WRIXO is a high-tech ID wristband. In place of words engraved directly on the bracelet, a QR code directs medical professionals to your unique profile in the Cloud. It also contains a Near Field Communication, or NFC, chip embedded inside. All first responders have to do is tap their NFC-enabled smart device to the wearable, or if they don?t have NFC capabilities, scan the band?s QR code with their phone. From there, they can access personal data such as family history, doctors? notes, current medications, emergency contacts, and blood type.
