Barcode Scanners – Types, Features and Benefits

Posted on by

A barcode scanner is a device that is used to read the printed barcodes. A barcode consists of a series of parallel, adjacent bars and spaces that are decoded with the intensity of the light reflected by them. When the scanning is initialized, the scanner lens reads the entire code with the help of the light source and converts the code into 0s and 1s. The space reflects the light where as the dark bar absorbs the light. This is called digitalizing. Thus decoding is done for the barcode and the result is sent to the output device.

Types of barcode scanners:

The barcode scanners can be classified into two main categories. They are

â?¢ Contact readers: These devices are normally held in the hands. To read a barcode this type of readers must either touch the code or come close to it.

â?¢ Non-contact readers: These devices need not be close to the barcode to read the code. These scanners use either a moving beam or a stationary beam, but mostly they have a moving laser light beam. These scanners come in both handheld and fixed mount configurations.

Features of barcode readers:

The barcode scanners consist of an internal decoder and a cable, which are connected to the computer through compatible ports. It consists of a light source, a lens and a photo conductor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuit. It analyzes the barcode’s image data provided by the photo conductor and sends the barcode’s content to the scanner’s output port. Advanced readers use laser-scanning technology. Barcode readers are available in several forms like in hand-held, hands-free, wearable, scan engines, laser or digital.

Benefits o f barcode readers:

The benefits of the barcode readers can be classified based upon their types.

â?¢ Benefits of Contact barcode readers:

â?¢ Benefits of non-contact readers:

o Non-contact readers works from a distance of several inches to several feet depending upon the scanner design and the size of the input. So, non-contact scanners can be used in almost any barcode reading application.

o These scanners are mostly put into use when the input cannot be brought near the scanner like heavy machinery or objects.

o The fixed position non-contact readers are best suited for applications where the items move past the scanner.

o These scanners are best suited for the mobility applications.

These scanners can perform high-end and heavy-duty work for long durations.

â?¢ Overall benefits of barcode scanners:

o Use of barcodes provides a fast, easy and accurate mechanism to enter data into a computer system for data collection or data lookup.

o Accelerates workflow efficiency and speed ups throughput process

o Eliminate data entry errors

Asus EEE PC T91 Features Full Touchscreen and Weights For Only Two Pounds

Posted on by

The Asus EEE PC T91 is the first tablet netbook by ASUS with full touchscreen feature and is already available in the US market now. Broadly, touchscreen tablets are an off-repeated combination of excitement and disappointment in many ways. Mostly what’s out there are great ideas with mediocre hardware, mix it with sleek and modern shape, but very bad execution of the touchscreen feature. Let’s see if the T91 would be able to sidestep these issues.

The T91 is a compact little machine and has a pretty attractive physical appearance. It weights only two pounds including the lithium polymer battery with a thickness of only an inch. The LCD can swivel to the left and move quite smoothly, giving a sturdy feeling about the netbook. The 8.9-inch EEC PC T91 provides a small and standard keyboard that allows surprisingly easy and efficient typing. The machine is certainly compact but not cramped and features a nice clickness. The backlit LED resistive touch panel of this machine is considerably bright and good looking, though, at the same time, its very glossy and takes fingerprint easily. It boasts two USB, one VGA, and two audio ports, and a power button on the screen’s left bottom edge. There is another button directly to the right of the power button, which is one of the means of activating the touch interface. Moreover, it has a flexible stylus fitted under the bottom right side of the main body.

When it comes about the specs of T91, it has an Intel Atom Z520 1.33 GHz CPU, 1GB of RAM, 16GB SSD, Intel GMA500 graphics and a lithium polymer battery that offers 5 hours of constant backup. Other than that, it also features 802.11 B/G/N Wi-Fi, Bluetooth 2.1 plus EDR and 10/100Mbps Ethernet.

To get the touchscreen appropriately responsive, the Asus EEE PC T91 comprises an easy, 9-point calibration procedure and also loaded with some custom-built software called Touch Gate interface. The touchscreen interface can be activated from the usual XP desktop in three different ways- via the desktop icon, the slider icon on the top of the desktop and a physical button located right to the power toggle. Hitting any of those will bring up the main Asus Touch Gate interface which is basically a very simple row or different icons that can be reorganized in any order. Memos and Notepad is pretty self explanatory without plenty of whistles and bells, but the applications work very much efficiently. The touchscreen is quite responsive and calibrated to both fingertip and stylus, so the notes can be made with actual handwriting after getting a little used to with the process.

Clicking your finger left to the Touch Gate interface, it will appear a screen called ‘Widget Screen” which comes with many pre-installed and customizeable widgets from Yahoo. Overall, the software with the EEE PC T91 is designed really nicely and operates pretty good as advertised. Still, there are few limitations with the CPU and the responsive touchscreen, we had to move slower than we usually want to.

Most used batteries for mobile phones are lithium polymer, lithium ion, and nickel metal hydrite. First two categories are slimmer with larger power capacity and do not discharge when the phone is switched off. Such batteries can be recharged without consequential reduction in capacity. Nickel batteries are heavier with less power capacity, discharges when not in use, and capacity reduces by frequent recharging. However sets with former lithium batteries cost higher.
Mobile Phone Size
Ordinarily one would find two sizes of mobile phones in the market; palm size and medium size. Palm size ones are easier carrying and can be conveniently kept in the pocket or purse.
