摘要:Turkey’s e-commerce market is rapidly expanding, and the country is ranked first in the world in monthly mobile purchases. The purpose of this study is to determine the factors that influence the adoption of online payments systems among the customers of a Turkish bank during the COVID-19 pandemic. The research model extends the technology acceptance model (TAM) by further examining the impact of 11 factors on attitude, behavioral intention and actual usage. The results suggest a strong influence of these factors on attitude and behavioral intention. Relative advantage, perceived trust, perceived usefulness, personal innovativeness, perceived integrity, perceived ease of use, health and epidemic effects, income, private sector employment and self-employment all have a positive effect on actual online payment system usage. However, perceived risk and age have a negative impact on the actual online payment system usage.
