They can also read both 2D and 1D barcodes. 1D scanners can only read ID barcodes so are not as versatile. And unlike the 1D models 2D scanners can read barcodes from any angle.

The big advantage with 2D scanners is their reliability. They use advanced decoding algorithms which makes them faster as well as increasingly reliable.

The fact they produce vital information so swiftly and efficiently makes them a boon to modern business where inaccurate information can prove very costly.

2D scanners enable tasks to be undertaken which normally would involve several workers, so therefore saves on labour costs. Costly human and mechanical error is also removed as the business operates more efficiently thanks to the 2D barcode scanner.

These laser scanners are able to read barcodes quickly and accurately and from a distance of few feet. Wireless and Bluetooth wireless models can read a barcode from over a hundred feet. This demonstrates that laser barcode scanners are remaining so popular because they are versatile.

Another advantage of these laser scanners is that they are very easy to use. With an ability of reading up to 500 labels a second and the fact they can be used to read multiple barcodes without having to continuously press the trigger proves they are also incredibly efficient in handling.

Admittedly Laser scanners are more expensive than CCD barcode scanners. Their movable parts also make them less durable. But they remain easy and efficient to use and this has ensured they remain in common use.

USB barcode scanners come in different designs. The most basic is shaped like an old style pricing gun and operates when the trigger is pressed. But there other styles so the one to choose is down to personal taste. The plain fact is that whatever the design they contain checkers, decoders and barcode verifiers, so can do the job.

The USB scanners make an ideal cheaper alternative to wireless operated scanners. Wireless versions are ideal where you have to wander around to take scans and don’t want to be restricted by cable length. But the USB variety can be plugged into a laptop which is light enough to be carried.

These types of barcode scanner come in different kinds and sizes, some models weighing as little as 9oz or as much as 3lb. These scanners are connected to the computer, or in a supermarket or store to the till, by a cable or wirelessly

Cables can be up be up to five ft long, allowing plenty of movement for the scanner within a limited area. Some models can be connected up via the USB port. For those needing more freedom movement a wireless connection can see the scanner being used up to 160 ft from the computer.

Wireless scans are fitted with chargeable batteries. These can last up to 30 hours, or conduct 20,000 scans between recharges.

Lasers continue to be the most popular form of handheld scanner despite the subsequent development of LED. LED handhelds are more durable and are capable of multi-tasking. They can scan both horizontal and vertical barcodes. They are then able to translate the reflected light into ASCII data.

Handhelds can be connected up to a computer in one of two ways. They can either be linked with a cable or wirelessly. Of course, when the scanner is linked by cable the user is limited by length. A wireless connection gives much more freedom of movement.

One of the advantages of these scanners is their small size which enables them to be put in the pocket when not in use, lessening the chances of them being misplaced.

The best place to find a wide choice of barcode scanners, ironically for those operating online businesses, is online. A search on the internet frees you from geographical boundaries as you look for the best product available. Do a bit of research before deciding the best one to buy.

An ideal scanner to use with your computer is one which connects through the USB port. However, if you need to scan stock in a large storage room you may be best using one that is portable and connects to the computer wirelessly.

Whatever the type of scanner you looking for, there is every chance you will find the ideal one for your online business through an internet search.

Another decision to make is whether to choose a laser or LED scanner. LED is a more modern development but laser scanners remain the most popular choice.

Handheld, mobile or fixed scanners are also available. The choice should be based on the use of the barcode scanner. Handheld scanners are connected to a computer or terminal via wireless or cable.

Fixed scanners are usually found by conveyor belts or on the checkouts in supermarkets. Mobile scanners, which are linked to computer wirelessly, can be carried around to wherever they are needed and ideal for such jobs stocktaking, asset tracking, auditing, and scanning proof of deliveries.

Wireless and Bluetooth technology means that the barcode scanner does not have to be connected directly to the computer.

A wireless barcode scanner sends data the computer via a signal. This is similar to the Wi-Fi technology which many people use on their laptops and PCs. The scanner will also have a docking base where it can be charged.

Bluetooth is a more modern development of the wireless scanner.

There are scanners which can be linked with different computers via the USB port. This means that they can be used in various places, but still must be linked directly to a computer to operate.

The least expensive types of barcode scanner is the pen or wand scanner. These are held like a pen and the end is wiped across the barcode. This means they have to be wiped across at the right speed and angle, which means they are not as efficient as other types.

Fixed barcode scanners are usually seen at the checkouts in supermarkets. The item’s barcode is wiped out the scanner which records the item and its price. A development of the fixed version is the omnidirectional which can read the code even if isn’t in direct line of the scanner.

Laser barcode scanners continue to be the most common in use. They have been adapted to meet various scanning requirements.

The latest technological development is the 2D scanner which reads barcodes extremely quickly and accurately.

One of the most time consuming and arguably least productive activities for any business is the stock check. It also takes a lot of people to perform who would ordinarily be occupied in more useful activities. But a barcode scanner, linked to a computer and a database, can be used to perform the stock take in only a fraction of the time while using fewer staff.

These scanners also save a lot of time pricing goods on shelves, being much faster than the old fashioned pricing gun. They also speed up the movement of customers through the tills and checking out area. The goods are scanned by the cashier and the prices appear on the electronic till and totted up. This saves the cashier the task of having to input prices manually.
