DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a monitoring method for effecting time and/or passage checks for instance, in which individuals, such as physical persons, by contact with a so-called stamping unit (information exchange unit), supply information to said unit in which the information is preferably compiled.
The invention also relates to a system for carrying out the method.
Methods and systems essentially of this kind are known to the art. Two principal types of such systems exist.
A first of these systems includes a stamping (information exchange) machine, in which all persons clock-in and clock-out, so as to record the times at which such persons come and go. This system has a number of natural limitations, such as the number of persons clocking in and out, local systems which exclude the possibility of clocking in and out on some other machine or at some other place, reliability in operation, etc. These systems often consist of one single unit which integrates the stamping or clocking mechanism and calculating computer. A documentation printer or writer is normally connected to this unit. Person identification is normally effected with the aid of CR-80 cards provided with a magnetic strip. This type of identification process also applies to passage control systems for a lone door.
The other type of system referred to includes several stamping (information exchange) stations where people clock in and out, these stamping stations being mutually connected by means of a physical cable or by radio links, for instance. Although such systems overcome some of the drawbacks encountered with the first type of system, the cost of the cabling and of system maintenance is normally very high. Furthermore, the system requires the central equipment to be always dimensioned for the correct volumes of active features of the system, schedules, storage capacity for the numbers clocking in and out, etc. The system is comprised of a plurality of free-standing stamping or registering units which are connected to a central computer. In turn, this computer is normally connected to a personal computer in which the final computations are made and information is presented. The centrally-controlled passage monitoring system suffers precisely the same problems as the other type of system.
Thus, the known systems always have given limitations and when obtaining the system, the user must determine both structure and volumes. Although the user is able to change both structure and volumes after making the system operational, each change results in further volume limitations, while a change in the structure of the system may, in certain cases, result in a totally new system structure.
Due to installation/cabling costs, the cost of an existing system in which the user is able to "clock" in and out at several stations is very high. If, in addition, the user utilizes high memory storage volumes in the system, the costs will be still higher.
The present invention provides a method and system of relatively low cost, high flexibility, etc., and solves the aforementioned problems.
The invention thus relates to a monitoring method, such as a time and/or passage control method, where individuals, such as physical persons, make contact with a stamping unit and supply information to said unit, in which the information is preferably compiled.
The method is mainly characterized in that existing units are arranged in a decentralized system in which each unit is separated physically from remaining units; and in that unique information relating to an individual is carried by the individual himself/herself in the form of an updatable information carrier, where updating of the information can be effected upon contact with the stamping unit.
The invention also relates to a monitoring system, such as a time and/or passage control system, comprising at least one stamping unit to which information is supplied by individuals, such as physical persons, by contact with the stamping unit, wherein means are preferably provided for compiling the information.
