The difference between bar codes and QR codes

Barcodes, which are often used in checkout, inventory and delivery management, are processed by reading the numbers from 0 to 9 with a special device from randomly arranged bars of different thicknesses.
However, barcodes can only contain less than 20 characters of information, and can only convey the minimum necessary information such as product name, amount and quantity.
In comparison, QR codes can read up to 7,089 characters (in the case of numbers only), and the amount of information that can be read greatly exceeds that of bar codes. Also, the code itself can be designed in full color for good visibility, making it suitable for placement on printed materials.
The Future of QR Codes
QR codes can cover a very wide range of content, and are used to guide people to campaign sites, inventory management in warehouses, medical care, city infrastructure such as lockers using QR keys, and everything in between. In recent years, they have also been used for electronic payments using QR codes and smart phones.

The advantage of using QR codes for electronic payments is that, unlike electronic money, users are not limited by the type of smartphone they use. All you need is a camera to use it.
In addition, since electronic payment using QR codes requires only a smartphone or tablet and does not require a dedicated device, the initial cost of introduction can be reduced.
In recent years, smart phone payments using QR codes have been spreading due to the ease of use described above, but some problems have surfaced along with their spread.
In China, where the introduction of QR payments has been active, there have been many cases of fraudulent transactions in which the QR code used for payment is tampered with to defraud people of their sales. If these problems continue, it may hinder the spread of QR payments in the future.
