Point-of-Sale Keyboards

Programmable keys, card readers and touchpads

A POS keyboard swaps a typist's layout for programmable keys that fire sale functions. Many have relegendable keys, where a paper insert shows what each key does, such as a department, quantity or void. Key counts range from about 78 on compact models to well over 100 on full-size ones. Some add a three-track magnetic stripe reader along the top, which saves a USB port for loyalty or ID cards, and some add a touchpad so a separate mouse is not needed.

Interface, sealing and key mapping

Most connect by USB, and some offer PS/2 for older terminals or a combined interface. Spill and dust protection is rated by IP codes: IP54 means limited dust entry and splash resistance, helpful on busy counters. Programmable keys need a configuration tool from the maker, and your POS software must read the codes the keys send. A cable of about 6 feet is typical, so check the distance to the terminal.

Questions about Point-of-Sale Keyboards

Why use a POS keyboard instead of an ordinary one?

It gives you dedicated, relabelable keys for sale functions, a tougher and often splash-resistant build, and optional card readers. That speeds up use and reduces mistakes at a busy counter compared with a standard office keyboard.

What does IP54 mean?

The 5 means limited dust ingress and the 4 means protection from water splashed from any direction. It handles spills and wipe-downs at a counter but is not designed for immersion or jets of water.

Do programmable keys need special software?

Usually yes. A utility from the keyboard maker assigns key codes, and your POS software has to recognize them. The paper legends are separate and simply slide under the clear key caps.
