How To Choose A Barcode Scanner?

Barcode scanners are light emitting devices that are used to read barcodes. Usually attached to a computer or laptop via PS2 or RS-232, the data collected is stored on a computer for processing or storage. It is now used in many different industries such as retail or production.

They have been on the market for many years now with new versions of barcode scanners available every year. The prices can vary from as low as $50.00 to as high as several thousand dollars. So how do you pick a good barcode scanner?

To answer that question, it is important you know there are 2 major classes of barcode scanners, image-based and laser-based. Image-based barcode scanners use a camera usually embedded in a barcode scanner. The camera will capture the images and then processed by complex image techniques to decode the barcodes. Laser-based barcode scanners uses mirrors and lenses to read the barcodes.

Laser barcode scanners are usually more expensive than image-based scanners. They have their own pros and cons. An image-based barcode scanner do not have internal movable parts therefore are more resistant to drops or knocks than laser barcode scanners. Also, image-based barcode scanners have a shorter scanning distance (4 to 10 inches) compared to laser barcode scanners. On the other hand, laser scanners are more prone to wear and tear due to their lenses. They not only have a longer scanning distance (up to 24 inches) but also are able to scan from a wider angle from the barcode.

Be aware that the scanning distance for both image-based and laser barcode scanners have already improved dramatically over the years and I wouldn’t be surprised if a barcode manufacturer claims an image-based scanner has a scanning distance of 24 inches.

Here are some questions you need to ask yourself before getting a barcode scanner. The size of scanner required? Type of environment the barcode scanner will be using (outdoors, shop, warehouse)? The scanning distance required? Are they to be used hands free or hand-held? Your budget?

So my suggestion is if you need a barcode scanner for long range scanning, get a laser barcode scanner. For short range scanning, use an image-based barcode scanner such as a CCD barcode scanner. The environment as I asked earlier also plays an important part. If the barcode scanner is being used outdoors or in rugged environments where it is expected to take a drop or knock or two, then it is best to get an image-based barcode scanner. If it were for example being used in a retail shop, then a laser barcode scanner would be the best choice.

There are such a wide variety of barcode scanners available that I just can’t explain completely in this article. If you are in doubt, consult the barcode manufacturers such as symbol or metrologic who have sales consultants who are able to do an analysis of the type of barcode scanner needed by your business.

An Introduction To Barcode Equipment

A complete barcode system will consist of software, scanners, a printer or labeler and labels for thermo transfer or thermo direct printing. Also of interest are mobile terminals for mobile data acquisition with a built-in scanner or reader, a display and a keyboard. A POS (point of sale) solution will require laser barcode scanners with high throughput and automatic triggering for hands-free barcode scanning.

Barcode Software

Barcodes are created with special software. While barcode software for Microsoft Windows is available, best suited for barcode creation are Apple Macintosh computers. Macs are preferable due to their strong position in the DTP, prepress and graphics market segment. A typical barcode software will support the common symbologies, calculate checksums automatically and will provide a variety of output options with support for the most common images formats (like PNG, TIFF or JPG) and also for Post Script or EPS.

A cheap alternative to dedicated barcode generators are so called barcode fonts. However, the quality a barcode created with such a font will usually not conform to the respective standards.

Depending on the application the use of dedicated, barcode enabled, label printing software may be advised. For example, such software can be used to print sequential barcodes (for serial numbers) or print logos or product images next to the actual barcode.

Barcode Scanner

Barcode Scanners, also known as barcode readers exist in various forms: The most common type are laser scanners. Here a moving laser beam scans the code which results in fast and error free reading. A cheap alternative to laser scanners are CCD scanners that feature a row of light emitting diodes and photo detectors. The earliest type of barcode reader where so called barcode wands, also known a magic wands. Here a single light emitting diode (LED) and a single photo detector are used to detect the typical black and white pattern of a barcode. While laser and CCD barcode scanners scan a barcode as a whole the barcode wand has to be swiped across the code to read it.

Barcode Printers

Barcode printers are used to print the barcode on self adhesive labels. Today most barcode label printers work in either thermo direct or thermo transfer mode. Using the thermo direct principle the print head applies heat to selected parts of the label which then turn dark. This is the same principle as is used with older fax machines. Thermo direct labels are sensitive to light and should not be used if they have to last longer than a few days or weeks. Typical applications are address labels which only have to last a few days.

With thermo transfer printers a heat sensitive ribbon (thermo transfer ribbon) sits between the print head and the label. As heat is applied to the ribbon, ink transfers (hence the name) from the ribbon to the label. Labels that were printed with thermo transfer are very durable. However, besides the actual label the transfer ribbon is another consumable which will increase the printing cost.

