    Abstract: A Method for typing utilizes biometric fingerprint recognition with one hand and its thumb and fingers representing the selection of choices from 1 to 5—with thumb selects 1, index finger selects 2, middle finger selects 3, ring finger selects 4 and pinky selects 5. A touchpad with built in fingerprint reader can be used to recognize which finger is pressing the touchpad. The 26 letters will be divided into 6 groups. The first press on the touchpad invokes the corresponding group with 5 characters or symbols and the second press picks the respective character within the group. While pressing both the thumb and index fingers on the surface at the same time activates the 6th section that contains letter Z and 4 other commonly used symbols.
