Barcode Scanners comes in different types and models. As you further your online sourcing for barcode scanners, you might realize that even for scanners with similar models and designs, their specs and properties can have a pretty varied range. Learning to identify the different types of scanners and what they can be used for can greatly help you in finding the perfect scanner for your company or yourself.
Wired Barcode Scanners
Wired scanners have a USB wire attached to at the bottom of the scanner to connect to a computer or a display device. The wired barcode scanner will then decode and transmit the data via USB to the display device.
Wireless Barcode Scanners
Wireless scanners are barcode scanners that come with a wireless receiver AKA dongle. This dongle allows the user to connect the scanner to the display device via RF signal transmission just like a wireless mouse. By setting the signal of the receiver the same as the transmitting device (ie: the scanner), the barcode scanner can decode and transmit the barcode information to the display device wirelessly.
Bluetooth Barcode Scanners
Bluetooth Barcode Scanners can be connected without a receiver to Bluetooth-enabled devices. Devices such as your computer, laptops, Apple and Android phones with Bluetooth turned on can be easily paired with the Bluetooth scanner to receive decoded barcode info from the scanner. For older devices without Bluetooth capabilities, the scanner can be connected by using a Bluetooth dongle (normally comes with a good quality scanner).
1-D Barcode Scanners
1-D Barcode Scanners scans all types of barcodes. Simply do a search for barcodes and go to the image section to look at how barcodes look like. Basically, 1-D Scanners can read and decode all types of barcodes in binary coding. In Layman words, the codes that are made of parallel lines of black and whites are barcodes. Better barcode scanners can decode data matrix codes as well.
2-D Barcode Scanners
2-D Barcode Scanners scans both Barcodes and QR Codes. Simply do a search for QR Codes and go to the image section to look at how a QR Code looks like. Basically, 2-D scanners is everything a 1-D scanner can do plus its ability to read all squared image QR codes.
Laser Scanners
Laser Scanners scanners with thin laser constructed beam. The benefits of laser scanners are its ability to scan codes from quite a distance away. Laser scanners are much more accurate and sensitive. They are also much accurate to detect codes that are compressed horizontally. Unlike their CCD counterparts, laser scanners are not able to scan electronic screens.
CCD Scanners
CCD Scanners are also known as image scanners. They are normally made from infra-red LED lights and decodes barcodes by analyzing the light reflected back at them. One major advantage CCD scanners have over their laser counterparts is that CCD scanners are able to scan electronic screens. CCD scanners have limitations over their scanning range due to their need to only read reflected light.
This list is not exhaustive, there are just so many different types of scanners out there available in the market and each has its own advantage and disadvantage. Just like in our case here, I've just listed to you not 7 barcode scanner types but I've actually listed a combination of 3 * 2 * 2 = 12 types of barcode scanners.
