Reopening Tips: How to Clean POS Terminals, Drive Thru Headsets and Fingerprint Readers

With reopening on the horizon for more restaurants, cleaning is more important than ever. POS terminals are one of the most frequently used pieces of restaurant equipment, and touchscreens especially can harbor foodborne germs from employees failing to take off their gloves when switching from prep work to using the cash register.

PCAP, which stands for projected capacitive, is a touchscreen technology that requires grounding to activate. If employees are using thin food service gloves with PCAP terminals, remind them to change their gloves if they need to touch food, especially after handling cash or credit cards.

You can find PCAP touchscreens in the following POS hardware from PAR:

Many value-oriented POS terminals have 5 wire resistive touchscreens, a technology that consists of two thin, electrically-resistive layers that come into contact when someone touches the screen. As a result, employees can use gloves, a stylus, or their bare hands with these touchscreens – presenting more opportunities for viral infections to spread since there are many potential sources of contamination.

Here is how to safely clean POS hardware to prevent the spread of infection:

  1. Turn off the POS terminal.
  2. Dampen a clean towel with carbonated water or use an alcohol-based disinfectant wipe. Never pour carbonated water directly onto the terminal.
  3. Wipe down the POS system, making sure to clean all hard to reach areas.

To clean drive-thru headsets, use the following steps:

  1. Remove the battery and foam pad.
  2. Wipe down the headset with a non-abrasive antiseptic wipe or a soft cloth sprayed with disinfectant. Never spray the headset directly.
  3. Make sure you do not soak the headset or bend the microphone.

For cleaning fingerprint readers, follow these recommendations:

  1. Apply the sticky side of a piece of adhesive cellophane tape to the window and then peel it off
  2. Avoid the following:
    • pouring liquid directly on the reader window
    • using alcohol-based cleaners
    • submerging in liquid
    • using paper or abrasive materials to rub the fingerprint window
    • poking the window coating with your fingernail, a pen, or other items
