Patent ID: 8598982

Claim:
A method performed by an access control device having a component configured to read data from a carrier substrate provided by a user and to grant the user access to a physical region or virtual functionality, the method including the steps of: (a) reading commissioning data from the carrier substrate, the commissioning data being applicable to a first access control device for commissioning the first access control device, the commissioning data including a first unique identifier which is applied to the first access control device upon application of the commission data; (b) applying the commissioning data to the first access control device thereby to commission the first access control device so that the first access control device operates in accordance with a wider access control environment; (c) defining a second unique identifier on the basis of the first unique device identifier; (d) writing the second unique identifier to the carrier substrate in place of the first unique identifier such that a subsequently commissioned second access control device commissioned by the carrier substrate applies the second unique identifier.
