Small businesses on Viet Hung Street in Hanoi's Long Bien district have switched to QR code payments, transactions that are more modern and convenient. The move was led by members of the Ho Chi Minh Communist Youth Union of Viet Hung Ward, who introduced the ‘4.0 Street' model - cashless payments, inspired by the 2024 Youth Month movement. The Youth Union of Viet Hung Ward has deployed the 'Digital Transformation and Administrative Reform Support' team. They collect information from street businesses like bank account details and licenses to issue QR codes. Then, these young volunteers help store owners put up the codes and guide them on electronic payments. The QR codes are placed prominently at the sales location, making them easily recognizable. Buyers can make electronic payments quickly, and authorities can easily verify necessary information such as business licenses and store locations. So far, Viet Hung Ward Youth Union has distributed 150 free QR codes to street vendors and plans to expand to more locations soon. Young people in the capital are supporting small businesses to adopt QR code payments, aiming to raise awareness about digital transformation. This highlights the role of youth in the fourth industrial revolution, as we gradually build a digital government, economy, and society./.
