The Size of a MaxiCode Barcode

The Size of a MaxiCode Barcode

  • MaxiCode is a two-dimensional (2D) matrix barcode that has a fixed size of 1.1 inches (2.79 cm) in diameter. The size of the barcode is standardized and cannot be changed. The fixed size is designed to ensure that the barcode can be scanned easily and accurately by barcode scanners, even if it is printed at a small size or if the scanning angle is not optimal.

  • The MaxiCode barcode consists of a hexagonal pattern of dots arranged in a grid of 33 rows and 30 columns. The center of the barcode contains a bullseye pattern that serves as a reference point for the scanner. The data is encoded within the hexagonal pattern of dots using a Reed-Solomon error correction algorithm, which allows the barcode to be scanned accurately even if some of the dots are missing or damaged.

  • The fixed size of the MaxiCode barcode means that it can be printed at a high density without compromising the readability of the barcode. This is important for applications where space is limited, such as shipping labels or packaging, where the barcode needs to be small enough to fit onto the label or package, but still readable by a scanner.

Overall, the fixed size of the MaxiCode barcode makes it easy to use and reliable, as it ensures that the barcode can be read accurately by any barcode scanner that supports the MaxiCode symbology.

Reading of MaxiCode Barcode by any Barcode Scanner

MaxiCode is a proprietary barcode symbology that was developed by United Parcel Service (UPS) in the 1990s for use in their logistics and shipping operations. As a result, MaxiCode barcodes are primarily used in the logistics and transportation industries, and are most commonly seen on UPS packages and labels.

  • There are several types of barcode scanners that can read MaxiCode barcodes, including handheld scanners, fixed mount scanners, and mobile computers. Handheld scanners are the most common type of scanner used in logistics and transportation applications, as they are portable and easy to use. Fixed mount scanners are typically used in automated sorting and tracking systems, where packages are scanned as they pass through a conveyor system. Mobile computers are handheld devices that combine barcode scanning with other functions such as inventory management or data entry.

  • Barcode scanners that can read MaxiCode barcodes are typically designed for use in logistics and transportation applications, and may have specialized features such as long-range scanning or ruggedized construction to withstand the harsh conditions of shipping and handling environments.

  • To ensure that a barcode scanner can read MaxiCode barcodes, it is important to check that the scanner supports the MaxiCode symbology and has been configured to read MaxiCode barcodes. Some barcode scanners may require firmware updates or configuration changes to enable MaxiCode scanning.

However :- MaxiCode barcodes can be read by any barcode scanner that supports the MaxiCode symbology. MaxiCode is a two-dimensional (2D) matrix barcode that encodes information using a hexagonal pattern of dots. The data is encoded using a Reed-Solomon error correction algorithm, which allows the barcode to be scanned accurately even if some of the dots are missing or damaged.

Overall :- While MaxiCode is a proprietary barcode symbology that is primarily used in the logistics and transportation industries, it can be read by any barcode scanner that supports the MaxiCode symbology. Barcode scanners that can read MaxiCode barcodes are widely available and can be used in a variety of applications, from shipping and logistics to inventory management and asset tracking.
