Several of our departments at one of our hospitals utilize a locator device which will cancel alarms from the nursecall system when they're in the patient's room at the bedside.  While I know that cancellations exist via callback, what I'm putting in is an idea for Vocera to implement a technology that follows what this locator device does.  This would reduce the end user's from having to carry extra/unnecessary devices, as these locator devices work via access points similiarly to Vocera devices. 

I do understand that the design/infrastructure/architecture of something like this may be complicated/proprietary to another vendor, but I'm simply posing it as a request so you're aware it's in demand.
