In an isolated and comfortable space, the Acclair member goes through the Brain Fingerprinting test. In a one-minute test, s/he is exposed to a series of visual and sonic stimuli aimed to stimulate the P300, a brainwave response to a definite recognition of the stimulus shown.

In accordance with the Neurocapital™ methodology, the Acclair test is divided into security-related events and marketing-related bits of visual information. The results of the test determine whether or not the member is allowed to proceed onto his/her flight, and the summary of his/her brain reactions are evaluated to establish the extent of rewards received.
