Based upon the theory of diffusion of innovation, we examined the diffusion of various electronic banking technologies, such as ATMs, debit cards, smart cards, direct deposit, and direct payment, along with the characteristics of adopters and non-adopters of those technologies. Using the 1995 Survey of Consumer Finances we found that, in general, more educated, more affluent, and younger consumers who are likely to communicate with professional information providers tend to adopt electronic banking technologies more readily than their counterparts. However, the specific factors that describe adopters and non-adopters vary across different types of banking technologies.
