QR codes, or Quick Response codes, are two-dimensional barcodes that can be scanned using a smartphone to quickly access information or services. In the context of metro systems, QR codes are often used as a form of ticketing, allowing passengers to pay for their journey digitally and avoid the need for physical tickets.

One of the most notable implementations of this technology can be found in the metro systems of São Paulo and Shanghai. In São Paulo, the QR Code ticket does not have a validity period, but it is recommended to be used within three days after issuance to avoid damage12. Meanwhile, in Shanghai, the Metro by T-Mobile network has introduced eSIMs, which are essentially digital SIM cards. Like a SIM card, an eSIM provides your connection to the Metro by T-Mobile network3.

The use of QR codes in metro systems offers several benefits. Firstly, it provides a more convenient and efficient ticketing process for passengers. Instead of needing to purchase a physical ticket, passengers can simply scan the QR code on their smartphone to pay for their journey. This not only saves time but also reduces the need for physical contact, which is particularly beneficial in the context of the Covid-19 pandemic.

Secondly, the use of QR codes can also provide valuable data for metro operators. By tracking the use of QR codes, operators can gain insights into passenger behavior and usage patterns, which can be used to improve services and operations.

However, the use of QR codes is not without its challenges. For instance, issues can arise if a passenger’s smartphone is out of battery or if they do not have a smartphone. Furthermore, there are also concerns about data privacy and security, as the use of QR codes involves the collection and storage of passenger data.

In conclusion, the use of QR codes in metro systems represents a significant advancement in digital ticketing. While there are challenges to overcome, the benefits of this technology in terms of convenience, efficiency, and data collection make it a promising solution for the future of metro systems.
