The registration solution under this actual procurement is planned to be utilised for the registration of crews on some current venues for building and construction. The collected information shall be transferred to Oslo kommune's new system for supplier follow-up (the procurement of this is not completed). It is planned that the crew data is registered with the help of an HSE card (previously building card) issued (on behalf) of The Norwegian Labour Inspection Authority. Fixed readers for crews under this agreement are planned to be utilised mainly for the registration of crews on outdoor venues. Therefore there will be a requirement for solid readers with the ability to tolerate external influences both weather wise and in terms of vandalism. It is also appropriate to use the same readers as the fixed readers indoors, possibly in a version without the same requirements to tolerate external influences. To some degree it is also planned to use the readers as mobile readers.
