List three advantages of RFID technology over barcode technology?
Best answer:
- RFID tags do not have to be visible to be detected/scanned. For instance a tagged item could be inside a box and yet still be scanned.
- RFID systems allow scanning from further distances than Barcode scanning.
- Several items can be scanned at the same time with RFID systems vs. the one at a time method that barcode scanning uses. For instance it should be possible at some point for you to roll up with your grocery cart and be given a total within a few seconds, instead of the cashier having to scan each item.
I can think of others but you only asked for three.
A LED Barcode Scanner works on a technology which is fairly different from that used in the laser scanners. In LED scanners, a series of tiny light sensors are arranged in a row. The light which is reflected from the barcode label is then trapped and measured by these sensors.
Though this technology is least popular but can be used in a wide range of applications. A LED Barcode Scanner is perhaps the most durable scanner which is due to the non-existence of moveable tiny machinery parts in it. The light plays the major role in such types of scanners. A LED Barcode Scanner is mostly found in warehouses, industrial units, etc. where the chances of accidental fall of the device are quite high. The sturdiness of this type of scanner makes it perfect for such working environments.
The functional technology is quite different between an LED scanner and a laser scanner, but while reading the characters of a barcode label, both are alike, as both are held static over the barcode so that they recognize the code.
A laser scanner needs to move back and forth across the barcode label so that the reflected light is trapped by the scanner, while a LED scanner needs not to be moved. The miniscule light sensors of a LED scanner pick up the ambient light emerging out of the barcode label.
A LED scanner is sometimes also referred to as a CCD scanner. CCD is the abbreviation for “charge-coupled device.” CCD, in fact, is the characteristic of a LED scanner that help the electrical charge to get converted into digital information.
The functioning methodology of a LED scanner is quite similar to that of a camera based, or a 2D imaging scanner. The major difference between these two types of scanners is that a LED scanner picks up an image of the barcode, while a camera based scanner takes a real two-dimensional image of the barcode label.
People use barcode scanners but often fail to recognize the difference between a LED scanner and a CCD scanner. The swiping machines in which people swipe their credit or debit cards contain a LED scanner that reads the magnetic strips of the cards and transfers the information encrypted in the card to the computer. A LED scanner is also used in the attendance recording machines in offices and also used in the locks on hotel doors for security purposes.
A LED scanner is comparatively more efficient than other laser scanners. A LED scanner can read even smaller labels with great comfort. Only disadvantage that one can complain of a LED scanner is that it normally comes with a lower scanning range. This type of a scanner can read a barcode label from a distance of less than three inches only.

Investors are trying their best to cut the cost of doing business and are spending money for new, but affordable technologies. An example is a barcode reader that comes in various types and uses.
A barcode scanner or reader is an apparatus utilized to trap and read information included in a barcode. This device may be a handheld or fixed stationary type.
There are three important components of a barcode reader. These are the scanner, the decoder and a cable. The decoder may either be seen externally or built-in to the device. The cable attaches the reader to a computer by way of various mechanisms such as keyboard or serial port ,or a wedge.
A wireless barcode scanner directs a beam of light across the bar code. The scanner transforms the light into electrical energy. The decoder converts the electrical energy into data of numbers and letters. These data is forwarded to a PC to be analyzed by a software.
There are several types of barcode readers and these are as follows.
Wireless barcode scanner. This one is highly essential when collection of data away from a computer is required. It is more popularly known as a mobile computer and data collector, and it serves as a versatile device for sophisticated capture of information.
It makes use of different operating systems such as Windows Mobile, Palm and Linux. Only a wireless barcode scanner can give you ease of mobility.
At times, you simply need to leave your computer to secure the data. Or, you’ll have to gather information far away from any computer and have the data transferred from the scanner to the computer. You may also need to be self-sufficient of a computer and prefer to work to a database on the network.
With this, the barcode scanner can offer a wireless network connection, and the operating system will be directing to the source of data to update it.
Slot scanner. This kind of reader is fixed. Its main function is to read bar codes on identification cards. It is useful in offices when logging in employees or time of check-in.
The Charge Coupled Device or CCD. It is a reader often used in retail stores. This one’s offer an improved scan and read-extent compared to the pen wand. This gun-typed interface device needed to be carried an inch from the bar code.
Pen wand. This pen-shaped or wand-shaped device offers economy and durability. Considered as the simplest barcode scanner, pen wand works by moving the tip of the pen across the bar code in a steady even motion. The tip of the pen must come in direct touch with all the bar codes.
Image scanner. It is also being referred to as a camera reader and normally has a lower price than laser reader. It has a built-in tiny video camera that captures images from the bar code. It then employs advanced digital processing system for decoding. Itcan scan a bar code from three to inches away. This is the latest of all the barcode readers.
Laser scanner. It is able to do 500 scans every second and can efficiently work even at 24 inches away from a bar code. Some models can even scan a bar code from up to 30 feet away. These are specialized long-range laser scanners.
Advantages of using a Barcode Reader
It can do faster scanning compared to a human data encoder. For instance, a pen wand can scan a bar code level of 12 characters at the same time when a data encoder can perform two key strokes. It can also provide businesses with accurate data entries. It prevents the entry of invalid information. It means that all information entered or inputted are highly reliable.
Another benefit is its lower system cost compared to other data entry systems. It demonstrated a payback period of 6 to 18 months. Investors of this type of scanning could easily regain their investment during that span of time.
