Which finger is most suitable for reaching high performance recognition?
In principle, every finger is suitable to give prints for authentication purposes. However, there are differences between the 10 fingers, which are expressed in different performance for FAR, FRR and FTE. These differences are based on: • different finger qualities (use, moisture, …) • different sizes • different ergonomics (e.g., systems ergonomically optimized for the thumb are only usable by other fingers with contortion) whereby the type of sensor also reacts in specific ways to these differences. In most cases one can assume that the index finger obtains the best performance regarding FAR and FRR.
