The present invention provides a portable alcohol tester with biometric and location recordation and transmission. The portable unit may use photo, retina, or fingerprint recordation while the system is testing to ensure the identity of the participant. The unit may also use Wi-Fi stations, cellular towers or global position satellites to identify a location, time, and date for the test and record said information. The unit may be equipped with RF, Wireless, cellular, or Bluetooth™ communications to transmit the test information to a remote data center. The data center is equipped to merge the various different data points received into a coordinated presentation. The test information can be used by criminal justice agencies for recording the time, date, location, biometric ID, and breath alcohol content. The same information could be used for participant monitoring or rehab institutions.
