Fast food chain KFC has solved the worldwide problem of how to eat without staining the smartphone screen. KFC has introduced an ultra-thin rechargeable Bluetooth keyboard that is placed on a fast food tray and connected to a smartphone or tablet via Bluetooth, so that the user’s fingers full of sauce do not stain the screen when typing. At present, this KFC tray keyboard has been tested in KFC fast food restaurants in Germany, and will replace the usual oil-absorbing paper sheets in general trays.
This product is durable and can be reused after wiping clean. Now these fast food restaurants at KFC have another headache, that is, customers will roll up the keyboard and take it away after eating.
