Magnetic Stripe Reader - A Popular POS Component

Magnetic Stripe Reader & Cards An Essential Tool for Your Business.
Magnetic Stripe Reader is a point-of-sale (POS) device used for interpreting data encoded on a magnetic stripe card.
Millions of magnetic stripe readers, magnetic stripe check readers are installed worldwide. Magnetic stripe reader is used mostly for security and financial transaction purposes. They are also used in financial institutions, retail stores, telecommunication companies, kiosks, gaming, transit, schools, sports and recreation facilities and clubs for identification and transportation purposes.
The magnetic stripe readers are available in different models and sizes. A full size magnetic stripe reader comes with built-in keyboard wedge interface which are able to read credit card information directly into a PC s draft capture program.
A magnetic stripe reader comes in various interface formats - RTTL, RS-232, USB/keyboard and keyboard wedge interfaces.
Magnetic stripe reader and cards are manufactured in accordance to ISO specifications like - ISO 7810, ISO 7811, ISO 7812, ISO 7813, and ISO 4909. These specifications define the physical properties of the card, including size, flexibility, location of the magstripe (magnetic stripe), and magnetic characteristics.
Magstripes come in two varieties: high-coercivity and low-coercivity. High-coercivity magstripes are harder to erase, and therefore are appropriate for cards that are frequently used or that need to have a long life. Low-coercivity magstripes require a lower amount of magnetic energy to record, and hence the card writers are much cheaper than machines which are capable of recording high-coercivity magstripes. A card reader can read either type of magstripe, but a high-coercivity card writer may write only high-coercivity cards, while a low-coercivity card writer may write only low-coercivity cards.
In most magnetic stripe cards, the magnetic stripe is contained in a plastic-like film. The magnetic stripe is located 0.223 inches (5.66 mm) from the edge of the card, and is 0.375 inches (9.52 mm) wide. The magnetic stripe contains three tracks, each 0.110 inches (2.79 mm) wide. Tracks one and three are typically recorded at 210 bits per inch (8.3 kbit/m), while track two typically has a recording density of 75 bits per inch (3.0 kbit/m). Each track can either contain 7-bit alphanumeric characters, or 5-bit numeric characters.
Magnetic stripe reader(s) are used in very high volumes in the mass transit sector, replacing paper based tickets with either a directly applied magnetic slurry or hot foil stripe. Slurry applied stripe cards are generally less expensive to produce but are perceived to be of lower quality. These cards typically would not comply with the standards for payment and other cards mentioned elsewhere in this article.
Due to frequent use these cards suffer from damages. That s why the digital recording on the stripe is in a very low-density format and often duplicated several times in case part of the stripe becomes damaged.
A magnetic stripe reader works by reading the magnetic tape adhered to credit cards, badges, permits, passes and tokens. The information in the magnetic tape can range from account information, credit information etc. The tape is read by the magnetic stripe reader incorporated into ATMs, identification readers and payment terminals and forwarded to the central data processing services.
An USB magnetic stripe reader can be programmed to divide, rearrange, edit, and validate data. They automatically distinguish AAMVA and CA DMV data formats. They provide exceptional functionality and value in the smallest possible package, and are able to read upto two or three tracks of information with a single swipe in either direction in an easy to use standard-length slot.

Creating SEO friendly URLs

If you own a site, you should know that without a search engine optimization, or SEO, a web site has no value, and is less likely to get indexed by eerie " spiders & quot; search engines, and will ultimately suffer in the ranking. What is the end result? Poor conversions. Your site sure does not deserve such treatment. One way to ensure this is the use of SE-friendly URL-addresses. Search engines can be very picky where addresses and get dizzy when they face a long confusing URL. They prefer to see the URL, which do not have long lines of inquiry. Our intention is to search engines happy.
Static URLs
SE-friendly URL-address URL, are those that are easy to remember for the visitors and just spidered. Dirty URL (dynamic) are a thing of the past and slowly, people realize the importance of clean URL-addresses (static). For example, URL type:
http: / / www.lookatthis.com/2/best-products
gets indexed much faster than
http: / / www.lookatthis.com/2/cgi-bin/gen.pl?id=2& view url = best
A dynamic May deceive search engines, and as a result of your rating will hit low.
URL Length
At basic level, URL, which are friendly SE, are those that are keywords, added to them. Make them as short as possible, as many phrases as possible that are relevant. Do not forget to use keywords that you would like more goals. Web user should find it relevant and easy to enter and should not be too long. Just as the physical address short easy to remember, the same way it must have greater visibility and be easy for visitor remember.
Hyphens in URLs
There is another aspect of good SE-friendly URL-addresses. Do not use to connect to emphasize words and instead use a hyphen. This is the pain of all those typing in the URL and underscores not only that; URL without underscores getting better seen in the search engines. For example, URL, as " SE friendly " will appear only when the user enters that way, and this is clearly not how we type key words when searching. At that time, URL, such as " SE friendly & quot; or " SE-friendly & quot; happens to manifest themselves much better on search engines and provides more visibility.
Use lower case letters Letters
Using URL, also helps. Never before URL-addresses of all upper or hint of capital letters in them. We all know that people do not use the letters when searching for something. Despite the fact that most servers are not sensitive, you would be a problem if they were.
URL Rewrite
If you already have a web site, you will have to rewrite the URL, to cover all these discrepancies. How can we do this? Rewriting URL means the establishment of a system on the server, which will understand and interpret the new format URL. What happens is that we are actually making them dynamic and static. This means that URL, which had previously requested rows will be replaced by a slash and simple layout. There are several free tools that can be used for rewriting URLs.
Conclusion
Having static SE-friendly URL-the address could lead your site on the right track and help in search engine optimization. SE-URL-friendly web site will make you more visible to visitors and enables search engines to find it too easy. Spend time and effort in the creation of SE-friendly URL, and you will see that the results are enormous. You will find your page and moving up a web site restoration high ranking before long. See you on top!
