Laser Bar Code Reader are used to develop object recognition systems for a wide variety of industrial applications. Examples include barcode reading, automated storage, or drug delivery to ensure patient safety. Barcode scanners work by passing a beam of light across the barcode and measuring the amount of light that is reflected. The black bars in the barcode reflect less light than the white space between them. The scanner then converts the light energy into electrical energy, and the decoder converts the electrical energy into data that is sent to the computer.
Different Types of Bar Code Readers
Here is the hardware configuration of the eight main types of barcode scanners:
A portable scanner is the most common type of scanner. It is simple in design and easy to use. Some people call them scanner guns because the user must point a laser Bar Code Reader at the gun and pull the trigger. Handheld scanners come in two types: wired and wireless. You can get a wireless scanner for convenient portable scanning. We will discuss that later. Most handheld scanners also provide manual operation by placing the scanner on a stand.
The presentation scanner’s design allows you to place it on your desk without having to hold it in your hand. They are portable scanners that do not require scanning a bar code to operate. A handheld scanner for reading with a smaller scanning area than a presentation scanner is called a monocular scanner. However, there is a wider area for scanning with hands-free display scanners. These scanners are common in retail settings. Its larger area makes imaging less cumbersome and enables faster scanning. When you set the reader to automatic scanning mode, you can scan hundreds of laser barcode readers per second.
Computer scanners love presentation readers. It also works silently, just show the barcode from the Bar Code Reader. However, counter scanners are often installed rather than sitting on desks. In-room scanners are common in stores where customers pay in person. Customers only need to provide the printer display code and it is very easy to use. You can add counter scanning mode to your POS system.
Stationary readers differ from other types of Bar Code Reader. They are specifically designed to integrate into large-scale automation systems. If you are looking for a barcode scanner that can be mounted on a kiosk or conveyor belt, you should purchase a terminal scanner. You don’t have any buttons or triggers to press to get rid of it. Stationary scanners can read bar codes at high speed without human intervention. They are usually in standby mode for automatic scanning. However, some models require the use of an external sensor or controller to operate the scanner.
A Wearable Reader
Wearable Bar Code Reader are also known as wrist scanners. To use it, you need to wear the scanner on your arm, finger, or hand. Some wearable scanners are connected to a small box that can be worn on the back of the hand. Other rings are similar to rings worn on fingers. A wearable scanner keeps the scanner close to you at all times. Unlike handheld scanners, wearable scanners give you the freedom to use your hands while holding the scanner to scan manually. Some wearable scanners have an automatic scanning mode or a continuous scanning mode that does not require an operator. But some people want you to activate the scan by pressing the activation button. Some allow you to activate the scanner using voice recognition.
Laptop scanners are more versatile than basic scanners. They offer complete freedom as both scanner and computer are in one mobile device. Unlike other types of scanners, which require a connection to transfer scanned barcodes to a computer database, the database resides on the scanner’s laptop. Therefore, it is suitable for barcode applications that require real-time movements, such as asset tracking and inventory management. When using a mobile reader, you can move freely in shops or stores. They have a large internal memory to store information. They can also communicate with other computers or inventory systems via mobile networks (WAN) and Wi-Fi networks.
Barrier cleaners are usually fixed. To scan them with a laser Bar Code Reader, you need to remove the coded item or pass it through the scanner’s hole. We often use slot scanners to read barcodes on security cards. They are often used as access keys or ID cards.
The pen cylinder is the cheapest type of scanner on the market. It is also very durable as it has no moving parts. But it may take a while to learn how to use it. You must attach it directly to the barcode. And to select the barcode information, you have to hold it at an angle. Most pen owners need a certain speed to move the pen around the barcode.
