A method of tracking a vehicle during a transfer process that includes one or more stages. The method involves utilising a tag having a tag data store, and uses a tag reader to determine an identifier from the tag data store, and then uses this to determine transfer information at least partially indicative of an identity of the vehicle and a status of the transfer process. The transfer information is then used to locate the vehicle, confirm that a stage in the transfer is to proceed or determine the status of the transfer.
