A Laser Barcode Scanner uses a rapidly-moving laser to shine a particular frequency of light at the black and white bars of a barcode. The laser light is reflected off the barcode and read by a photo diode in the barcode scanner. The barcode scanner then interprets the reflection data and decodes it into useful data. To use a Laser Barcode Scanner, simply hold it near the barcode (read distances vary by model) and click the button or trigger. A Laser Barcode Scanner is suitable for almost any use, reads barcodes quickly and is very affordable. The Symbol LS 2208 is an excellent Laser Barcode Scanner for any application.

A CCD Barcode Scanner works much like a Laser Barcode Scanner, but instead of shining a laser at the barcode, the CCD Barcode Scanner measures light reflected from a series of light-emitting diodes (LEDs). This technology is older and not as fast as a Laser Barcode Scanner, but usually costs less. Some CCD Barcode Scanner models can read 2D barcodes. To use a CCD Barcode Scanner, hold it near the barcode (read distances vary by model) and click the button or trigger. Choose the Opticon LGP 6125 for CCD scanning.

An Imaging Barcode Scanner works much like a camera, taking a picture of the barcode and then using software to collect the barcode data from the image. An Imaging Barcode Scanner is ideal for two-dimensional (2D) and PDF417 barcodes and generally read quickly. The Intermec ScanImage 1470 Imager is suited for a wide spectrum of industries.

An Omni-Directional Barcode Scanner (also known as a Projection Barcode Scanner) works just like a Laser Barcode Scanner with the addition of several mirrors and other reflective devices to transform one laser line into many, all at different angles. This allows fast reading of barcodes at any angle, making an Omni-Directional Barcode Scanner perfect for point of sale installations, such as at a grocery store. The Symbol LS 9208 delivers both a high-performance processor and an innovative 100-line omnidirectional scan pattern for increased productivity at checkout.

A 2D Barcode Scanner can interpret two-dimensional barcodes, which store data in two dimensions, rather than in just a series of black and white bars. 2D barcodes look like checkerboards or a series of traditional barcodes stacked atop one another. 2D Barcode Scanners use both CCD and Imaging technology to read barcodes. The PSC PowerScan has been specifically designed to meet the demands of industrial users.

A PDF417 Barcode Scanner is just like a 2D Barcode Scanner, but also includes the ability to read PDF417 barcodes, which are a specific type of 2D barcode. PDF417 Barcode Scanners use both CCD and Imaging technology to read barcodes. The Metrologic MS9544 Voyager PDF is capable of decoding two-dimensional bar codes including PDF417, PDF417 truncated, and RSS composite.

A RS232 Serial Barcode Scanner connects to the computer's serial port and sends its information to the screen or to any program. A Serial Barcode Scanner is more complex than a Keyboard Wedge Barcode Scanner, but much more versatile: barcode data can be edited, re-ordered or otherwise changed before it is displayed, allowing customization of applications collecting and using barcode data. The PSC QS6000 Plus serial scanner has a high first pass read rate and the best speed-to-read of any scanner in its class.

A Wireless Barcode Scanner (also known as an RF Barcode Scanner or a Cordless Barcode Scanner) operate on wireless frequencies like a cordless phone. A Wireless Barcode Scanner transmits scanned data to a base station which is connected to the computer. The base station also doubles as a battery charger for the scanner. Wireless Barcode Scanner models vary by transmission range and by battery life, and are ideal for warehouses and retail stores. The Intermec Sabre 1552 has a cordless design to eliminates cables for safer and more reliable scanning.

A Batch Barcode Scanner work much like a Wireless Barcode Scanner: A base station is connected to a computer, while the scanner can move freely without wires. The difference is in transmission: A Batch Barcode Scanner scans barcodes and stores the data until it is returned to its cradle. A Batch Barcode Scanner is excellent for store inventory processes. The Symbol P360 batch scanner allows collection of up to 53,000 bar codes while lasting up to 12 hours on a single charge.

A Bluetooth Barcode Scanner is very similar to a Wireless Barcode Scanner but uses Bluetooth technology to transmit its data. The Bluetooth interface has a shorter range than other wireless technologies but is found in many small devices such as cell phones and PDAs. This makes the Bluetooth Barcode Scanner flexible since it can interact with a much wider array of devices. The Metrologic MS9535 Voyager BT communicates with its own base station or with other Bluetooth-equipped devices such as PCs, laptops and barcode printers.

A Handheld Barcode Scanner has a formed handle that allows comfortable use for long periods of time. Retail, Warehouse and other applications benefit the most from user comfort since employees must use the scanner daily. This is the most typical type of Barcode Scanner and can be found in many different styles and shapes. The Microscan MS-Q Quadrus combines the power of Microscan's popular smart camera Quadrus EZ into a portable handheld device.

A Pen Barcode Scanner (also known as a Wand Barcode Scanner) is the simplest type of barcode scanner. The tip of the Pen Barcode Scanner contains a light source and a photo diode. The pen is dragged across the barcode evenly and steadily and interprets the data. Since the tip must be in contact with the barcode and the motion steady, scans are not as quick as with a Laser or CCD Barcode Scanner. At the same time, the lack of moving parts means this type of scanner can withstand harsh conditions and can be made very small, making it good for portable devices. The PSC Wand features a sealed, self-cleaning ruby tip for long life and low drag, plus special optics for reliable barcode reading.

A Wearable Barcode Scanner fits on the hand or finger to provide ergonomic benefits to the user. Wearable Barcode Scanner models are usually wireless and can be found at sporting events and theatrical performances for scanning tickets, plus anywhere the user benefits from having two hands free without having to pick up the scanner to use it. The Symbol WSS 1040 leaves the user's hands totally free for handling packages, products, inventory or materials.

A Fixed Mount Barcode Scanner is installed at a predetermined position and used by dragging items over or past it. Grocery and Retail checkout lanes use fixed mount scanners to speed scanning of customer purchases: only the item must be moved, allowing users to move heavy objects without having to handle the scanner as well. A Fixed Mount Barcode Scanner is ideal for assembly lines or in shipping facilities - when items move past on a conveyor they are scanned automatically, without requiring a manual presence. The Microscan MS-710 is ideal for fast-moving barcode label scanning.
