Henry Classification System was developed by Edward Henry to facilitate orderly storage and faster search of fingerprint cards, called ten print cards. It was used when the ten print cards were catalouged and searched manually and not digitally. Each ten print card was tagged with attributes that can vary from 1/1 to 32/32.

-Each Finger on each hand has a number and a value. For instance the left index finger is finger #7 and has the value 2. The number and values are as follows.
-Hand  |            Left Hand            |             Right Hand
-Finger|  Pinky|Ring|Middle|Index|Thumb  |   Thumb|Index|Middle|Ring|Pinky|
-Number|    10    9     8     7     6          1     2      3     4    5
-Value |     1    1     2     2     4         16    16      8     8    4
-The first thing you have to do correlate the finger number with its minutia.
-EX)
-Finger#| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
-Minutia| W | W | L | W | A | W | A | L | A |  W |
-Where W = Whorl, L = Loop, and A = Arch minutia types.
-Next you take the value of the even number whorls.
--In this case, Finger# 2, 4, 6,  and 10
--Value of Finger# 2 is 16
--Value of Finger# 4 is 8
--Value of Finger# 6 is 4
--Value of Finger# 10 is 1
-Then we take the value of the odd number whorls.
--In this case, Finger# 1, and 7
--Value of Finger# 1 is 16
--Value of Finger# 7 is 2
-Now we add these values up
--Even
-(16 + 8 + 4 + 1) = 29
--Odd
-(16 + 2) = 18
-Then we add them to the equation
-(E+1) / (O+1)
-So now we get
- (29 + 1) / (18 + 1)
-This gives us our Henry Classification Number of 30/19
-Even if the person has no Whorls, their classification is still 1/1
-This number can now be used to narrow down the ammout of prints to compare to. Which speeds up the proccess tremendously.
