen type readers except that it uses a laser beam as light source, and CCD readers which make use an array of hundreds of tiny light sensors lined up in a row in the head of the reader. there are 2D barcodes which are optimized for cell phones, as well as QR Codes and Data Matrix codes which can be read quickly and accurately with or without auto-focus. there are also scanners distinguished as housing type scanners which includes: handheld scanner, pen scanner, stationary scanner, fixed position scanner, PDA scanner, automatic reader and a cordless scanner.
Barcode scanners seriously have evolved as technology brought forth its valuable existence. Early scanners used the then-common RS232 serial interface which was an electrically simple connection means. then later barcodes began to use USB connectors and became a more convenient hardware option. Now, modern handheld barcode readers are operated in wireless networks according to IEEE 802.11g(WLAN) or IEEE 802.15.3(Bluetooth).
So suit yourself for you and your business today. there are many scanners to choose from. Analyze what’s best and make that selection process as enjoyable as possible.
