An allergy warning and protection system and method to proactively warn a user and protect a dependent individual, such as a child, suffering from allergies. The system comprises a beacon housed within a wearable, such as a bracelet, that is worn by the dependent. The beacon has an associated identifier that is linked to data stored on a server that corresponds to the allergy and sensitivity levels of the dependent individual with an allergy, indicating that the child is allergic to peanuts, eggs, gluten and/or other allergens. When in use, the beacon transmits identification data to a handheld device operated by a user which is utilized to retrieve the allergy and other confidential information, such as emergency contact information, from the server and to issue an alert notification to the user. In a preferred embodiment, a layer of privacy is provided so that a user must first be “trusted” before receiving confidential information about a person with allergies.
