if possible include an auto-populate field in the device detail screen that gives instant warranty information per badge. Reports can then be ran against this information and we can advise departments when their warranties are up as a pro-active approach. I understand as of now I can make the Tracking Date my warranty expiration but that will mean manually running the serial number against the Warranty Check applet and choosing that date for all my badges and moving forward. I can see warranty tracking becoming more of an issue as we move forward with 2 and 3 year warranty buying options. When I receive replacement RMA badges back from Vocera I understand the warranty is assigned based on the returned broken badge. A unit may receive a replacement badge back that now has a different warranty expiration date then what they originally purchased.
