Abstract
A breath alcohol device calibration system includes a computerized calibration module operable to calibrate a breath alcohol device, and an interface operable to couple the breath alcohol device to a remote server. The interface uses a connection employing a cryptographic function such that data stored on the breath alcohol device can be securely transferred from the breath alcohol device to the remote server using the calibration system. The interface is further operable to transfer data stored on the breath alcohol device from the breath alcohol device to the remote server directly without storing the data in nonvolatile storage on the calibration station.
