The study also tried to identify various benefits from adopting of agency banking, among the benefits overcoming geographical limitations, reduction of queues in the banking hall, enhancement of productivity in the banking industry and Reduction of paper work are the leading benefit banks in Kenya realized from the adoption of agency. The existing opportunities for adoption of agency banking are Expansion of mobile phone users, Commitment of the government to facilitate the expansion of ICT infrastructure, Increment of educated potential customer, the relative increase of the public awareness about the service are among the leading opportunities. The study suggests a series of measures which need to be taken by commercial banks so as to address various factors affecting its adoption among them: Public awareness on the use of ICT, e-commerce and e-Payment need to be raised and enhanced. The government should also legalize the acceptance of electronic receipts as a mode of transaction confirmation. This removes the past requirement of providing paper-based receipts for cash in and cash-out transactions, in doing so the desire to use the agency banking service will rise.
