Hi Friends, Aaj mai apko is post me Bar code aur QR code ke bare me bataunga. Barcode aur QR code apne bahut bar dekhe hoga aur isme Bar code to sabse common hai. Barcode me bahut si black aur white line bani rahti hai ek sath. Barcode ko apne dekha hoga kisi bhi product ke upper jaise Books, Soap, Oil etc. Jab bhi kisi bhi shop par jate hai to wha jo billing hoti hai product ki wo Barcode ko Scan karke karte hai.Jaise hi Barcode ko scan karte hai us product ka price apke Bill me automatically add ho jata hai.
QR code ek squre shape me bahut se dot-dot aur ajibo garib type ka symbol bna hota. QR code basically use hota hao ticket ke upper Online website par aur Visiting card ke upper bna hota hai. QR code use basically information share karne ke liye hota hai. Iska pura nam hota hai Quick Response Code. Friends mai aaj apko ye bataunga ki ye dono kam akise karte hai aur inse apko fyada kaise milta hai.
Barcode:
Barcode Numerical form me Information Store kar leta hai, Yah bahut hi choti information hoti hai , Jise aap Barcode Scanner ki help se Read kar sakte hai. Mai aap ko ek example se samjhata hu.
Meaning of Black and White Line in Barcode:
Aisa hota hai ki agar hum number ki baat kar rhe hai, to yha par 0 se laker 9 tak koi bhi number ho sakta hai aur Hamne hare k number ke liye 7 Line choose kiya hai.
Example: Inventory Management ,Agar aap ke pass ek store hai aur store me 20 tarah ke items hai aur hare ek product ke upper Barcode hai.
To apke pass system pta hai ki kaun sa item ka kitna Stock hai. Ab aise me agar apka koi product bikta hai to Inventory me wo product ek kam ho jayega aur apke bill me add ho jayega. Aise me aap kabhi bhi pta lga sakte hai ki kaun sa product bika hai aur wo stock me kitna hai.
Barcode Reader:
Barcode me har number ka line kaisa rahega aur kitna ptla mota rahega wo pahle se hi defined hota hai, Aise me jab Laser us line par padega aur White line se reflect hoker receiver ke pass information send karega to receiver ek 0 aur 1 ka sequence banayega aur use 7 (1000111) ke segment me divide karke pta lagate hai ki kaun sa number hai.
Barcode Disadvontage:
Friends agar bar code kahi se cut jaye to isme Error correction nahi hota hai aur isme bahut choti information store hoti hai, to is sab problem ko dur karne ke liye aaya QR Code.
QR Code (Quick Response Code):
QR Code me jayada information store hota hai aur isme error correction bhi ho sakta hai.Jaise agar apka QR code thoda cut bhi jaye to aap usme se information recover kar sakte hai.
QR code Alignment block, Error Correction block, Time Line:
Agar QR code ke ander jayda information store hota hai to besak iska design bhi bahut complex hoga.QR code 3 alignment block bane hote hai jo 3 square shape me rahte hai aur Timing line hota hai, Error correction block bhi hota hai. Alignment block, time line aur error correction apko hare k QR code me dekhane ko milega.
QR Code Data Storage:
Data ko store karne ke liye QR code me 2*2 ke 8 block bane hote hai. In block ko complete pattern me move karte-karte code me conevert kar lete hai.
QR code Scanners:
QR code me jitney bhi 2*4 block black spot hote hai hum inhe count karte hai, jaise ki agar 1 par black hai,4 par black hai to hum 1 aur 4 ko add kar leta hai jo hoga 5. Ab hum ASCII number me hum 5 ka matlab dekhate hai.
App kis bhi QR code ka information paa sakte hai kisi bhi QR code reader se ya fir apne smartphone se bhi.

Karamvir ji aap Paytm Account banaye aur apna Mobile Number Register kare. Uske bad aap apne Mobile Number ka Bar code Generate kare. Aur Payment ke Liye Bus Logo ko apke number ka bar code Scan karna hoga.
