Introduction To Systems Analysis & Design

Barcodes encode numeric or textual information in a printable, machine-readable form. The use of barcodes can significantly reduce cost of warehouse management and inventory. Two main forms of barcodes exist today: Linear or normal barcodes encode data over a horizontal stretch of space or one dimension. This kind of barcode typically encodes between four and forty digits or characters. So called area codes encode data in two dimensions, resulting in much higher density which allows for up to three thousand characters to be encoded.



Most linear barcode types will only encode numbers or digits. Two notable exceptions are Code 39 and Code 128 which can also encode alphanumeric characters like letters. Two dimensional area codes usually encode numbers, letters and special characters.

The most common linear barcode type is Code EAN which is used to encode article numbers in retail. It's used throughout the world with the notable exception of the USA which uses a related code, Code UPC, for the same purpose. A special form of Code EAN carries a so called Addon, a smaller barcode next to the main barcode that can encode pricing information and the like. Code EAN with a five digit Addon is used to encode ISBN (International Standard Book Number), while Code EAN with a two digit Addon is used to encode ISSN (International Standard Serials Number).

Other notable linear barcode symbologies and their applications include Code 39 (used for pharmaceuticals), Code 128 (warehouse management and retail) and Code Two-Of-Five (warehouse management and inventory).

The most common two dimensional area codes are PDF417 and Datamatrix, both of which are used in manufacturing, package tracking and similar applications which require large data amounts to be encoded.

Barcode Checksums

To ensure safe and error free reading and scanning of barcodes, all common barcode symbologies support so called checksum or check digit schemes. A checksum or check digit is an additional character or number that is calculated from the encoded data and appended to the barcode. While reading the barcode the scanner or reader can verify the checksum and determine if the barcode was scanned correctly. This is especially important if the barcode can easily be damaged or be tampered with. Simple check digit systems like the sort that is used with most linear barcodes will only detect simple errors, like a missing character. More sophisticated systems, especially those used with area barcodes can not only detect but also repair any damage that may have occurred to the code.

Barcode Applications

Today barcodes enjoy wide spread use through all types of businesses. The first major application of barcodes was in the retail sector where the codes would encode article numbers, manufacturer data and pricing. Another prominent use of barcodes is in the transport industry where the codes carry address and tracking information. Finally, two dimensional area codes have recently gained much popularity for use in personal identity cards, drivers licenses and so forth. They are also used for the tagging of electronic parts like computer or memory chips.
Introduction To Systems Analysis & Design
The bad news is that people expect prompt replies to their email inquiries. However, unless you can figure out how to work continual twenty-four hour shifts, or hire enough people to constantly monitor incoming emails (while they're eating up your revenue), you have a problem. The good news is an autoresponder is an inexpensive - or even free -method of quickly responding to emails. What these programs do is automatically respond to incoming emails as soon as they are received.

Emails are essential to your business for many different reasons. Most importantly, these invisible email voices give you their feedback about your website - for free! However, if you

spend all your working hours answering these emails, how are you supposed to run your business? The answer is simple: use autoresponders. Autoresponders are programs that automatically respond to your emails without you so much as having to click on your mouse.

There are a number of good reasons why you need an autoresponder besides just answering your email. For example, autoresponders can be used if you need a way to send information about your services or products, pricelists, or if there are repeated questions asked across

large numbers of emails. Maybe you want to offer your site visitors a special bonus of some kind, such as advice or relevant articles. All of this can be handled by an autoresponder. Additionally, you can advertise your business and then build stable relationships with your customers by using autoresponders.

Autoresponder programs vary from software that runs with your email program to a specialized script that runs on your web hosting company's server. This kind of script may use a web page form or simply operate with your email account. This kind of script is programmed to send out

a standardized message whenever an email is received. The message is sent to a particular script or email address.

Some autoresponders can do more than simply send out standardized messages. They can send out an unlimited number of follow-up messages sent at predetermined interval of time. For example, you can set your autoresponder to send out a new message every day for as long a period as you desire.

There are numerous companies who offer autoresponders free of charge. Your website hosting company often provides autoresponders as a free service. If this is not the case with your web hosting company, there are numerous companies who offer this service for a small fee, or free of charge, providing you attach an advertisement for their company to your emails.

To personalize your autoresponder messages, you can attach a signature. Signatures in this case are much like business cards. You can include your name, company, all your contact numbers and addresses, and a brief message. It's a good idea to attach a signature to every email that is sent out. This works as a repeated reminder of your business identity every time a customer sees it. The more they look at your signature, the more likely your company will spring to mind when your particular service or product is needed.

You can create a standardized signature that every employee in your business uses, or you can go wild, and let every staff member create their own personal signature. Of course, like everything in life, there are some rules and guidelines to creating a personal signature. Keep the length of your signature between four to six lines of text, with no more than 70 characters in a single line. Make sure that your email program does not cut off yourtext! The content should include your name, your company name, your email address, fax number, and any other contact details, such as 800 numbers. Lastly, always include a short personal message about your company.

It should be a subtle sell of your services or your products, and possibly your company's reliability and longevity.

Another specialized use of autoresponders is to create courses that you can then offer your site visitors for free. You must choose a topic in which you are an expert and that precisely targets your potential customers. Once you have carefully chosen your subject, divide it into a number of different sub-topics. Then offer your site visitor a free 10 or 15 day course, each day offering a different sub-topic. The first topic should always be a welcome message to your site visitor and an explanation about what is to follow. Your explanation should been ticing, getting the point across that you are offering free, quality information that your target audience willfind of great value.

With every lesson, include the number of the lesson, the topic title, information about your company and its services or products. At the end, include a few blurbs about the next lesson to entice the subscriber to continue on.

Make sure each topic is packed with essential and valuable information, and leaves the visitor lusting to know more. Otherwise, you may lose them in the very beginning.

Of course, you have to write up your course before you can offer it. Once you have done this, and gone over the material carefully, employing a professional writer or editor if necessary, you must transfer your text to your autoresponder.

There are a number of free autoresponders you can use.

Try http://www.getresponse.com, http://sendfree.com, http://iberbiz.emailaces.com/or http://freeautobot.com.

Or go on to Google and you will find a long list of free autoresponder companies. Then sign-up for your chosen autoresponder. Once you do, you will receive instructions as to how to set it up and transfer your text.

Autoresponders are an effective and powerful marketing tool, allowing you to make contact with thousands of potential customers. This is an invaluable asset considering how many potential customers you usually have contact with before you make an actual sale. Essentially, an autoresponser allows you to automate part of your marketing campaign.
