Michael Yim, founder and chief executive officer of Breathometer, said the company began taking preorders for the product Wednesday and will begin shipping the keychain-size devices during the summer if it can raise $25,000 in starter funds on website Indiegogo, Tribune Newspapers reported Thursday.
Those donating $20 or more will be among the first to receive the devices, Yim said.
The Breathometer plugs into a smartphone's headphone jack and users blow into it, creating data that are sent to an app on the phone.
"Breathometer wasn't created just to address the risks associated with drinking and driving," Yim said, "but to help people, their friends and family, all to make smart and safer choices when consuming alcohol. Real-time BAC [blood alcohol content] measurement is the first step."
