London - An iPhone case has been developed with a built-in breathalyser.
Users breathe into a test hole in the case and readings pop up on a display seconds later.
Hiroyasu Yamamitsu, boss of Japanese firm Thanko which created the device, said: “After drinking alcohol it’s difficult to know whether people can drive a car or not.
“People need to check if they’re safe to drive and there’s nothing more convenient than having one built in to your phone’s case.”
However, the case should not be used as a standalone device to determine a safe driving limit, the firm warned.
The device works once users have blown into the case for three to five seconds.
After 20 seconds the reading is displayed as a percentage on the back of the case.
The display also lights up red, yellow or green to warn people if they’re over the safe driving limit.
If the screen glows red, it means it is not safe to drive, while a green screen means driving will be within the legal limit.
When the screen glows yellow, users bordering on being over the limit and should stop drinking and wait a while before checking the reading again, and getting into their car, Thanko explained.
The Alcohol Checker case also charges a phone using a built-in battery. And breathalyser is powered by the case, meaning it doesn’t drain the battery.
The current model has been designed to fit the iPhone 5, but the firm is working on versions for other phones. - Daily Mail
