印度采购需求：触摸显示屏、触摸显示器、POS机、触摸解决方案、销售点、数字标牌

I'm looking to source a dual-screen touch POS system with a 15.6-inch display. It's crucial that the unit has a responsive touchscreen and can handle a variety of retail applications efficiently. Could you provide details on the available options, including features, specifications, and pricing? Additionally, info on lead times and warranty conditions would be appreciated. Thanks!
