Numeric keypad

Glossary

A standard phone keypad consisting of the numbers from 0 to 9 and including the signs "*" and "#".

Alphanumeric keypads are an upgrade to those and are used to enter text as well as numbers. They include alphabet characters - usually several letters are assigned to each of the numeric keys - and you can toggle their input by pressing the corresponding key several times, often referred to as "multi-tap" input.
