About

Retruster's technology allows users to verify important messages, making sure they're genuine and deterring potential scammers. The technology employs users' smartphones for identity verification to ensure an email's legitimacy. Retruster can show users exactly who the email is from, when and where it was sent, if the email was opened, and how many times. Retruster's biometric software (including fingerprint, voice, and facial recognition) comes in a simple and powerful interface. The service is a solution to help stop email fraud by assessing incoming emails for possible signs of fraud, providing information to decide whether fraud may have occurred and take action. Retruster aims to curb the billions of dollars of fraud generated by fake emails on a daily basis.
