You need a touch screen that doesn't fight you. The ViewSonic TD1630-3 gives you a 16-inch (15.6" viewable) projected capacitive panel with 10-point multi-touch, and it tilts or lays flat so your staff at the counter or your students at the desk can actually use it comfortably. HD 768p resolution keeps text sharp enough for daily work. Dual built-in speakers mean you skip the extra audio setup. VGA and HDMI inputs plug straight into the hardware already on your bench. Works with Windows 7 through 11 and Linux Kernel 3.X/4.X, so it drops into whatever stack you're running without a driver hunt. The screen is scratch-resistant, which matters when it's sitting in a retail kiosk or a busy classroom and someone's elbow keeps finding it. One cable, one plug, touch works. That's the whole job
