Abstract
Abstract Apparatus for verifying an intended user of an identification code. An operator enters the characters of the identification code into the apparatus by a suitable device, such as a keyboard, and the entered identification code is compared for verification by a predetermined relationship among the characters of the identification code. The predetermined relationship is checked by the apparatus of the present invention to control the operation of a signalling device or a control mechanism. Each identification code comprises a plurality of sets of characters. Each set of characters includes a code selecting character and a code comparing character. There is a comparator circuit for each code selecting character position in the entered identification code. Each comparator circuit serves to compare for verification the code comparing character of its associated set of characters with the preselected code within the apparatus selected by the code selecting character of the associated set of characters. Should all the comparator circuits produce match output signals, then the apparatus verifies the user as an intended user. Should one or more comparator circuits fail to produce a match output signal, then the apparatus does not verify the user as an intended user.
