Bluetooth devices operate at 2.4 to 2.8 GHz. There are a number of firms that offer RFID tags operating at 2.45 GHz, including Tagsense, WhereNet (owned by Zebra Technologies), Ekahau and AeroScout. The last two companies’ offerings employ Wi-Fi protocols. I am unaware of any tag and reader combination utilizing the Bluetooth protocol.
As far as publications that explore the most up-to-date advances in RFID go, RFID Journal covers everything about the technology. The only other resource out there is the Global RF Lab Alliance, which offers a publication featuring academic papers. I hope that helps.
