The Trusted Check-In program provides passive collection of geolocation data along with biometric facial verification “check-ins” to ensure the individual is in the same physical location as the device. Geofencing can be enabled to notify an officer when a person exits a specified location or enters a restricted area.

Each participant's submitted image data is never stored and never leaves their dedicated device during the check-in process. Images and biometric templates are processed in the device's operating memory, converted into Trust Stamp’s proprietary Irreversibly Transformed Identity Token (IT2TM), and immediately discarded, preventing the potential for sensitive biometric data to be misused or compromised.

The Tap-In Band is a discrete hypoallergenic band that is styled to resemble a contemporary "fitness band" and is safe and comfortable to wear. The band comes in a variety of skin tones and other colors and can be customised to each agencies preferences.

Unlike existing ankle and wrist worn technologies, The Tap-In Band has no battery, removing perennial concerns about battery failure and the inconvenience of charging, and does not itself contain GPS tracking technology thereby reducing user apprehension regarding intrusive monitoring. Removal of the Band results in the Band permanently notifying tampering even if competently repaired. The Tap-In Band leverages the GPS and NFC technologies in the user’s own mobile phone and allows the user to verify their well-being and location by tapping the band to the phone, gaining direct access to a personalized web portal with messaging and two-way audio visual communications. The use of the Tap-In Band augments facial biometric authentication using the phone’s camera and Trust Stamp holds provisional patent #63/581,409 from the US Patent and Trademark Office covering multi-factor authentication using a tamper proof band and biometric authentication.
