What is an Inkless Fingerprint?
An inkless fingerprint is a clean, modern method of taking a fingerprint. With this type of individual identification, the messy inkpads of the past are no longer necessary. A special inkless fingerprint pad is used to take impressions, rather than a traditional inkpad. Sometimes, special paper is also used to record prints.
Employers frequently opt for inkless fingerprint systems, which can assist them in performing background checks on potential and current employees. By eliminating the mess of traditional fingerprints, inkless systems can be more convenient and easy to use in a variety of settings. Occasionally someone who has been fingerprinted in this way will need to rub his or her fingertips together, or wipe them with a paper towel, to remove trace amounts of chemical residue. This can be left on fingers due to chemicals necessary for this fingerprinting process.
Inkless fingerprinting utilizes special paper and a chemical reaction to produce a detailed print. Towelettes or a special inkless pad are used in place of traditional ink pads. When fingers coated with these chemicals are pressed onto reactive paper, an image forms. Other forms of inkless fingerprinting may utilize digital technology in place of chemicals and reactive paper.
Taking a digital inkless fingerprint typically is done much like digital scanning. Fingers are pressed onto a small scanner attached to a fingerprinting software program. The scanner photographs finger pads and records prints along with other information like the person's name, address, and date of birth. Often, the same program is used to store facial photographs known as mug shots.
Chemical inks can also be used to capture an inkless fingerprint. Fingers are pressed into ink laced with chemicals that develop under heat. Fingerprint cards are then baked and the inkless fingerprint is revealed.
Inkless fingerprints are often used to add another level of security to checks or other documents. Banks may take a thumbprint and use it to verify personal identity for banking transactions. According to statistics, incidences of checks being endorsed by the wrong people are drastically reduced when thumbprints are used. Inkless fingerprints may act as a powerful deterrent to criminals who try to write bad checks or assume another person's identity.
Notaries and medical labs also make use of inkless fingerprints, which provide a clean system of recording proof of identity. For industries where sensitive information is handled, inkless fingerprints can be a necessary part of doing business and maintaining security. For those who work with confidential papers or health and financial information, the addition of a fingerprint to personnel records can be a very wise method of record-keeping.
What are 3G Networks?
Third generation or 3G networks represent an international standard for wide-area cellular networks that are replacing 2G networks. The main advantage of these networks is use of a wider radio spectrum resulting in faster data transmission for advanced multimedia services and a larger network capacity. Carriers can deliver these advantages at a reduced cost compared to 2G network technologies, though physical implementation of a 3G network can be expensive in some cases.
3G networks represent the natural evolution from previous standards. Increasingly cellular phones and handheld mobile devices have incorporated additional services to telephony. Today’s mobile devices offer high-speed World Wide Web access, emailing, messaging, video phone and multimedia services. People want to be able to watch streaming movies on their cellular phones, download and play music, store data and share files with other cellular users. 3G networks offer faster, slicker ways to do this.
These networks have been in operation globally since December 2005 and are continuing to spread. Some telecommunication companies in the U.S., Canada, Asia and Europe use a flavor of 3G called W-CDMA (Wideband Code Division Multiple Access). Others use CDMA2000, a non-compatible, competing 3G standard that includes a small family of protocols. These are known as CDMA2000 1xRTT (1 times Radio Transmission Technology), CDA2000 EV-DO (Evolution Data Only), and CDMA EV-DV (Evolution Data/Voice). Two popular mobile carries that use CDMA technology are Sprint and Verizon.
If your mobile phone utilizes a subscriber identity module or SIM card, your carrier is using a GSM (Global System for Mobile communications) network. GSM networks make the switch to 3G networks by first incorporating a General Packet Radio Service (GPRS). From here the network can be converted to a Universal Mobile Telecommunications System (UMTS), a 3G standard sometimes referred to as 3GSM. Alternately the network can incorporate an Enhanced Data rates for GSM Evolution (EDGE) system, though some people consider EDGE a 2.75G system since it is slightly slower than other 3G networks.
In practical terms, if you are looking for a GSM mobile phone carrier and that carrier offers UMTS or EDGE, you know you are getting a 3G network. Alternately, if considering CDMA carriers, look for one of the CDMA2000 flavors mentioned earlier. Be alert for newer technologies as well. As you might have expected, there is already talk of 4G networks, and protocols will continue to evolve with time to define newer standards.
