An arrangement is described, suitable for use at a check-in, to detect forgery and/or lies, comprising a mat upon which a passenger has to stand and with means for sending a signal. The mat comprises means to detect body abnormalities such as body sweat, agitation, hesitation and/or instability, e.g. when forged papers are handed to an officer. The arrangement may comprise devices which, upon activation, immobilise a passenger for a short time. In one embodiment, a passenger stands on the mat throughout the check-in process whilst legal documents, such as a passport, are checked by an officer. Abnormal bodily reactions elicit a signal from the device that alerts the officer. In reaction to such an alert, an optional immobilisation device may be activated. Other arrangements are also disclosed: a meter informant for informing a user of the cost of calls; a mobile mechanism for illustrating calls or SMS ("text") messages; a theft protection (or alarm) system. |
