Is there a machine which identifies finger print?

Answer 1

The FBI has a computer data base. New technology allows fingerprints to be scanned digitally and the a search for a match on the database is carried out.

Answer 2

Yes, there are multiple machines that do this. Each persons fingerprint is different, so each one is unique. These machines take a picture of the fingerprint, and compare it to the ones already saved in a computer database. It then compares the different marks in your fingerprint, and is able to identify the owner. Not everybody has fingerprints on file though, so sometimes it doesn't work out.

Answer 3

hi here is the answer for your question babes u would find it in the end!

Toxicology is the fundamental science of poisons. A poison is generally considered to be any substance which can cause severe injury or death as a result of a physicochemical interaction with living tissue. However, all substances are potential poisons since all of them can cause injury or death following excessive exposure.

The name forensic toxicology implies that the science has a legal purpose as its basis. Forensic Toxicology is defined by the American Board of Forensic Toxicology as the study and application of toxicology to the purpose of the law.

The toxicology section screens body fluids and organs for the presence of alcohol, other drugs, and poisons. If the are found, this section confirms the identification and determines the amount present.

Law enforcement officers and medical examiners submit samples to the laboratory.





Blood, urine, vitreous (the fluid from the eye), and tissue samples are analyzed for a variety of cases: (owi) operating while influenced, drugged driving, possession of controlled substances, attempted murder, death investigations, accidents, and sexual assaults.

Blood and urine samples are often submitted to determine if a driver was impaired at the time of arrest. Both urine and blood samples are screened for the presence of alcohol by gas chromatograph.



If alcohol is present, the amount is simultaneously determined by the same instrument. The gas chromatograph separates mixtures on the basis of their distribution between a stationary phase and a moving gas phase. This technique is widely utilized because of its ability to resolve a highly complex mixture into its components within a time period that is usually measured in minutes.

A screening test is a rapid, relatively inexpensive presumptive test which can tentatively identify common substances of interest. It is often applied to an entire batch of specimens from various donors. It yields either a negative (not detected) or a presumptive positive result. Negative screening results are reported out immediately. Positive results are analyzed further by appropriate confirmatory tests. Urine samples are screened for the presence of other drugs by an immunoassay method using an instument called the called the AXSYM.

or by TOXI-LAB, a thin layer chromatography system.



A confirmatory test supports (corroborates) the screening test result, the presence and identity of the analyte (s) is established with certainty, and then the analysis is complete with respect to the identified substance(s).

If the toxicology sample is positive on the screening test, an attempt is made to confirm its presence on the gas chromatograph / mass spectrometer.

Gas Chromatograph Mass Spectrometer

After the separated sample component leaves the column of the gas chromatograph, it enters the mass spectrometer, where its bombarded with high energy electrons. This bombardment causes the sample to break up into fragments, producing a fragmentation pattern or mass spectrum for each sample. For most compounds, the mass spectrum represents a unique "fingerprint" pattern that can be used for identification.

After evidence is analyzed the results are written in a report. There's always a possibility for the analyst to be called to testify in court on any one of the analyzed cases.

Answer 4

yes there is, the finger print is read by a scanner, and the fingerprint works like a password. there are many fingerprint reader for sale, they can come built in a laptop or bought seperatly.

Answer 5

All sorts. Search on fingerprint scanner.

Answer 6

Yes there is .

u should see that CID SERIAL on Sony ent . every friday 10:00 p.m in India.

Answer 7

YES, DEAR THERE IS A COMPUTER DATA BASE SOFTWARE WHICH INSTALL IN COMPUTER THE WE CAN IDENTITFY ANY TYPE OF FINGER PRINTS.

Answer 8

yes. try the following web page

Answer 9

Many. You can even get ones to use instead of passwords on your computer now.

Answer 10

Yes. It is called a computer.
