Fingerprint and Other Impressions

One of the most important aspects of being a fingerprint examiner is determining Henry’s classification number. To come up with Henry’s number, you first have to fill out and extract patterned information from a 10 digit card (also called blocking the fingerprint cad). The second step is to calculate the Henry fingerprint value, and the […]

Secondary Classification is a subset of Henry Fingerprint System where patterns on index fingers are assigned by capital letters. Their values are set after the primaries in the classification line. In some special cases, a special extension to secondary i.e. small-letter grouping is used. Before jumping on how to calculate the value of a fingerprint’s

I’ve used stamp pads and fingerprint ink pads hundreds of times. They appear to be the same but forensically, both are different. And you should be aware when using a regular stamp pad for fingerprint registration. So, should you use stamp pads to register fingerprints? Yes, but only for general purposes. Avoid using them for

One of the trickiest things is coming up with the Primary Classification Values of the Henry Fingerprint System. How to Use Henry Classification Calculator? I made this simple for you. The tool is very simple. It works like magic. So, try this tool and give your feedback in the comments section. Using this calculator, you

Key classification is the last subdivision of Henry Fingerprint System, mainly used by the FBI, USA. Here, ridge counts of the very first loop of the 10-digit card are used as the key division values, except loops on the little finger. And their values rest at the beginning of the classification line. The above is

Primary classification is the first division for classifying fingerprints using the Henry fingerprint system. It is also called whorl division because it uses only whorl patterns across all the fingers. Here, the values are calculated based on the summation of even and odd fingers, separately followed by the addition of one. The above para is

In Henry’s fingerprint classification system, there are 6 main divisions with 3 common extensions. Primary, major, secondary, sub secondary, final, and key classifications are the six main classifications. While the second-sub secondary, WCDX and special loop division are three extensions. More precisely, these six divisions with extensions are referred to as FBI modified Henry fingerprint
