Barcodes are the familiar parallel black lines used on product and service labels and tags that give it a distinctive identification. They were invented half a century ago and are now ubiquitous, appearing on supermarket goods, cars and mail parcels, books and inventory objects, and so on. Their use is promoted in order to increase productivity and save money and time.
Barcodes have been upgraded from linear to two-dimensional barcodes as a result of technological advancements and the use of integrated circuits. More advancements and advances can be seen in the future, with barcodes charting new territory as their use expands to include more industries. However, as with all technological discoveries and innovations, the old gives way to the modern, and barcodes which become outdated as a result of new technologies. Radio Frequency Identification, or RFID, for example, can one day render barcodes obsolete. However, owing to the disparity between the costs involved in both, this could never happen. They can continue to coexist, with barcodes reserved for simplified operations and RFID reserved for more technical applications.
The current scheme will be used in the future, with linear barcodes for basic applications and two-dimensional barcodes for more advanced applications. At first glance, the future seems to be as follows:
• Expanding the use of barcode technologies to include previously untapped fields, as well as extending barcodes into more comprehensive roles in areas such as supply chain management.
• The use of two-dimensional barcodes, which provide more fields to store information around the length and width of the barcode, will allow for more information collection. • Barcode technologies will expand, allowing the use of barcodes simpler with the inclusion of more fields.
• Barcodes would have more symbologies than ever, allowing them to be more customised.
The current acceptability of barcodes can be used to predict their potential. There is no evidence that the use of linear barcodes is diminishing, indicating that they will continue to be used in situations where only small volumes of data must be processed. Where linear barcodes are deemed insufficient, 2D barcodes are gaining acceptance. With the creation of newer symbologies for 2D barcodes, the possibilities for these barcodes are endless.
Colored three-dimensional barcodes are a recent addition to the barcode market.
They are also known as coloured barcodes or 3D barcodes, and they have the ability to store a tremendous amount of data. Their current implementation is constrained due to their inexperience and lack of simple symbologies and tools. The HCCB, or high ability colour barcode, from Microsoft is the most often used symbology for these coloured barcodes. Colorized CL barcodes, which can store 73 KB of data in a small square barcode, are another symbology. The latest PM code is a symbology that is among the strongest. PM stands for Paper Memory, and it has a size size of 0.6 to 1.8 megabytes. With 256 colours and a memory range of up to 1236 GB, barcode storage with the IP-based PM code is the pinnacle.
The QR code, or Fast Response code, is also being hailed as the potential barcode. The QR code is a square-shaped matrix that can hold more data than linear barcodes. They are widely used in countries such as Japan, where most mobile phones have cameras that can decode this code. They’re great for monitoring apps and saving addresses, and users can also make their own QR codes for them.
As a result, amid the development of more modern RFID and other methods of recognition, the barcode will continue to be used. They are widely accepted for a variety of applications due to their cost effectiveness, time savings, and ease of use, and they will continue to be so.
