Contactless tickets are digital tickets that allow users to enter events or transportation systems without physical contact. These tickets are typically stored on a smartphone or a smart card, making it easy to access them without needing to print or carry paper tickets. When attending an event or using public transport, users can simply scan their smartphone or smart card at designated readers. This technology enhances convenience and reduces the risk of spreading germs, as there is no need to exchange physical tickets with staff or other attendees.
