The barcode and its history
This year marks the 50th anniversary of the barcode, one of the most important technologies in the world of logistics and retail.
A real innovation in the world of commerce, and initially conceived by Norman Joseph Woodland and Bernard Silver in the 1940s, this little tool has enabled companies to better manage sales, stocks and financial transactions in an efficient and automated way.
The barcode is now used in almost every aspect of our daily lives, from labelling products in shops to managing stocks in warehouses. Although now in its fifties, the barcode is being replaced by QR codes, which offer a number of advantages over the traditional barcode.
The different types of barcode
Today, there are several types of barcode with different functionalities.
Here they are:
The EAN code (European Article Numbering)
Developed in Europe and used worldwide, mainly in the commercial sector.
The UPC code (Universal Product Code)
Developed in the United States, and mainly used in North America, mainly in the commercial sector.
The QR (Quick Response) code
Allows you to store more information. Popularised with the rise of smartphones on the market.
The DataMatrix code
Allows more information to be stored. Often used in industrial applications, particularly for marking parts and products.
QR codesand Data Matrix codes are types of 2D barcode that can store more information than linear barcodes such as EAN and UPC. For example, they can store information such as URLs, e-mail addresses, telephone numbers, text, images and even files.
The QR code has become increasingly popular thanks to its ease of use with smartphones and the many applications it offers.
Barcodes and QR codes in Odoo
Barcodes and QR codes can be used in various Odoo applications. Here are a few examples:
- In the POS (Point Of Sales) area, we'll talk more about this below,
- In events to send tickets to participants and scan tickets at the event entrance
- In the "Presence" application, so that employees can have a badge with a barcode to check-in and check-out when they arrive or leave.
The use of barcodes and QR codes in the POS
POS (Point Of Sales) is an excellent example of the current use of barcodes and QR codes at the point of sale. With this functionality, employees can quickly and easily add products to a transaction, avoiding manual input errors. In addition, barcodes can be used to track stock levels in real time, enabling businesses to order new products before they run out.
The QR code can also be added to the till receipt so that customers can scan it and download their invoice via it.
In short, its aim is to simplify the exchange between a business and a customer.
POS systems often use barcode scanners to record customer purchases and maintain an accurate inventory. By using barcodes or QR codes, Odoo POS also saves time when making purchases. Customers can simply present their barcode or QR code for products to be scanned and added to their basket, streamlining the purchasing process and avoiding queues.
Odoo POS is one of the most advanced on the market. It offers a complete point-of-sale solution for businesses of all sizes.
Although QR codes are a fast-growing technology, it is unlikely that bar codes will be completely replaced any time soon. Both technologies have their specific advantages and uses, and it is likely that they will continue to co-exist for many years to come.
At the end of the day, the most important thing is to choose the technology best suited to your specific needs, whether it's barcodes or QR codes!
