, barcodes have some limitations where

QR Codes

do not. Firstly, due to the one-dimensional nature of the barcode, there is a limit to the amount of data it can store.

In addition, the way barcodes are used means that, in practice, they are usually not unique. Famously, barcodes are used to identify item type rather than individual items.

If you’re using a self-checkout machine, for example, and you have three packs of microwave rice to scan through, if each one is the same then you can scan one of the packet’s barcodes three times, rather than each individually.

As a result, if you are attempting to track more than one of the same asset using barcodes, you will need to make sure your barcodes have unique tags on them, rather than just using those they have already.

Key Considerations for Choosing the Right Mixer Supplier

The symbol versions of QR Code range from Version 1 to Version 40. Each version has a different module configuration or number of modules. (The module refers to the black and white dots that make up QR Code.) "Module configuration" refers to the number of modules contained in a symbol, commencing with Version 1 (21 × 21 modules) up to Version 40 (177 × 177 modules). Each higher version number comprises 4 additional modules per side. Each QR Code symbol version has the maximum data capacity according to the amount of data, character type and error correction level. In other words, as the amount of data increases, more modules are required to comprise QR Code, resulting in larger QR Code symbols.

How to determine the version of QR Code to be used

Suppose the data to be input consists of 100-digit numerals. This can be achieved by following the steps described below:

1. Choose "numeral" as the type of input data.
2. Choose a data correction level from the alternatives of L, M, Q and H. (M is assumed here.)
3. Find a figure in the table, 100 or over and the closest to 100 that is at the intersection with a correction level M row. The number of the version row that contains this figure is the most appropriate version number.

In this example, Version 3 QR Code (29 x 29 modules) is the most appropriate version.　　Related page: Error correction feature
