Barcodes

Go onto google and click modular life ninjago codes. Hope this helps. Sorry that I haven't memorized them.

There are many very reliable locations to acquire a USB barcode scanner. Websites like Amazon and Newegg usually have some in stock. Also, a local Best Buy or Staples might have some available.

Basically, you can download them directly to their phone by scanning a QR code or by typing the shown Checkout link on their phone's browser, then land on a page where to find more information about the products you are about to download. That's really wonderful.

In the shows it is a scanner for when you see a creature, battlegear, attack, mugic or location scan it so you can have the thing for battling and there isn't one in real life

if you have an ipod you can download an app that will scan bar codes and it will tell you.

A barcode system is used specifically for an automatic data collection where hand recording items takes too much time or is even costly. Also this system has been proven useful for inventory control. So you can count how many items have been sold and not sold with efficiency.

From the the user's point of view - the bar-code reader is much simpler to use. You simply point the reader at the bar-code - and it scans the sequence of black & white lines, sending data to a computer - which tells the user what the product is.

With a keyboard, you would have to enter the long string of numbers printed under the bar-code - which not only takes more time - but could be entered wrongly.

Advantages:- Putting magnetic stripes on the cards are not expensive,so the cards are cheap.

Disadvantages:- Magnetic stripes may get damaged or the stripe reader could break down.
Sorry, I couln't think of lots but I got one: It contains up to only a certain amount of letters and words :)
magnetic card readers operate on magnetic strips, which are inherently susceptable to erasure, it doesn't happen often but it does happen, there are more advantages than disadvantages. another disadvantage is that mag card readers take a lot of wear and tear, the read heads must meet the card with direct tension and precision. the read heads are usually impregnated with diamond dust to prevent wear on the heads so they may read millions of swipes without significant wear that would widen the swipe gap, this diamond dust tends to wear the mag stripe out on the card quicker than the head wears away. mag cards have three areas for data to be stored and these areas vary in bits per inch that may be written to the the areas. more precision is required for higher rates of data bpi. rfid is fast replacing magstripe, it has a more robust security protocol, isn't affected by enviroment and is as compact as the magstripe.

A bar code reader is an input Device. Although they sometimes output a visible light, the purpose is to gather data from a printed code and input that data into your system (computer, Point of Sale, etc.)

What a bar code reader is requires an understanding of the amount of information contained in the Bar code itself. Simply the amount of information is huge. All a reader will do is use a LASER beam to collect or read the bar code and transfer the information into a computer.

Both terms apply to the same device. There isn't a difference.

anywhere inventory tracking is required. libraries, manufacturing plants, grocery stores, your smartphone, etc...

=Answer:==the first bar code was invented by Joseph Woodland and Bernard Silver. On October 7, 1952 they were granted a patent for it.=

One way is in the checkout process: when one or more items are scanned, cash is exchanged and one or more purchases made, the terminal running the cash register transmits that the item(s) purchased no longer exist instore, and once the central computer detects that the item(s) in stock are at a critical level, the central computer dispatches order(s) to providers to ship more of the product(s) back to where the same were originally purchased.

A portable barcode scanner cna be bought online from Amazon. It can also be bought from some of the companies that specialize in producing barcodes and scanners that work with them such as Spectrum Plastics.

A lot of cashiers use barcode scanners. They are also used increasingly in stock control applications, so warehouse workers use them. Delivery tracking is another application that uses bar coding for routing and recording of parcels.

Barcodes are also used by automated equipment as well as manually operated systems.

There are many different software programs available for making a bar code. When comparing professional bar code generating software, three stand out above the others. They are Bar Tender Professional, Nice Label Designer Pro, and Label Flow.

the advantages of a bar code reader is that you can scan things instead of entering the numbers but some software take webcams so i would just cheek if the program you are using accepts webcams as they are cheaper but if it don i would get a bar code reader.

In 1948, Bernard Silver was a graduate student at Drexel Institute of Technology in Philadelphia. A local food chain store owner had made an inquiry to the Drexel Institute asking about research into a method of automatically reading product information during checkout. Bernard Silver joined together with fellow graduate student Norman Joseph Woodland to work on a solution.

We can trace the idea of the modern bar code to around 1948, when a graduate student at the Drexel Institute in Philadelphia heard a conversation between one of the faculty and an executive of a food store chain. The executive was trying to convince the faculty member to have the school develop a system to quickly and accurately capture product data at the check-out counter. The student, Bernie Silver related the conversation to Norman "Joe" Woodland, a teacher at the institute. The problem intrigued Woodland, and for the next 2 years he would experiment with a variety of data collection techniques to find the one that worked.

Woodland "invented" the first barcode, basically by using Morse code - a series of dots and dashes used in telegraph and radio communications. Woodland wrote out the dots and dash representation of the product number and extended the lines of each vertically creating the first linear barcode. To read the barcode, Woodland adapted the DeForest movie sound system from 20 years earlier that used a sensitive tube to detect the projector light shining through the side of the film. In the movie industry, the light detected would be converted into sound. In Woodland and Silver's adaptation, the reflected light would be converted to numbers.

Barcode scanner, the laser in the barcode scanner is connected to a digital database, so when scanned it matches an item on the database that tells the person buying what it is and what the cost is, at the same time another machine is adding up all the items that have been scanned by the barcode scanner to create a grand total.
