A NTUA Diploma Thesis titled “Preferences of Public Transport passengers towards contactless bank card payments” was recently presented by Konstantinos Fotopoulos. To achieve this objective, data collection was conducted through a questionnaire with focused questions, completed by a large sample of commuters. Subsequently, binary and multinomial logistic regression models were developed. Results indicate that as the difficulties in purchasing tickets decrease and payment security is ensured, passengers are more likely to adopt the new payment and boarding system. In particular, those who seek information about the new system are more likely to embrace it, as they recognize its benefits. Access to information and familiarity with contactless payments play a critical role in strengthening their confidence, making them more open to new payment practices, such as using bank cards or digital wallets.
