Refillable mugs and smart chips

Ran across this thread from LaughingPlace.com.  Reading between the lines, and the actual lines, it appears that Disney's refillable mugs could have embedded smart chips that can be used to enforce the refill policy.  The current policy is that the mugs are only good at your current resort and during your current stay.  But, as one poster mentions, older mugs may have been sold under a different policy (and probably without chips).

 Word has it that when they have the chip in operation, it enforces the two rules above, as well as a time limit, such as not allowing multiple fills within a 5 or 10 minute window. This is to prevent you from buying one mug for the whole family, then filling the single "unlimited refills" mug, dumping it into another glass for another family member, then immediately refilling it again. The 5- or 10-minute rule is not going to impact anyone using the mugs in a legitimate way.

This turns out to have been a big controversy about a year ago, but not much of substance has been seen lately.  The issue still generates heated discussion. The new system was tested at All Star Sports last year, using new machines from a company called ValidFill.   For more background see this post at disneydispatch.com,  or this post at passporterboards.com, or this story from mousesteps.com.  Part of the problem Disney is apparently trying to solve is people using their own containers to get drinks.  However, solving that problem may be creating new customer relations problems.  We'll no doubt be hearing more about this, especially if the new system goes into more resorts.

Well, so far we know about chips on room cards and chips on drink mugs. Short quiz - fill in the blank...
'This really________" .  Hints:  (1) "is an imaginative and helpful use of technology"  (2) "shows the Mouse is interested in what we do"  (3) ???

An aspect to all this that seems to have escaped attention is the possible consequences of having RFID sensors all over the place at WDW.  This includes the ones we know about and the ones we don't know about.  Think about gas cards, credit cards, debit cards etc. that have imbedded chips.  Let's hope that Disney has a handle on possible security problems with this technology.
