Disclosed is a process for quickly gathering accurate alpha-numeric data from keypad devices. Keypad devices such as telephones, ATMs, and point-of-sale devices do not often have associated alphanumeric entry keys (many phones do not have a Q or Z for instance) or if they do the method of entry is often slow and cumbersome (asking the user to hit a key repeatedly to signify a 'D' as opposed to a '3'). This process builds a special index of the data entry possibilities replacing non-numeric characters with a special key. The customer entry uses this special key (the key on the phone is one possible implementation) to represent non-numeric data. A sorting and matching process then matches the data entered with the possibilities generated and produces a match requiring minimal customer input. Scope and Use The scope and use of this invention can be described as follows: Customer input of alpha-numeric data is required. Customer data that is all numeric or all non-numeric is not generally improved by this process. The keypad input device does not provide quick or reliable entry of unique data. Many processes are used on keypad devices
