This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication. The wedge application is an application that handles the communication withbarcode readers and converts the barcode into key presses from a virtual keyboard. The wedgeapplication is an application that the manufacturer of the barcode reader supplies. The usermust install the drivers and wedge application for the reader. On one type of the computersthe user is not allowed to install own applications. This is solved by Scania by installingdrivers and wedge applications from the largest actors on the barcode reader market.The implementation of RFID readers is not as urgent as for barcode reader. RFID is mostlyused in shape of smart labels. Smart labels are a combination of an RFID tag and a barcodeand therefore the barcode can be used on smart labels. When and if the implementation ofRFID will be made the EPC standard should be used. This is probably he standard that will beused in supply chains. The EPC standard specifies a protocol between the RFID reader andthe host computer.