Comparing Auto Insurance Quotes Online

Auto insurance refers to the insurance which is used for insuring the automobiles against any kind of uncertain accidents that may cause damages to the vehicle. The main purpose that the insurance serves is to give protection against the losses incurred due to accidents. Auto insurance is a type of insurance that consumers must buy to protect the life span of their vehicles and also for any kind of damages that the vehicle may suffer in an accident. Auto insurance is used to insure many automobiles such as cars, trucks and any other kind of vehicles that may need it. Different kinds of coverage are available under these insurance schemes such as Third-Party Foreign Theft and Fully Comprehensive insurance, to suit the interest and the needs of the insured.

Before buying auto insurance, it is very important that the person requiring insurance analyses the companies that provide vehicle insurance quotes. Different companies offer different quotes for the insurance of the vehicle, so the consumer must look out for the best one, which suits his needs and which proves to be highly economical. Many companies also give different discount schemes to attract more and more consumers. The consumer can save a good deal of money while purchasing auto insurance by comparing the quotes of different companies and choosing the cheapest one which satisfies all needs.

Comparing the quotes of different companies on the internet for buying insurance provides a wider platform to the consumer, where they can compare quotes from several companies and choose one among them. The main thing about choosing a quote is that the quote need not necessarily be cheap but the company must be an established one which the customer can rely on should they have an accident.

The consumer should not only compare the quotes of different companies but also the company’s reputation and their way of service. While comparing, the consumer is more acquainted with the different kind of coverage that are available and can choose among them according to the needs. Buying insurance online is the most popular way of buying insurance because it is really fast and convenient, which suits to the busy life of people who have little time to phone around the various companies to relay the details of the insurance cover they are after over and over again. And the best part is that it is free of cost, i.e. no cost is involved in gathering the quotes online from different companies.

Auto insurances are needed because of the reckless accidents that happen on our roads day after day. These can only be reduced once the certainty of the accidents is reduced. The companies quote their prices for insuring depending upon various factors like the age of person to whom the vehicle belongs, the location where the car is bought and supposedly to be used and also many other factors like whether the driver already has points on their licence. The details regarding the car, like where it is being parked, whether or not it is kept in a garage (which is supposed to have less risk of being stolen) and also the mileage of the car are also deciding factors. If the car travels less than a specific limit of miles then such cars are likely to receive some kind of mileage discounts.

Saving Money With Online Auto Insurance Quotes

Shopping for online auto insurance quotes can be quite demanding, but knowing that they are a lot cheaper, faster, less complicated and extremely convenient, we all have to do it at one point of time or another. This compilation of tips may be able to help you avoid overpaying for your car insurance premiums, and save a few hundred dollars in the process.

1. Search for Auto Insurance Quotes Regularly: If you do not shop around for online auto insurance quotes, you can end up paying the same premium for years, which is really pointless because as vehicles age, they decrease in value. So, you should not pay the same premium on them as you would on newer vehicles. Get into the habit of conducting a quote search, perhaps, on a yearly basis, and the more often you do it, the better your chances of getting lower online auto insurance quotes.

2. Consider “liability only” Insurance for Older Vehicles: Before getting your online auto insurance quote, always take into account the value of your vehicle compared to the amount you’re paying for premiums when making decisions such as “liability only” insurance. For example, if the wholesale value of your car is $1000, you need not pay nearly that much per year because that is all you’ll receive from the insurance company in the event of an accident.

3. Take a Defensive Driving Course: Your online auto insurance quote is also affected when you take a simple 6 hour defensive driving course, which can save you up to 10% on your auto insurance premium. The local department of motor vehicles should have more information on this. Otherwise, there are also courses available through mail, video, or the internet.

4. Insure with the Same Agency: When you apply for online auto insurance quote, remember that most insurance companies will give you a discount for multiple auto insurance policies. So if you own more than one vehicle, you should insure each of them with the same insurance agency. If you also have life, home, fire, boat or any other type of insurance, use the same agency for your auto insurance.

5. Raise your Deductible: Higher deductibles result in lower insurance premiums, so set your deductible at the highest rate possible. At the same time, it’s also imperative that you do not neglect additional financial resources that can help cover the deductible in case of an accident.

6. Check your Credit Rating: Be aware that most insurance companies will check your current credit score as part of their calculation for your insurance premium, since like all other business setups, they want to be paid, and on time. So you need to maintain a healthy credit rating before you get your online auto insurance quote.

7. Let Them Know why you are at Lower Risk: Insurance companies mainly base their rates on one element – risk. Therefore, you need to have valid reasons why you are at lower risk when obtaining your online auto insurance quote, such as having a safe vehicle, a clean driving record, anti-theft devices etc.
