The POS monitor-mounted keypad is one of five Model "M-e" successors to the Model M7/M8/M9/M11 family of POS input devices and is a compact 32-key keypad. This smallest member of the "M-e" family typically mounted on the right side of various IBM SurePoint point-of-sale touchscreen monitors. In its default layout, 31 of the 32 keys are individually discrete, typically featuring a numeric keypad with a zero key taking up two key positions (hence 31) and a Ctrl key on the lower 4x4 key bank. Unlike most other IBM POS input devices, all the keys are single-unit sized. After Toshiba acquired the IBM Retail Store Solutions division in 2012, Toshiba Retail continued producing these under their own branding.
