all means to assemble goods for transportation, storage, handling and product protection in the supply chain which are returned for further usage, including for example pallets with and without cash deposits, as well as all forms of reusable crates, trays, boxes, roll pallets, barrels, trolleys, pallet collars and lids
NOTE 1: The term returnable transport item is usually allocated to secondary packaging. But in certain circumstances also primary packaging may be considered as a form of RTI.
NOTE 2: Freight containers, trailers and other similar enclosed modules are not covered by the term returnable transport item.
NOTE 3 The term returnable transport equipment is considered to have the same definition as the term returnable transport item within an electronic data interchange environment.

returnables

returnable units, reject or surplus goods to be returned through the system to the consignor or returnables manager

returnable units, reject or surplus goods to be returned through the system to the consignor or returnables manager

returnables manager

function that manages the supply, maintenance, and returns cycle of returnable units
NOTE: The returnables manager function can be performed by one or more of the principle actors in the system or by an independent third party.

secret key

key that is used with a symmetric cryptographic algorithm
NOTE 1: Possession of a secret key is restricted (usually to two entities).
NOTE 2: For ERI, there can be only one entity or several entities, depending on the key management policy.

security

protection of information and data against danger, damage, degradation of quality, loss and criminal activity so that unauthorized persons or systems cannot read or modify them and authorized persons or systems are not denied access to them
NOTE 1 to entry: Security has to be compared to related concepts: Safety, continuity, reliability. The key difference between security and reliability is…

NOTE 1 to entry: Security has to be compared to related concepts: Safety, continuity, reliability. The key difference between security and reliability is that security must take into account the actions of people attempting to cause destruction.

shadowing

condition where the close proximity of a vehicle/equipment interposed between FE and OBE obscures the signals, thus preventing a successful AVI/AEI transaction
NOTE: The shadowing caused by normal traffic behaviour is taken into account and overcome to provide a successful transaction. Abnormal shadowing may be caused by large or unusually shaped vehicles/equipment or by vehicles travelling…

NOTE: The shadowing caused by normal traffic behaviour is taken into account and overcome to provide a successful transaction. Abnormal shadowing may be caused by large or unusually shaped vehicles/equipment or by vehicles travelling too closely together.

small container unit

intermodal transport units which are smaller than a standard 20-foot-ISO-Standard container or CEN-swap body
NOTE: Small containers are also called medium containers or “less than container unit” (LCU).
NOTE: The size of such LCU´s will be at least one ISO- or Euro-palette.

specific vehicle identification

action or act of establishing the identity of a specific vehicle
NOTE 1: This is in contrast to vehicle vicinity identification, where the vicinity of a vehicle with a specific identity is detected. With specific vehicle identification, it is also known which specific vehicle has been identified.

NOTE 1: This is in contrast to vehicle vicinity identification, where the vicinity of a vehicle with a specific identity is detected. With specific vehicle identification, it is also known which specific vehicle has been identified.
NOTE 2: Two kinds of specific vehicle identification may be distinguished: first, localized vehicle identification, in which case the location of the identified vehicle is known with such precision that not more than one vehicle can be present at the same time at that location; second, peer communication identification, in which case the identification of the vehicle engaged in some form of communication (e.g. an EFC transaction) is established.

system operator

organization responsible for the operation of the system
