BARCODE

Barcode

dosto ap logo ne barcode ke bare me suna hi hoga ki kaisa hota hai ....
jab bhi hum koi product kharidte hai ,,, to us product ke packet me hum ko barcode dekhne ko milta hai ...


barcode ko barcode scanner se scan kiya jata hai ....taki us product ki identity jan sake.
 (identity = product ki price and name and uske bare me information )

for example .:  jab hum kisi mall se sopping karte hai to hum jo saman (product ) lete hai and lene ke bad hum counter per jate hai to waha pas jo counter man hota hai uske pas ak barcode scanner hota hai jisse ve person humare duwara liya gaya product ko scan karta hai means product per ak barcode hota hai us bar code ko barcode scanner se  kiya jata hai .....


jaise hum image 2 per dekh sakte hai ...

scan karte time scanner se ak Red bim nikalta hai jaise hum image 2 per dekh rahe hai ...

HOW TO WORK BARCODE


TO CHALIYE HUM AB YE SANTE HAI KI YE BAR CODE KAISE KAM KARTA HAI
Jab kisi product ko bar code scanner se scan kiya jata hai to scanner se ak Red bin bikalta hai ...
jo pure bar code me jitne bhi line , column hai usko scan karta hai...

pure barcode me 95 columns  hote hai .

pure 95 columns ko complete scan karta hai .
jab tak complete scan nai hoga tab tak scan karte rahna hai ... uske bad humare computer system me product identify hota hai ..  kyoki humara barcode scanner humare computer system se connect rahta hai...

jab hum scan karte hai tab RED line niklta hai jo humare barcode ke BLACK LINE (columns) se connect hota hai ya  milta hai . and jab ye dono red and black aapas me connect hota hai tab binary code me convert hota hai kyoki humara computer system binary  code ko samjhta hai ..

uske bad hume result show hota hai.

barcode per black line ke bich me ak  white gap   hota hai jaise hum image per dekh  sakte hai uper .

humara computer system black line ko 1 and white gap ko 0 man sakte hai .
kyoki computer system 0 1 ki language ko samjhta hai.


and scanner columns ko LEFT se RIGHT side scan karta hai .
red light and black aapas me connect ho raha h... jab red and black connect hota hai tab 0 bante hai and white se connect hota hai tab 1 mante hai .... complete scan hone ke bad result milta hai .



IS TYPE SE BAR CODE WORK KARTA HAI...


I THINK AP JAN GAYE HONE KI YE BARCODE HOTA KYA HAI AND WORK KAISE KARTA HAI ....

BUT FIR V YADI KUCH V DOUBT HO YA AP HUME KUCH INFORMATION DENA CHAHTE HAI TO COMMENT KAR SAKTE HAI ......AND SHARE JARUR KARE ....



THANKU
