Barcode scanners or barcode scanners are electronic devices for reading bar codes developed. Like a flatbed scanner, it has a lens, light sensor and a light source, optical translated into electrical impulses ones. Almost all have a barcode scanner decoder circuitry, which analyzes the image data of the barcode and sends it to the output of the scanner. It is the sensor, which makes this process possible.
Wireless Barcode Scanners
WirelessBar code scanners are designed to enable the user of bar codes, even if he or she continues to walk away from your PC. In other words, it is very convenient mobile. In other cases, you can free themselves from the PC and still be able to read and write the information in a database on the network. This means that the barcode scanner has a network connection, which navigates the software in the data source to update data.
Evaluate before buying a wireless barcode scanner, toTo analyze your situation at work and if you only need a cable longer or that you really need a portable data collector with a mobile handheld computers, and integrated barcode scanner equipped. If you only need a longer cable, you can for the wireless wedge scanner. You can save more with this type because they are less expensive in comparison to the technologically advanced brethren.
Wireless wedge scanner
Wireless wedge scanners are actually similarcorded scanners. They have two components, the base station and the scanner. It is the scanner, which transmits to the base station, according to the base station, the "decoded" bar code data into the computer network.
The combination of the base stations to the wired computer is also similar to the combination of process scanner. You use the RS232, USB or PS2 port. When using the ad-PS2 USB connections are the data to the PC keyboard buffer. Itappear as ASCII text on the screen of the PC anywhere the cursor is blinking. If you are using the RS232 interface, the scanned input, but it is not displayed at the blinking cursor. The data is only transferred and go place, where it is programmed to.
Wireless wedge scanners have 2 types. They differ only on the type of scanner in conversation with the base station. Often they use a so-called "frequency algorithm" that makes use of the 14 available channels hoppingwith a 2.4-GHz frequencies developed for wireless communication.
There are also cases where they use the Bluetooth protocol. Although they have similar performance and range of the Bluetooth protocol lets your scanner on any Bluetooth-enabled receiver, send the ASCII text there. With this method it is very easy to list any Bluetooth-enabled device, and only by-pass your base.
When buying a wireless wedge scanner with BluetoothProtocol, make sure its scanner has a driver that enables communication between the host device. In fact, there are scanners that even work with PocketPC devices.
Here are the top wireless bar code scanner on the market:
Metrologic MS9535 Voyager
The wireless bar code scanner offers the convenience of mobility because of its Bluetooth v1.1 wireless technology. It is the Voyager series' youngest member, the continuation of the saga of the combination of high performance, patentedTechnology and futuristic design. It can be mounted on the wall or countertop.
Metrologic MS9535 Voyager is a cable-scanning device that has the data transmission CodeGate technology. It supports both client and master modes, and it can scan 12,000 per charge. It also has a 10-meter operating range, and can decode RSS Expanded, RSS Limited and RSS-14 bar codes.
Symbol LS4278
The wireless bar code scanner offers excellent barcode scanning capabilities,especially with its 2v1.2 Bluetooth wireless technology. Apart from being inexpensive and easy to operate, the users are moving because of the convenience of up to 50 meters while scanning items. They are also guaranteed a secure and reliable wireless data transmission due to the built-in Bluetooth WPAN, or wireless personal area networking protocol.
Datalogic Gryphon BT100 & BT200 Barcode Scanners
These two wireless bar code scanner as a new addition to the GryphonMobile Family. Both are designed with the latest innovations in Bluetooth technology. You have the Datalogic Bluetooth radio module with Bluetooth 1.1-compliance with technical standards and easily communicate with any device that has an external commercial Bluetooth dongle, Bluetooth module, such as laptops, PCs, PDAs, printers, cell phones and the like.
Datalogic Gryphon BT100 & BT200 Barcode scanners are capable of decoding 270 scans per second. They are also user-friendlyand intuitive. Moreover GryphonBT developed it with a "blue spot" feature, a good reading feedback, making the user the task very easy in the midst of noisy environments.
