Most smartphones have built-in QR scanners, which are sometimes built in the camera. There are many new uses for the QR code, from transferring payments to determining objects' positions within augmented reality. Their new QR codes include traceability, brand protection, and anti-forgery measures. In 2020, Denso Wave continued to improve on their original design. The use of smartphones led to an increase in the number of companies using QR codes. Initial uptake of the idea was slow however, in 2002, the first mobile phones containing built-in QR readers were marketed in Japan. This meant anyone could make and use QR codes.

This led them to choose the iconic square shape that is still used today.ĭenso Wave made their QR code publicly available and declared they would not exercise their patent rights. They also wanted it to have a distinctive design to make it easy to identify. The development team behind the QR code wanted to make the code easy to scan so that operatives did not waste time getting it at the right angle.

And much more – a company in the UK called QR Memories even creates QR codes for use on gravestones, allowing people to scan the code to read more about that deceased person’s life (if they have an obituary or news story relating to them online).

Access Wi-Fi by storing encryption details such as SSID, password, and encryption type.

Authenticate online accounts and verify login details.

Link directly to download an app on the Apple App Store or Google Play.

The data stored in a QR code can include website URLs, phone numbers, or up to 4,000 characters of text. This allows it to house significantly more data. But a QR code is read in two directions – top to bottom and right to left. That means they can only store a small amount of information, usually in an alphanumeric format. Standard barcodes can only be read in one direction – top to bottom. To achieve this, they developed a type of barcode that could encode kanji, kana, and alphanumeric characters. They needed a more accurate way to track vehicles and parts during the manufacturing process. The first QR code system was invented in 1994 by the Japanese company Denso Wave, a Toyota subsidiary.

While they may look simple, QR codes are capable of storing lots of data.
