<p>A smart card 4 is written with at least one work history object 3 which relates to a worker via a mobile electronic device 2. The smart card is provided to a contractor 5 for verification. The contractor reviews the work history objects from the smart card. If the work history objects are acceptable, the contractor may add or write an access code 6 to the smart card or validate an access code stored on the smart card. The worker can then use to the smart card at an access control system 7 which compares the access code read from the smart card to access codes stored on a database 8 and open a lock if the codes match. The access codes can be unique or standard. The work history objects can relate to health files, insurance files, criminal record files, finance or accounting information or skills accreditation files. The work history objects can be written to the smart card wirelessly, using BLUETOOTH(RTM) or NFC. The invention eases the burden of maintaining paper records on both workers and contractors. The invention is of particular use at construction sites or building sites.</p> |
