Fingerprint scanning devices can be used for identification as well as recognition. The device has two basic functions, first is to capture the finger print image and then check whether the image matches the pre-scanned images. A typical fingerprint scanner consists of a sensor that scans a fingerprint and a processor that stores the fingerprint image and compares with the pre-scanned images in the database. The prevalent techniques deployed in a scanning device use optical sensors or capacitive sensors to capture a fingerprint image.

One of the implementation of biometrics systems that is widely accepted these days is Fingerprint door lock, as it eliminates the inconvenience of carrying keys or ID cards or memorizing passwords. The sensor of a fingerprint scanner is in constant human contact and tends to accumulate dust, grime and other foreign particles on the scanning device. With extensive usage, like any other electronic device a fingerprint door lock can get damaged. Using industry solvents to wipe the device can harm the sensitive surface of the sensor. There can be a decrease in the capture sensitivity of the sensor that may lead to failure of recognition of fingerprints. To clean the scanning surface, apply a piece of scotch tape and peel it off gently, it should remove any traces of dirt or dust from the sensor surface. If the scanner is very grimy or cloudy due to heavy usage, use a lint-free cloth or a cotton swab dabbed in mild ammonia based cleaner, rub it gently across the surface of the scanner and blot the surface dry. Do not use paper products to wipe the sensor surface and do not pour or spray any cleaner directly on the sensor. It is recommended that hands should be clean before using fingerprint scanners. Measures should be taken not to touch the surface with fingernails and sharp or rough objects.

Fingerprint scanning has proved to be boon for large organizations, especially those that follow high measures to keep their data confidential and prevent illegal access and at the same time they have provided an increased level of home security and convenience to the common man. Proper maintenance of Fingerprint scanning systems is essential to give them a longer lifespan and sustain their workability.

The usual document scanning process simply converts a paper document into an image. A single scanning can allow you to convert the file into any form, depending on how you intend to use it. More advanced printers can easily convert a page full of text into a text file that is completely editable. Having a copy of the document in this form gives you access to view, alter and convert the contents. You can use it for different applications based on the function that you require.

Many people are witness to the many benefits of document scanning and having digital copies of important documents. From a financial point of view it lowers the cost of printing or reproducing. Mailing can now be done through the internet so there is no need for snail mail. The storage of printed documents also requires physical containers. Scanning eliminates the need for space, filing cabinets and locks for protection. Another great thing is that there is no need to literally dig through countless paper sheets in finding specific information. Scanning can allow you or your office to make a database that will only require a few clicks or keyboard taps to access the necessary file. Appending existing files will also be easier. You can just attach new files to old ones and save it.

Years of document scanning has led to a lot of tips being compiled for a more efficient and error free scanning. For instance, making sure that the document you are scanning is aligned to the edges of the scanner guarantees that you need not do a repeat. Slight folds can cause blurs in the copy. If you only need the text you can scan using black and white only to make the scanner process less but faster. Lower the resolution of scanned images if you only plan in storing but not printing it. Increase the resolution if the purpose is to have it printed and blown up to big sizes. The logic is, the higher the resolution the slower it works. But if you need to send the digital file via email, opt for a higher resolution so that the person on the receiving end can print a crisp and clear image if needed.
