Fingerprint equipment generally refers to various tools and devices that are used to collect, identify, classify, or compare fingerprints. For example, forensic science investigators can use this equipment to collect evidence from a crime scene. Other applications can include security and hobbies. There are many different types of fingerprint equipment, such as ink, pads, paper, magnetic strips, and fiberglass brushes.
Fingerprints are the impressions made by the epidermal ridges on a human fingertip. Since every individual has unique fingerprints, they can be an invaluable tool for investigative purposes. Fingerprinting has been used to identify individuals for a very long time. The science of fingerprinting is also known as dactyloscopy.
Ink is a common substance that is employed to collect fingerprints. The type of ink used can be important, as different inks have different properties. For example, certain inks may dry quickly, which can mean that they are less susceptible to smearing. This can be very important when trying to collect the most accurate set of prints. Two of the most common kinds of ink used in fingerprinting are porelon and black printers’ ink. Fingerprint equipment, such as inkpads, ink strips, and ink rollers all use ink to collect fingerprints.
Fingerprint ink strips generally consist of two strips of plastic between which ink is placed. One strip is removed to collect the prints. Many of these strips specify the maximum number of prints they can collect. This type of equipment is often used for gathering prints at a crime scene.
As the name implies, an ink roller is a roller, with an attached handle, that is covered in ink. These resemble a common paint roller, and the ink is applied in a similar manner. Many rollers have a folding or retractable handle, which prevents the roller from contacting a surface when not in use.
Entire fingerprint kits may be purchased. These can consist of a wide variety of items, such as inkpads, magnifying glasses, and brushes. Some kits may include canned air, which may be used to clear away dust. This allows the dactyloscopist to acquire a cleaner sample of prints. Many also include a foldable fingerprint table, on which the equipment can be placed.
Biometric devices are a type of fingerprint equipment used for security purposes. Using these, a fingerprint register of authorized personnel is kept on file by a central computer. By scanning the fingerprints of a person, the computer can compare his prints to the register, and grant the individual access to a location, or not.
