Managing the RFID data generated is going to be a key issue in the future. All the talk now is still of read rates, the cost of tags, justifying a pilot - and then a rollout - and then the use of RFID middleware. (On the subject of middleware, see this earlier post about a proposed RFID middleware pilot in the UK)
This data management issue has been described as the iceberg under the tip, and there is a good article here that discusses it, The Four Pillars of RFID.
The four pillars are Master Data (and its management), gaining Operational Business Intelligence, the Concentration (of data in a data warehouse), and Analytics (making use of the data)
The article concludes that information management is the foundation on which RFID will ultimately fulfil or fail.