Barcorama is a simple freeware application for Windows Mobile devices developed by the xda-developers user hypest. The application is still in development stage but it is possible to test the alpha-version of the programm. This software is based on the ZXing barcode reader software which is an open-source, multi-format 1D/2D barcode image processing library. This library includes all common barcodes like UPC-A, UPC-E , EAN-8 and EAN-13.

The use of barcoding and barcode scanners has transformed operational efficiencies of a phenomenal number of businesses both large and small. Simple yet effective, the barcode as an invention has made itself indispensable purely by the multi-faceted advantages that its offers to the user across the entire barcoding spectrum – from generating barcodes through customizable barcode generating software right up to sophisticated barcode scanners and barcode readers. Here we present to you the killer advantages of these marvelous devices.
Super Advantage 1: Speed and Accuracy – A really good data entry operator would be able to enter a 12 digit number (like product code for example) on his keypad in approximately 4-5 seconds, but the average would be more like 7 seconds. The same operation if performed with a barcode scanner would take just one flick of the wrist, less than a second. The speed difference is evident – the use of the barcodes is unmatched in its ability to plough through large volumes of these operations effortlessly. While a data entry operator might make keyboard errors when he types in data, the chances of a barcode reader giving wrong output is practically nonexistent tending almost to zero. For all practical purposes, accuracy is exact, every time the barcode reader makes its flowing motion over the barcode.
Super Advantage 2: Implementation Ease – You decide you want to start using barcodes for your products but are worried that you have never done it before? Fear not, for in 10-20 minutes of your time that scenario will get reversed. The use of barcode readers is almost childishly simple with no prerequisite for usage. Not only can anybody do it, but they can do it quickly as well for the learning curve of using barcodes is extremely steep and short.
Super Advantage 3: Bang for the buck – If you could capture information quickly and accurately, it could only mean a tighter supply chain and well-knit business processes based on this information. With superior information, you can take superior business decisions that increase shareholder value. Imagine what disastrous consequences incorrect information could have on your business! A vast collection of barcodes and barcode scanner usage data has revealed that the investment made in this technology pays back in as short a period as 6 to 10 months – way faster than most modern technologies that attempt to improve the way we conduct our business. Thus the barcode genre is one where the customer truly gets good value for money and high return on investment.
One can never get enough of the importance and advantages of barcodes and barcode scanners. It now only remains for you to start scouring the market for various barcoding solutions to unlock the immense savings and gains that are lying in wait for your business! Go ahead and barcode your business growth in to the future!
A barcode reader (barcode scanner), also called a price scanner or point-of-sale (POS) scanner, is a hand-held or stationary input device used to capture and read information contained in a bar code. A barcode reader consists of a scanner, a decoder (either built-in or external), and a cable used to connect the reader with a computer.
There are five basic kinds of barcode readers each with its own unique advantage. Those are Pen wands, Slot Scanners, Charge-Couple Device (CCD) Scanners, Image Scanners, and Laser Scanners.
· A Pen Wand is a simple barcode reader which is known for its durability and low cost; does not contain any moving parts. It has to remain in direct contact with the bar code at a certain angle.
· A Slot Scanner remains stationary and the item with the bar code on it is pulled by hand through the slot. Slot scanners are typically used to scan bar codes on identification cards.
· A CCD Scanner often used in retail sales has a better read-range than the pen wand. A disadvantage of the CCD scanner is that it cannot read a bar code that is wider than its input face.
· An Image Scanner, also called as Camera reader, uses a small video camera to capture the image of the bar code and then uses sophisticated digital image processing techniques to decode the bar code.
· A Laser Scanner, either hand-held or stationary, does not have to be close to the bar code in order to do its job and can easily read a bar code up to 24 inches away. A laser scanning may perform up to 500 scans per second to reduce the possibility of errors.
Advantages of Barcodes: -
Barcode scanning systems provide an array of benefits, including operational efficiency, better customer service, and improved visibility of key business information to management.
A bar code label of twelve characters can be wanded in approximately the time it takes a keyboard operator to make two keystrokes.
Accuracy:
For every 1,000 characters typed by a keyboard operator, there are an average of ten keying errors. For an Optical Character Reader (OCR), there is one error in every 10,000 reads. With wands, barcode systems approach one error in every 3,000,000 characters, and with laser technology, they approach one error in 70 million entries.
Data Integrity:
When all the products or item data is Barcode scanned, it is free of human errors when data is entered. Barcode scanners works as a designed user interface that prevent the input of invalid data.
Probable number of substitution errors per 3,400,000 characters
Data Entry Meth — Errors
Keyboard Entry — 10,000
OCR Scanning –300
Barcode scanning(Code 39) — 1
Ease of Implementation:
Operators of bar code scanners can learn to use the equipment effectively in less than 15 minutes. System costs are lower than other means of data entry because of the existence of interfacing hardware and software.
Cost Effectiveness:
Barcode systems have a demonstrated payback period of six to eighteen months, and they provide the highest level of reliability in a wide variety of data collection applications. Barcode systems create value not only by saving time, but also by preventing costly errors.
Information is the most valuable asset for any organization. Every organization should protect its operations data with reliable data management by ensuring data accuracy and availability. Barcode Scanners equipment helps firms in maintaining accurate supply chain and operations data management.
