KFC Germany has released the Tray Typer, which looks to help customers keep their smartphone screens clean while eating the food chain's famous fried chicken.

The Tray Typer is a rechargeable, super-thin Bluetooth keyboard that KFC gives its customers on the tray that serves the ordered food. The idea is that customers will connect the keyboard with their smartphones so that they can use it to continue typing on their devices without leaving behind residues from their greasy fingers on their screens.

The Tray Typer, which was supposed to be used in place of the absorbent paper towels and tissue used up every time a customer needs to clean his or her hands to type on their smartphone, looks to be durable enough to be used over and over again by different customers, only needing a good wiping to clean up the mess left behind by the previous user.

However, Serviceplan, the creator of the marketing ploy, claimed that the Tray Typer proved to be so popular with customers that when the keyboard was handed out on the first week of newly opened KFC restaurants, every one of the Tray Typer keyboards was taken home by customers.

The technology used in the Tray Typer may seem too unreal for some, but it has been around for a couple of years. In 2013, United Kingdom-based electronics firm CSR revealed a keyboard that is similarly thin and flexible compared to the Tray Typer.

KFC has been known to release crazy electronic peripherals, with the Japanese branches of the fried chicken food chain launching a combination of a keyboard, a mouse and a USB stick that were all themed with fried chicken last year.

KFC Japan also gave away iPhone cases shaped like massive fried chicken drumsticks through a promo on Twitter last year.

The company also gave away giant plush drumsticks, which had openings where customers could stick their heads into. This aimed to attract confused looks from people who passed by, but as long as the person was sleeping soundly inside the drumstick, then he would not notice the judging stares.
