A device that listens along to an elderly person's phone calls. The moment a caller sounds like a scammer, it warns them with lights and a spoken alert, then texts their family.

Phone scams targeting older adults are one of those problems that feel invisible until it is too late. Victims are often isolated, trusting, and pressured in the moment, before a family member has any chance to step in. We built ScamShield to act like a silent guardian during those calls: something that can listen in real time, recognize scam patterns, warn the person immediately, and get their family involved before money or personal information is lost. ScamShield is a Raspberry Pi device that listens to calls on speakerphone, detects scam patterns using AI, and instantly alerts both the person on the call and their family. There is no app to install and no major behavior change required.
