Google search behavior on QR codes in France peaked in the summer of 2021, with interest in the topic being far less high in 2022 and 2023. QR codes have different utilities, but in this context, they are mainly associated with contactless (tap to pay) payments with smartphones or wearable devices. In the case of France, however, QR codes are an important feature within “TousAntiCovid”—the coronavirus app that tracked vaccination certificates and recovery. The mobile app became mandatory in the summer of 2021 when wanting to travel or visit museums, restaurants, or other public areas. Domestic transaction figures for QR payments are difficult to find, making it difficult to separate whether the interest in the QR code topic stems from the coronavirus app or from a genuine interest in QR, for example, payments. Most figures on the topic come from consumer surveys and focus on the share of respondents who used such a payment method or not. As of November 9, 2025, interest in QR codes remains steady at a value of **.
