Suggested Threshold Settings | Acroprint V3, TQ600 specs

The threshold value is a global setting, i.e., it is set for all users. If a user has a problem with fingerprint verification due to worn fingerprints or dry skin you may need to have the user enter their User ID in order to match their fingerprint to their stored template. This is referred to as 1:1 (one to one) verification since they are specifically comparing their fingerprint to their stored template.

Raising the threshold increases security or the probability that a successful fingerprint read accurately corresponds to the correct stored fingerprint template. Lowering the threshold increases the possibility of a false acceptance. The correct balance is vital for maximum security as well as usability.

Notice: FAR and FRR are interrelated: For example, raising the threshold reduces FAR but increases FRR, while lowering the threshold increases FAR but reduces FRR. The threshold value can be set independently for “one to many” (1:N) matching and “one to one” (1:1) matching. The default threshold for (1:N) is 35 and the default threshold for (1:1) matching is 15.

	FRR			FAR		(1:N)	(1:1)
						(1:N)	(1:1)
	High			Low		45	25

	Middle			Middle		35	15

	Low			High		25	10
