While the U.S. credit crunch may be having its biggest impact on the housing market, the auto industry isn't far behind. U.S. auto sales are expect to match the industry's 15 year low this year, which means the country's car dealerships aren't in the best position. However, many car dealership are using a new device to help ensure their livelihoods.

In order to prevent defaults on car loans, many dealerships are turning to a new device called On Time. The small electronic box — which is mandatory is some car deals — is installed under the dash of the car and helps to ensure that car payments are made on time. As the payment date approaches, the box flashes its lights, and on the date the payment is due, emits a beep.
If the buyer fails to make the payment, the device prevents the car from starting. But if the buyer makes the payment on time, they are given a six-digit code to enter into the box to reset it.
And with the credit market showing no signs of improvement, it looks like more and more dealerships are turning to such devices. Over the past few years, Sekurus — the company that produces On Time — has grown at an annual rate of about 30 percent.
While such devices may be bad news for U.S. consumers, at least the repo man's job just got a little easier.
