SUDS have been found to work on all personal devices and most public capacitive and resistive touchscreens. Some credit card terminal manufactures require use of the active stylus tethered to the screen, thus preventing function with SUDS. If you find a screen brand that is not compatible with SUDS, please let us know!

If a garbage or recycling container is not near the checkout, it is recommended to wrap SUDS in a receipt, place in an empty bag, or simply carry to the closest dispoable container, which may be located at the store exit.
