For a person having severe allergies to any particular type of food, it is important for them to carry around EpiPen, which is nothing but the epinephrine injection that is life saving in such cases.

There is a built-in temperature sensor to make sure the epinephrine stays fresh. If the EpiPen is used up, the Veta case recognizes that it’s been opened and immediately sends alerts including the GPS location of the user, to pre-selected people, like parents and school nurses.
The device also goes through a safety confirmation routine, starting a countdown after the pen is activated. If the user is not responding to prompts from the application, it will eventually issue a loud notice to anyone around explaining the situation and calling for help. Interestingly, if you plan to be traveling aboard, the settings in the application can be modified to issue warnings in other languages.
