Transparent framework Making use of the geo-fence and QR code technologies the virtualised infrastructure requires integration of several key functions. Ubiquitous computing has been investigating since 1993 Weiser 1993 . The major character of ubiquitous computing is to create a user centric and application orientated computing environment Wang et al 2008 . The theory of ubiquitous computing is to integrate information from a large number of sources. By being everywhere and any time huge amount of data can be collected and process via ubiquitous supply chain. Complex algorithm and computation can be utilised in real time and only the relevant key information is then feed back to the physical systems and the stakeholders within their supply chain domain. However the theory of ubiquitous computing is difficult to extend to real physical world unless there is a schema with defined scope. We developed the system Transparent based on ubiquitous theory to manage the global logistics processes with the application of RFID mobile devices and virtualization technology. Figure 8 demonstrates the flow of information between various terminals shipping lines and Australian Customs. Using the Transparent Gateway all the public vessel and voyage details and private data container status for each carrier are synchronized. The data feedback from the private Transparent Gateway can also trigger an event which can update container status inside the each company s enterprise resources planning ERP system. Fig. 8. Overall Design of the transparent virtual framework RFID Infrastructure for Large Scale Supply Chains Involving Small and Medium Enterprises 15 The focus in Figure 8 is to keep track of each Stock Keeping Unit SKU and not on where it is coming from or going to. A clear record on the location of a SKU and trade unit number TUN in the supply chain must be kept. When an advance shipping notice ASN is received the .
