People with visual impairments who need to make bank transfers use talking Automatic Teller Machines （ATMs）. The aim of our study is to determine user-friendly methods for making bank transfers using the numerical keypad of a talking ATM, whose procedures can be difficult for visually impaired customers to complete. Our experiment investigates four operational patterns consisting of combinations that assign three operations （multitap, cursor movement, and number inputs） to three procedures: financial institution selection, input of the initial three letters of the name of the financial institute, and a final selection from among five candidates. Twenty blindfolded-sighted and nine blind participants utilized the four operational patterns to conduct a bank transfer using a simulator. The results show that cursor movement input in the first and third operational stages and multitap input in second stage were the most useable methods for both blindfolded-sighted and blind participants.
