Cloud Computing, REST and Mashups to Simplify RFID Application Development and Deployment
3 likes7,999 views
The document discusses simplifying RFID applications using cloud computing, REST APIs, and mashups. It aims to 1) simplify deploying and maintaining backend EPC systems by deploying them in the cloud, 2) enable easier mobile and web application development through RESTful APIs and real-time web technologies, and 3) enable composing RFID data and web services using a mashup editor and engine. The cloud-based approach reduces complexity and costs compared to traditional on-premise deployments. REST and real-time web technologies lower barriers to mobile/web development. Mashups allow composing RFID data and existing web services for simple use cases.
