Abstract: A transaction system, including: an entry system for reading first identification data from a first device and second identification data from a second device; and a database system for accessing payment account data of a transaction account on the basis of the first and second identification data, and requesting authorisation data for a payment transaction using the payment account data. The entry system performs an authorisation process in response to the authorisation data being received. The database system stores an authorisation record with an authorisation time in response to the authorisation data being received. A payment system can be used to read the second identification data from the second device and generate payment data representing a payment amount.

Abstract: An over-height vehicle barrier has a supporting beam mounted above a carriageway, with multiple blade-like members rotatably mounted to the supporting beam such that the blade-like members are suspended downwardly from the beam in parallel relationship and in close proximity one to another. A leading edge of each member faces oncoming traffic on the carriageway for possible engagement by an over-height vehicle such that each member can rotate about the axis of the beam independently of the other members when struck by an over-height vehicle. A further beam is engageable by the rotating members when struck by a vehicle to limit the extent of rotation about the axis of the beam and to thereby cause the members to rotate in a return direction. Engagement of the members by a vehicle generates a warning noise to alert the driver of the vehicle and the further beam itself can generate further additional noise when engaged by the rotating members.
