What to Do If the Iris Scan Keeps Failing in Subject One Exam?

[StEthan]

Iris scan failure may be due to distance issues or equipment problems. Each person's iris pigmentation is unique, and if the contrast is insufficient, the machine may fail to capture data. Note that an iris scan is not required for obtaining a driver's license and will not affect the normal licensing process. Below are the physical requirements for applying for a driver's license: Height: Applicants for large buses, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. For medium-sized buses, the minimum height requirement is 150 cm. Vision: Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or streetcars must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. For other vehicle types, the requirement is at least 4.9. Hearing: Applicants must be able to discern the direction of a sound source from 50 cm away using a tuning fork. Those with hearing impairments who can meet this requirement with hearing aids may apply for a license for small cars or small automatic transmission vehicles.
