Memory Ping


Price: $ 1500.00


Memory Ping is a software and sensor solution which, when combined with our training, allows investigators to conduct testing of suspects to determine their involvement in the crime under investigation.


Why it works

Memory Ping detects the presence of information in the suspect’s memory. There are uncontrollable physiological reactions in a guilty suspect when crime details are mentioned, reactions that do not occur in those who do not know those details. Memory Ping makes it easy for you to find out who knows this information.

If you are looking to strengthen your investigation process, please contact us for more information about the Concealed Information Test technique and our Memory Ping solution.

The Memory Ping training program is conducted in a week of lectures and hands-on exercises. When training is complete, a Memory Ping test can be conducted almost anywhere in 30 minutes or less with the results displayed immediately.

Leveraging proven technology and testing methodology, Memory Ping detects subtle and involuntary signals with known physiological reactions to recognition and deception.

Memory Ping can be used to perform a Concealed Information Test (CIT) as well as facilitate a structured interview - requires Memory Ping v2.0 or above. Testing can be even further customized using Lafayette Instrument’s proprietary polygraph software, LXSoftware. - requires LXSoftware v11.6.4.

Analysis of CIT data can be performed automatically with Memory Ping’s validated algorithm. It is based on decades of published research from several respected scientists. The algorithm can score the data, show the user what it is scoring, and will produce a decision along with a probability statement.

Reactions are detected using sensors on the hand or fingers while the software can be used on a laptop, desktop, or even a tablet. The Memory Ping software allows the user to quickly set up and conduct an interview or test, watch the data scroll on the screen in real time, evaluate the data offline, and easily send the case electronically to another investigator.
