A muzzle print or nose print can be used as a distinguishing pattern for animal identification.[1] The muzzle print is a primary animal biometric characteristic for the recognition of individual cattle. It is a unique animal identifier that is similar to human fingerprints.[2]
Paper-based or inked muzzle print collection techniques are available.[3]
Mobile applications can also be used to collect muzzle images of cattle, for image storage as a unique digital identity.[4]
