How Does an Overhead Barcode Scanner Work?

Barcodes have become an integral part of our lives, and they are found almost everywhere - from supermarkets to hospitals, libraries to airports. They have revolutionized the way we manage inventory and keep track of things. And an overhead barcode scanner is one of the most commonly used types of barcode scanners. But how does it work?

What is an overhead barcode scanner?

Before discussing how it works, let's define what an overhead barcode scanner is. An overhead barcode scanner is a machine mounted above a surface, typically a conveyor belt, that automatically captures barcode data from objects as they move underneath the scanner.

How does it work?

There are several parts to an overhead barcode scanner that work together to identify a barcode and translate that information into usable data. Here's how it works:

1. The scanner uses a light source.

Inside the scanner, there is a light source that emits either a red or green light. This light shines downward onto the objects moving through the scanner.

2. The scanner captures an image.

As the objects move beneath the scanner, an image is captured by a camera inside the scanner. This image is typically in black and white and shows the barcode, as well as any other markings on the object.

3. The scanner decodes the barcode.

Using software and algorithms, the scanner decodes the barcode and translates it into usable data. The data can then be sent to a computer system or other device to be processed.

4. The scanner reads different types of barcodes.

Overhead barcode scanners can read several types of barcodes, including one-dimensional (1D) and two-dimensional (2D) barcodes. 1D barcodes are the traditional barcode that has bars of varying widths and spaces between them, while 2D barcodes are more complex, often resembling a square with dots and shapes inside of it.

5. The scanner can handle high volume.

Overhead barcode scanners are often used in high-volume environments, such as manufacturing plants and distribution centers. They can handle hundreds or even thousands of scans per hour, making them an efficient way to keep track of inventory or product movement.

What are the benefits of using an overhead barcode scanner?

Overhead barcode scanners offer several benefits that make them a popular choice for businesses and organizations. Here are a few:

Accuracy: Overhead barcode scanners can read barcodes quickly and accurately, reducing the chances of errors.

Efficiency: With the ability to scan hundreds or thousands of objects per hour, overhead barcode scanners can significantly improve productivity.

Traceability: By tracking inventory and products as they move through a facility, businesses can improve traceability and maintain a better record of what they have in stock.

What should you consider when choosing an overhead barcode scanner supplier?

When considering an overhead barcode scanner supplier, there are a few important factors to keep in mind. Here are some things to consider:

Quality: Look for a supplier that offers high-quality scanners that are built to last.

Customer service: Choose a supplier that offers excellent customer service and support, so you can get help when you need it.

Cost: While cost is a consideration, don't make it the only factor. You want to choose a scanner that meets your needs and is reliable, even if it costs a bit more.

In conclusion, an overhead barcode scanner is an efficient and accurate way to manage inventory and track product movement. By using a light source and camera to capture barcode data and translate it into usable information, these scanners offer a range of benefits for businesses and organizations. When choosing a supplier, be sure to consider factors such as quality, customer service, and cost.
