While fingerprint scanners remain the default standard across citizen kiosks, an increasing number of operators are equipping their counters with single-eye iris scanners like the Mantra MIS100V2.
Why Fingerprints Fail in Rural & Farming Regions
Agricultural laborers, manual construction workers, and senior citizens frequently have worn, calloused, or faint papillary ridges on their fingertips. In hot or humid climates, sweat also causes fingerprint refraction issues, leading to repeated 'Biometric Not Matched' failures on PM-Kisan and ration distribution portals.
The Iris Advantage
Iris patterns remain stable throughout adult life and are completely immune to skin abrasions, dirt, or moisture. An iris scan captures in less than 2 seconds without physical contact, achieving a 99.8% first-attempt match rate for senior citizens.
Recommendation for Centers
Maintain at least one dedicated iris scanner at your primary authentication counter alongside standard fingerprint sensors to ensure no citizen is turned away.
