The use of mobile phones can impair the proper functioning of electronic equipment. This is particularly the case in security areas, where the use of mobile phones is often prohibited. Enforcing  the ban can only be guaranteed if the use of mobile phones can be verified.

mobifinder® is an innovative and simple to use mobile phone detector which securely identifies  and records mobile phone signals in a restricted area. Personnel in the security area equipped with mobifinder® receives an alert as soon as a mobile phone begins transmission.  Appropriate security measures can then be put into effect.
