Abstract

A monitoring method, such as time and/or passage monitoring method, in which individuals, such as physical persons, make contact with a stamping unit and therewith supply information to the unit, in which the information is preferably compiled. The method is mainly characterized by arranging existing units in a decentralized system in which each unit is separated physically from remaining units; and is further characterized in that each individual himself carries an updatable information carrier which includes unique information personal to the individual concerned, wherein updating of the information carrier can be effected upon contact with a stamping unit. The invention also relates to a system for carrying out the method.

Claims

1. A monitoring method, including individual attendance data, in which individuals make contact with an information exchange unit and supply information to said unit, in which unit said information is compiled, the method comprising:

arranging existing information exchange units (2,3) in a decentralized system in which each said unit (2,3) may be separated physically from remaining units;

providing that each individual carries an updatable information carrier (4) which includes unique information personal to said each individual; and

effecting updating of the information carrier by contact with said information exchange unit, providing and enabling the information carrier to carry additional information, intended to be supplied to an information exchange unit; and

further comprising reading the information carried by the information carrier (4) by means of a read unit (3'"'"') for central processing at desired points in time.

2. A monitoring method as defined in claim 1, wherein said additional information intended to be supplied to an information exchange unit is information suited for passage control purposes.

3. A method according to claim 1, further comprising carrying the information on a readable and writable data medium (4), selected from a group of data medium consisting of at least a smart card, a tag, and a key.

4. A method according to claim 1, further comprising, in appropriate cases, causing contact by an individual with an information exchange unit (2) to result in the processing of desired information by means of a calculating unit (16) belonging to said information exchange unit.

5. A method according to claim 1, further comprising the step of carrying by the information carrier (4) of individual attendance data which is updated upon contact of said information carrier with an information exchange unit (2), as the individual concerned comes and goes.

6. A monitoring method, including individual attendance data, in which individuals make contact with an information exchange unit and supply information to said unit, in which unit said information is compiled, the method comprising:

arranging existing information exchange units (2,3) in a decentralized system in which each said unit (2,3) may be separated physically from remaining units;

providing that each individual carries an updatable information carrier (4) which includes unique information personal to said each individual; and

effecting updating of the information carrier by contact with said information exchange unit, providing and enabling the information carrier to carry additional information, intended to be supplied to an information exchange unit;

wherein existing information exchange units (2) are arranged in a decentralized system, which forms part of a centralized system (7); and

causing the information carrier (4) to be influenced upon contact with the centralized system (7) and therewith adapted to the decentralized system (1).

7. A monitoring method as defined in claim 6, wherein said additional information intended to be supplied to an information exchange unit is information suited for passage control purposes.

8. A method according to claim 6, further comprising causing the centralized system (7) and also the decentralized system (1) to include passage control, wherein a boundary structure is included in the centralized system and including at least one decentralized systems arranged in connection with the boundary structure.

9. A monitoring system comprising:

at least one information exchange unit to which information is supplied by individuals by contact with the information exchange unit, and which system also includes devices for compiling such information, and including existing information exchange units (2) arranged in a decentralized system (1), in which each information exchange unit (2,

     3) may be independent from and separated physically from remaining information exchange units (2,

     3) in the system;

wherein the system also includes individual updatable information carriers (4) by means of which respective individuals carry attendance information which is unique to the individual concerned;

wherein updating of the information carried by the information carrier is effected upon contact with a information exchange unit (2) which is intended to perform said updating and wherein the information carrier is intended to carry additional information;

further comprising means including a read unit (3'"'"') for reading information carried by an information carrier to enable central processing of that information.

11. A system according to claim 9, wherein the information carrier (4) has the form of a readable and writable data medium (4), selected from a group of such medium consisting of at least a smart card, a tag, and a key.

12. A system according to claim 9, wherein a calculating unit (6) is provided in an information exchange unit (2) to process desired information, upon an individual making contact with the information exchange unit through the intermediary of an information carrier.

13. A system according to claim 9, wherein the information carrier (4) is adapted to carry individual attendance information and is further adapted to be updated by means of an information exchange unit (2) upon an individual making contact through his information carrier with the information exchange unit as the individual comes and goes.

10. A monitoring system as defined in claim wherein said information carrier carries additional information suited for passage control purposes.

14. A monitoring system comprising:

at least one information exchange unit to which information is supplied by individuals by contact with the information exchange unit, and which system also includes devices for compiling such information, and including existing information exchange units (2) arranged in a decentralized system (1), in which each information exchange unit (2,

     3) may be independent from and separated physically from remaining information exchange units (2,

     3) in the system;

wherein the system also includes individual updatable information carriers (4) by means of which respective individuals carry attendance information which is unique to the individual concerned;

wherein updating of the information carried by the information carrier is effected upon contact with a information exchange unit (2) which is intended to perform said updating and wherein the information carrier is intended to carry additional information; and

further comprising a centralized system, and said decentralized system (1) and said at least one information exchange unit (2) form part of said centralized system (7), and said centralized system is adapted to influence the information carried by an information carrier as desired by the individual who has the information carrier.

15. A monitoring system as defined in claim 14, wherein said information carrier carries additional information suited for passage control purposes.

16. A system according to claim 14, wherein the centralized system (7) and also the decentralized system (1) are intended for passage control purposes, and wherein the centralized system includes a boundary structure and wherein at least one decentralized system is arranged in connection with the the boundary structure.
