QR Code - Review

• A matrix bar code access to  data optimization through digital gadgets - smartphone phones. 
• QR - An Abbreviation of Quick Response dealing with a 2D dimensions program.
• QR codes consist of high storage capacity, fast scanning and secure omnidirectional readability.
• QR format is consist of black square format that detects the data and transmitted it instantly.
• Build in Camera format enables the QR codes recognition read by smartphones.
• It becomes popular among people in terms of sending and receiving data from end to end transmission barcodes. 
• Sending or receiving payments via QR codes through apps is rapidly growing popularity among people.

Working Analysis and Barcode Configuration - 

• QR codes formatting is recognized as in the form of back molecules setting up with square pattern in the side bar of the while background with barcode encoder and decoder system.
• Barcode is programmed by Molecule Configuration - A configure system is ranging from number 1 - 40 versions where each configure is consist of different numbers and molecules these molecules can be arranged in white & black cordinate dots arrange in a systematic way of the Square pattern.
• A series of codewords and datawords enables symbol to read error connection data successfully by using the Mathematical method of Reed-solomon codes to read the Damage data.
• A series of four functional patterns of quit zone broder- All four sides of the QR codes has been surrounded by these patterns are -
• Finder Patterns, Separator patterns, Timing Patterns &  Aalignment Patterns.
• It helps in scanning and   identify the code orient for decodes.
• Whereas, on the other hand, all processing and accessibility are being optimized manually on the inside of the QR code processing system that is called as Encoding Region.
• Encoding Region of the QR Code deals with version info,  format info, data transmission error connection and codewords.

QR Code Setup and Optimization-

• In order to determine its networking and operating systems - After getting startup the process has been analysis the data through scanning by apps in which data are being assumption by encoding text into numeric, alphanumeric, bytes and kanji.
• Secondly, the data will begin to encode with textual form is done by mode indicator consist of 4 bits and each data slipt with 8 bits of long codewords.
• Thirdly the data codewords are being scanned by QR code after codewords are converted into text to encode them. 
• Fourthly the data codewords are formed into sets of blocks and arranged in matrix way. A series of codewords are able generated for data masking where the eight data masking pattern are required to determine to enable instant processing system.
• Finally at the end of the process formatting is done through the data pixels which generated by encoding of version pixels & error connection & enables the QR Code in matrix format.
