Appears in the issue.

G4S Technology Limited of Tewksbury, Glou­cestershire, United Kingdom, has integrated its Symmetry Security Management software with the ASSA ABLOY Aperio range of wireless online locks. The combination allows companies to replace existing man­ual locks and wirelessly connect them to the access control system at a reasonable cost. Information is transferred between the card and the lock via a hub, which is usually located in the ceiling above the door. This provides more security than other wireless systems, because each use of a card triggers a check of the online database for access permissions. Rights can be changed without delay.
