Frequently asked questions

Everything you need to know about barcodes

A barcode is a visual representation of data in the form of bars, bars or squares. This consists of a series of numbers and/or letters that are converted into barcode format using a special coding technique. Barcodes are used to store and transmit information efficiently and without errors.

A QR code can store 4,296 alphanumeric characters or 7,089 numeric characters, while most 1D barcodes can only store up to 20 numeric characters. For example, a QR code can contain all basic customer information such as name, email, address and phone number. This is not possible with a 1D barcode.

Numerous barcode types exist, some of which are the best known:

  • EAN-13 and UPC-A: These barcodes are commonly used in retail to identify products.
  • Code 39 and Code 128: These barcodes are used in various industries and support both numeric and alphanumeric data.
  • QR Code and Data Matrix: These barcodes offer the ability to store larger amounts of data and are optimized for use in the digital world.

There are many more barcode types, each with specific purposes and requirements. All major barcode types are supported by our barcode generator.

Barcodes are read with the help of a barcode scanner. The scanner emits light onto the barcode and captures the reflected light pattern. Then the pattern is converted into digital data and decoded by the scanner software or hardware to extract the information in the barcode. The exact technology varies depending on the scanner type, such as laser scanner, charge-coupled device (CCD) scanner, or imager (camera).

After scanning the barcode, a digital preparation takes place. The processed information is stored as text. These are then transmitted to connected output devices such as software or POS systems. Wireless scanners can cache codes to allow scanning over a wider area.

Barcodes offer a variety of benefits in the business world, including:

  • Efficiency: Barcodes enable fast and accurate data capture, resulting in improved workflows and lower error rates.
  • Inventory management: Barcodes make it easier to monitor stock levels, track products and take inventory.
  • Automation: Barcodes can be used in automated processes to facilitate data exchange between different systems.
  • Time savings: By quickly capturing information, employees can work more efficiently and save time.
  • Sales optimization: Barcodes enable a smooth checkout process and accurate pricing, resulting in an improved customer experience.

To create a barcode, you need a barcode generator. You can enter the desired information, select the desired barcode type and adjust other settings. Then the software generates the barcode, which you can save or print.

There are a variety of software solutions for creating barcodes. Online barcode generators are widely used and offer an easy way to create barcodes directly in the web browser.

To print barcodes, you need a barcode printer or a conventional printer that supports barcode labels. Make sure you set the correct print settings for size, contrast, and resolution to ensure that the barcode is readable. Use barcode labels or special barcode paper for best results. You can create barcodes with our online barcode generator.

Barcodes play a crucial role in the retail industry. They are used to label products, record prices, perform inventories, automate the sales process and enable tracking of products in the supply chain. Barcodes enable efficient and accurate data exchange between vendors, suppliers and logistics providers.

Barcodes are an essential part of the supply chain. They enable unique identification of products, facilitate the traceability of goods through the entire delivery process, and enable efficient inventory management and warehousing. Barcodes play a critical role in tracking and monitoring products from manufacturing to transportation to the retail shelf.

In warehouse management, barcodes are used to efficiently identify and track goods. Barcodes are applied to packaging, pallets or storage containers to facilitate inventory, receiving, shipping, picking and putaway. By scanning the barcodes, warehouse staff can obtain accurate information about stock levels and track the location of goods.

The size of a barcode depends on the type of barcode used and the application. There are guidelines and standards for the minimum size of barcodes to ensure optimal readability. As a rule, a barcode should be large enough to be captured by a standard barcode scanner.

The validity of EAN codes is not limited in time. You can use EAN codes as long as you want to mark your products. However, a number should not be reused for 4 years after an item has ceased production to ensure transparency and uniqueness in commercial transactions. After these 4 years you can assign the number to another product. For certain product groups, this blocking period may also be shorter or longer.

A barcode consists of a linear arrangement of bars or bars, while a QR code is a matrix-like arrangement of square modules. A QR code can store 4,296 alphanumeric characters or 7,089 numeric characters, while most 1D barcodes can only store up to 20 numeric characters.

Yes, there are a variety of standards for barcodes developed by international organizations such as GS1 (Global Standards One) and ISO (International Organization for Standardization). The standards include various barcode types such as the EAN-13 (European Article Number), the Code 39, the Code 128, the Data Matrix and the QR code. In addition, the standards also include coding rules to ensure the correct capture of barcodes.

The barcode standards also provide guidelines and recommendations for the proper use of barcodes, including their size, print quality, contrast requirements, and placement on products or packaging. These guidelines help ensure that barcodes can be reliably captured and decoded by barcode scanners.

The technology of barcodes has evolved over time to meet the growing demands and advancement of technology. Early barcodes consisted of simple barcodes, while later 2D barcodes such as QR codes were developed that could store more data. Reading technology has also improved, from simple laser scanners to powerful image processing devices. Nowadays, barcodes are also increasingly scanned using mobile devices and apps, which opens up new application areas and possibilities.
