Barcode
A visual representation of data that scanners can read, commonly used for tracking products in an inventory management system.
What is a barcode?
A barcode is a visual representation of data in the form of parallel lines (1D) or a pattern of squares (2D) that can be read by scanners. By assigning a unique code to each product, location, or order, businesses can fully digitize their processes. Scanning a barcode takes only a fraction of a second and virtually eliminates all input errors that occur with manual registration. The most common 1D standards are EAN-13 for consumer products and Code 128 for logistics applications, while DataMatrix and QR codes are increasingly used where more data per label is needed.
How does a barcode work?
A barcode scanner emits a beam of light or laser that is reflected by the black and white bars of the barcode. The scanner translates this pattern into a series of numbers or characters that uniquely identify a product or location. For 2D codes such as QR codes, a camera is used to analyze the two-dimensional pattern. The scanned data is then sent via a network to the connected software system, such as a WMS that automatically processes the inventory change. Within Wabber's WMS, each scan is directly linked to the corresponding order or location, making the entire goods journey from inbound to outbound fully traceable.
Example
In a warehouse using Wabber's WMS, each shelf location receives a unique barcode. When an employee stores goods, they first scan the location barcode and then the product barcode with an industrial scanner. The WMS automatically registers which product is stored at which location. When picking an order, the scanner displays the correct location and verifies upon scanning whether the right product has been picked. This reduces picking errors to a minimum. This process also generates valuable data for KPI dashboards, giving managers real-time insight into pick speed, error rates, and warehouse occupancy.
Why are barcodes important?
Barcodes form the foundation of efficient inventory management and logistics processes. They save an enormous amount of time compared to manual entry and ensure reliable registration of product movements. In addition to traditional 1D barcodes, 2D codes are increasingly used for track-and-trace, product authentication, and digital registration processes at events. Wabber integrates barcode technology into all its tracking systems for industry, logistics, and events. Combined with Wabber's MDM platform, barcode scanners are centrally managed, ensuring configuration and firmware updates are automatically rolled out to all devices.

Frequently asked questions
What is the difference between a barcode and a QR code?
A traditional barcode (1D) consists of vertical bars and typically contains a numeric sequence of 8 to 13 digits. A QR code (2D) consists of a square pattern of black and white blocks and can contain much more information, including text, URLs, and structured data. QR codes can also be scanned with a regular smartphone.
Which barcode scanners work with Wabber's WMS?
Wabber's WMS is compatible with a wide range of industrial barcode scanners, including handheld scanners and fixed scan units. Through our Hardware & MDM program, we manage scanners centrally, including configuration and updates. We advise on the right scanner based on the work environment and barcode type.
Can I use barcodes for track-and-trace of shipments?
Yes, barcodes are a commonly used method for track-and-trace. At every step in the logistics process, from storage to delivery, the barcode is scanned. This allows the complete route of a shipment to be tracked in real-time in the TMS. This provides transparency for both your own organization and your customers.
How much data can a barcode contain?
A standard 1D barcode such as EAN-13 contains 13 digits, which is sufficient for product identification. Code 128 can hold up to 80 alphanumeric characters. A 2D code like a QR code can store up to 4,296 alphanumeric characters, including URLs and structured data. The choice of the right barcode type depends on the amount of information you want to capture and the scanning environment. Wabber advises per situation which format is most suitable for your tracking system.
