Chris Vidotto showed me this case study this morning.
Normally my eyes glaze over when I see a new case study... but this one is really cool. It's for Blue C Sushi which operates a small chain of "sushi train" restaurants in Seattle.
They have used BizTalk 2006 R2 RFID to monitor the timing and contents of plates while capturing data that can detail customer purchases.
What I found really interesting was the RFID business benefits they have identified, especially around business intelligence/insight and the better quality control and customer service that resulted (after all, nobody wants to eat stinky sushi).
Check it out - If you eyes glaze over... drink more coffee.
