RFID allows for data capture without human intervention, and where many tags may be sensed at once, but these also make RFID data capture significantly more complex than reading bar codes or human data entry. A data-capture infrastructure must be concerned with managing the tag-to-reader communication channel, filtering unwanted information, combining reads from multiple interrogators, keeping a reader infrastructure running properly while unattended, and managing the interaction between interrogators and other physical elements of the data-capture environment. This session will explore how to architect a well-layered software system that separates these concerns, so that each may be managed effectively. Such understanding is essential to selecting and deploying the many commercially available data-capture hardware and software products on the market. The presenter will also introduce several data-capture standards, including LLRP, ALE, RM and DCI.
