Highlights

• SAP XI for open connectivity

• SAP All as one tool for RFIDand other automatic data

collection

• Both Java and ABAP

technology in one system

• Integration of RFID in your

currently installed backend

systems

The SAP RFID solution package comprises software components for enabling customers to useRadio Frequency Identification (RFID) with their currently installed backend systems.

SAP Auto-ID Infrastructure

The SAP Auto-ID Infrastructure, optionally together with adapters for SAP backend systems and/ or SAP Supply Chain Event Management, supports the integration of RFID interrogators andother hardware for automatic identification with backend systems. The SAP Auto-IDInfrastructure could be described as a kind of middleware for RFID and Automatic Identificationintegration.In contrast to the adapters this component is implemented as an independent system. It isconnected to the device controllers of the RFID readers. The SAP Auto-ID Infrastructure receivesbusiness-related information (indirectly) from the SAP ERP or other systems and translates it intotechnical information for the readers, handles the actions to be executed, receives messagesabout read tags, decides on the reaction to read information or missing reads, and deliversfiltered and comprised information back to the backend system.

Instead of connecting SAP Auto-ID Infrastructure directly with different backend systems it isintegrated using SAP Exchange Infrastructure. This makes it possible to use an openXML message interface on the SAP Auto-ID Infrastructure side and to easily connect backendsystems that are not SAP ERP.

SAP Exchange Infrastructure

Based on a native Web infrastructure that leverages open standards, SAP ExchangeInfrastructure (SAP XI) makes it possible to manage the broad diversity of highly heterogeneouscomponents from a multitude of vendors and running in various technology environments.The integration capabilities capture shared business semantics and act as a mediator betweenthe services and their technical realizations. It includes technical functions, such as Web servicediscovery, queuing, mapping, and routing.SAP XI-based process integration removes the problems of direct connections by extractingshared collaboration knowledge. These shared business semantics ease the integration of bothexternal and internal components. Instead of directly coding point-to-point interfaces for eachnew component, the exchange infrastructure allows instant plug-in of new components once percomponent. This provides the future flexibili ty needed in today’s fast-changing business world,

SAP SCM - Web Communication Layer

Java-based SAP front end which offers information access and full supply chain visibility for

SAP EM via the Internet.

AEPEX’ RFID Demo

For business applications using RFID the application has to communicate directly with the vendorspecific library, which processes data on a byte level. These libraries have different interfaces,different error handling capabilities and often also are only available in specific programminglanguages.The intention of the low level interface description is to unify all these vendor specificfunctionalities under a common Java interface. The level of the interface is quite similar to vendorspecific interfaces: methods to open and close the connection, read and write bytes (vendorspecific interfaces often have methods to read and write only memory blocks depend on the tag)and some basic error handling capabilities.For their “RFID Lego train” demo, AEPEX has developed a low level interface for the LRP75

Passive Reader/Writer from EMS. This reader uses a frequency of 13.56 MHz and has, togetherwith the EMS LRP-L2666 tags, a guaranteed operating range of 50.8 mm.
