Types of Barcode Scanners: Choose the Best Option for You

 Barcode scanners, also known as POS scanners, are stationary or hand-held devices used to scan and read information from a barcode. It comprises of three essential parts- scanner, decoder, and cable, and consists of a light source, a lens and a light sensor that translates optical impulses into electrical ones. 

There are 5 distinct types of barcode scanners- 

1.    Laser Scanners: As the name suggests, laser scanners function by using laser as light to reflect through a series of prisms to read a barcode. These are designed specifically to read linear 1D barcodes and can read from 6 inches to 2-feet away. 

2.    Image Scanners: These function by using tiny digital camera to scan the image of a barcode which is then read by the connected computer system for inventory purposes. 

3.    2D Area Imagers: A 2D image scanner can efficiently scan all kinds of barcodes including 1D, 2D and stacked. The prime advantage of a 2D image scanner is that it can scan in any position. 

4.    CCD Barcode Scanners: Charge couple devices (CCD) barcode scanners come with a series of miniature sensors placed at the front of the reader. The scanner generates waveforms corresponding to bars and spaces, and the information is decoded within the scanner and transmitted to the computer system. 

5.    Pen Readers and Barcode Wands: In this type of scanner, the tip comes with a light source and photodiode.  

Once you have determined the type of scanner you would need for your business, you need to choose the forms of the scanner. 

6 Forms of Barcode Scanners 

1.    Handheld Barcode Scanners: These types of scanners are most widely used, and they come in both corded and cordless variations. Handheld barcode scanners are easy to use. All you need to do is hold the scanner, point it to the barcode and press the button. Some handheld barcode scanners come with stands and can be conveniently used in industries such as warehouses, grocery stores, healthcare facilities, and others.

2.    In-Counter Barcode Scanners: These are stationery devices that allow staff and customers to swipe barcodes across the reader for quick and easy scanning. You can spot an in-counter barcode scanner on top of checkout counters at grocery shops. 

3.    Fixed Mount Barcode Scanners: This form of barcode scanners is designed for more specialised uses in industries such as warehousing, manufacturing, and logistics. Designed for integration into a large automation system, sixed mount barcode scanners are available in a wide range of speeds and can read codes without any manual handling. 

4.    Corded and Cordless Barcode Scanners: The traditional barcode scanners require to be connected using a cord. However, with the advancement in Bluetooth technology, cordless barcode scanners became more popular. When data is transferred via any wireless mode, the information is transmitted from a remote reader to the base station that in turn connects to a computer. Some cordless barcode scanners come with batch memory.

5.    Omnidirectional Barcode Scanners: Also known as presentation scanners, omnidirectional barcode scanners are designed for stationery, wide area reading. There is no aiming involved unlike handheld barcode scanners. All you need to do is place the barcode before the scanner and the code is automatically scanned. 

6.    Mobile Units: Also called handheld computer devices, mobile units are designed for more than barcode scanning. These do not need cords or heavy stationery devices to function. All you need is a stable internet connection. Mobile units are essential for inventory management in large department warehouses that have volumes of heavy items. 

Note: While buying a barcode scanner, ensure that you check the scanner strength and pick a physically resilient device.
