Background<\/h2>\n<\/div><\/div>

The QR code (Quick Response Code) is a two-dimensional (2D) barcode, unlike the traditional one-dimensional (1D) barcode. <\/p>\n

It was created in 1994 by Masahiro Hara, a Japanese engineer, in order to track the progress of spare parts during manufacture in Toyota's factories. <\/p>\n

Released under a free license five years later for use by anyone, the QR code became popular with the arrival of smartphones in the late 2000s.<\/p>\n<\/div><\/div>

Capabilities<\/h2>\n<\/div><\/div>

The QR code can include a lot of information, as it can contain 7089 numeric and 4296 alphanumeric characters, which corresponds to half a page of A4 text. This is in contrast to the barcode that can be found on items in shops, which contains between 10 and 13 characters at most.<\/p>\n<\/div><\/div>

The two types of QR code<\/h2>\n<\/div><\/div>

Static QR code<\/h3>\n

Static codes do not allow for the collection of follow-up data and are generally used when the information does not need to be updated. This is because the content of the QR code cannot be changed after it has been designed. As the information contained in the code is fixed, it is mainly suitable for private use to transmit an email address or contact details for example.<\/p>\n

Dynamic QR code<\/h3>\n

Unlike a static QR code, the information in a dynamic QR code can be changed after it is created, even when it is printed. Dynamic code is more secure, as it can be password protected. In addition, it can display statistics on the use of the QR code, including the number of scans, the date of the scan, information on the devices used and geographical information.<\/p>\n

The dynamic QR code will be more suitable for companies whose information needs to be updated regularly or as part of a marketing strategy.<\/p>\n<\/div><\/div>

Is a QR code reader already integrated in your smartphone ?<\/h2>\n<\/div><\/div>

To find out if your device has QR code reading functionality, you can test it using the QR code below. <\/p>\n

Simply open your camera application and position the camera of your smartphone or tablet on the QR code as if taking a photo. <\/p>\n

A notification should appear if your device is able to read the QR code. By clicking on the link that appears on the screen, you will be redirected to our MCA Concept website.<\/p>\n<\/div><\/div>

In the event that a code reader is not directly integrated into your smartphone, you can download a free third-party application for iPhone from the Apple store<\/font><\/u><\/a> or the Google Play<\/font><\/u><\/a> platform for Android.<\/p>\n<\/div><\/div><\/div><\/div>

QR code security<\/h2>\n<\/div><\/div>

The QR code may be subject to malicious or fraudulent use.<\/p>\n

In order to obtain better protection, to avoid scams, it is essential to scan a QR code with care. Instead of using your phone's camera, it is recommended to download a security application that protects against QR codes containing dangerous links. The Kaspersky QR Code Scanner<\/font><\/u><\/a> application for Android or Kaspersky QR Scanner<\/font><\/u><\/a> for iPhone, for example, is available to scan QR codes safely. This application warns when a QR code contains a dangerous link or redirects to a malicious site.<\/p>\n<\/div><\/div>

What is the purpose of a QR code ?<\/h2>\n<\/div><\/div>

A QR code can be used to quickly display all kinds of detailed information about a product, a promotion, a company, an event or to display the menu of a restaurant. <\/p>\n

Various sectors have already adopted the QR code for several years. It can be found, for example, in the cultural, food, textile and tourism sectors and is used by companies and organisations as well as by private individuals. <\/p>\n

On 30 June 2020, the QR-invoice<\/font><\/u><\/a>, i.e. an invoice with a QR code containing payment information, was introduced throughout Switzerland to permanently replace the current payment slips.<\/p>\n

From 1 October 2022, BV and BVR payment slips can no longer be used to make payments. Invoice processing will be faster and simpler, as it will be sufficient to scan the QR code on the invoice to trigger the payment and then validate the transaction.<\/p>\n

In addition, the QR code can appear on different media, such as invoices, product packaging, tickets, on television or even on display devices in a museum. <\/p>\n

A number of data can be contained in a QR code, so it is possible to quickly transfer information to the user via a QR code, such as :<\/p>\n
