Want to know more about "Bar Code". Types, Use, Each digit's representation, can we read without scanner?

There are different bar code standards, some of them are:\n\nEAN/UPC (ISO/IEC 15420)\nCode 128 (ISO/IEC 15417)\nCode 39 (ISO/IEC 16388)\nInterleaved 2-of-5 (ISO/IEC 16390)\nPDF417 (ISO/IEC 15438)\nMaxicode (ISO/IEC 16023)\nData Matrix (ISO/IEC 16022)\nQR Code (ISO/IEC 18004)\n\nThe most common is EAN/UPC.  Information on decoding it can be found here:\nhttp://electronics.howstuffworks.com/upc4.htm\n\nI hope this info helps, as instructions on each type would be exteremely exhausting to type out.

u only gotta selecta character,\nIt`s in typed version\nThose r actually computer codes,\nSo, that the computer may transform it in it`s actual character.

I would look into the system used by EZpass on highways and certain medications.RFID tags. They are usually from two to four square inches in size, and contain a silicon chip that holds a unique string of numbers identifying the item to which it is attached. A separate RFID "reader" receives the information contained in the tag through the tag's antenna. Unlike a bar code, the signal does not have to be read directly by a scanner; RFID signals need only to be in the vicinity of an RFID reader.

You ae confusing yourself!!! 0 - 255 is the range of ASCII characters. For eg. 65 stands for A and 97 stands for a and 1 stands for ☺. So you try 256 it will again display ☺ because there are only 255 characters. To know the value of an ASCII character press Alt + the req no. For eg Alt + 129 yeilds to ü. Go ahead try it yourself in any text editor. So a character variable can store only characters (ie. 0 - 255) NOTE:- Even all numbers are characters. Eg. Alt + 49 yeilds to 1 which is considered as a character. You know what I mean??? Don't you???

The answer to this question is WAY too long to take care of on the Internet so I'll just do some basics.  Keep in mind, though, that to truly be able to read binary code, you are going to have to do some studying.\n\nFirst, binary works off of only two "digits" being 0 and 1. In base-10 which we are used to working with, we have digits 0,1,2,3,4,5,6,7,8,9,0.  So to count something in binary, with less digit characters, we need longer strings of character. As with base-10, our smallest values are on the right and each column moving left-ward is worth more.  From the right, the binary columns are worth 1,2,4,8,16,32,64 are so forth. If you have a 1 present in the corresponding value column, you tally the value for that column. For example, to count to 40 in binary you have 01010000.  You don't really need that first zero for just binary but for computers you do, because we always deal with packages of 8 bits of information, or one byte.\n\nPractice a bit making common numbers with those value columns and once you can get the feel for it, you would need to translate that to letters. This is a separate issue and I can't give you an answer because different sets of characters use different values--- for example, US English uses one set of characters and French uses another because French language uses different character sets (such as accents, schwa, etc) that are not present in US English. Korean uses another character set, so does Hebrew, Spanish, etc... so once you master the basic making of numbers in binary, ask again regarding your chosen character set.

A good way to do that kind of thing is to click start - run and type in charmap and click ok. It lets you view and paste any symbol possible.

I think that you have lost a bar code font character... but not sure, never used that.

No program can turn a computer into a scanner. A scanner requires hardware. You DO have to have something that actually "SCANS" don't you?

There is no ascii code for those keys.  They have keyboard scan codes that change the states of how to interpret others keys.

Each digit is coded by two black and two white stripes. The stripes have widths of from 1 to 4 units, and the total width for each digit is always seven units.\n\nThis code is not quite all there is to it, however. Some digits of the barcode are reversed, so that they read right to left. Part of the code has black and white inverted, so black stripes are white and vice versa. This helps cut down errors and allows a computer to work out if the code was read from the wrong end when it was scanned.

you mean the key gen, a simple utility which makes your codes get's poped up without typing. think it this way. suppose the code for a software id a5. now if you press a5 the software will know that it is right. it means that it was inbuilt. so, if you software has the code in itself, a keygen can find it out. why now.

Bar-code values were created to help in billing and tracking of  goods. The bars are nothing but numbers represented pictorially. Bars of different thickness represent different numbers. A common standard is UPC bar-code that specifies the width of each number. One part of the bar-code represents the manufacturer and the other part is specific to the product. When a bar-code label is scanned, the barcode scanner scans the width of the bars and the software converts it to the information corresponding to the particular product like price, etc.

they don't translate anything. Once you press the key board it's already digital information. The fact that it as a letter sticker on it it's only for your understanding. It could very well have the real digital information sticker (for example 1001010 for the letter "a"), but it would be very unpractical for the common user.

you can get a scanner (dont think there expensive)

there are bar code fonts:\n\n\nhttp://cgm.cs.mcgill.ca/~luc/barcode.html

it's the numbers that represent every charater that can be inputted on a computer.  you can see the list here\n\nhttp://www.lookuptables.com/

Typically only the bar code is what you need for the UPC.\nIf in dobut however, include the extra six digit piece.\n\nEnjoy your rebate
