http://trutouchtechnologies.com/index.html

• Driver places his/her finger against a scanning pad and the device detects the BAC. The device will prevent the car from starting if the driver's BAC is above a certain level
Place your ungloved finger against the pad and the IR beam senses the BAC
• The system will not be on the market in another estimated 8-10 years
• Must be installed into the car during manufacture
• Estimated to cost about $200, developed with help of a $2.25 million grant from the National Highway Traffic Safety Administration

BBackSafe is a cheaper, simpler device that is not required to be built into the car during manufacture. The TruTouch Reader will not be in the market in another 8-10 years; in the meanwhile, drivers can purchase BBackSafe, which not only prevents a drunk person from driving but also alerts an emergency contact should the individual fail the test.

• Device is a keychain that be added to car keys, has no actual interaction with car
• Can be $70 for a keychain that is +/- 0.010% at 0.080% BAC
• Does not have an emergency contact system

Unlike a simple keychain breathalyzer that relies on the responsiblity of the user, BBackSafe will actually prohibit the user from driving the vehicle since it prevents the user from starting the car. The keychain breathalyzer simply gives the user a reading of their BAC, while BBackSafe interacts with the car to restrict the user from driving. BBackSafe also has a warning system in place to alert emergency contacts.

BBackSafe is a simpler, cheaper version of the SAAB Key Fob, and unlike the SAAB Key Fob, it is not only limited to SAAB vehicles and does not need to be integrated with the car during manufacture. BBackSafe also provides a higher level of protection for drivers, as it sends a warning message to an emergency contact should the drunk driver attemp to drive the vehicle.
