QR Code Ki History

QR Code Japan mein develop hua tha. Iska pehla upayog car parts tracking ke liye hua tha. Uske baad, ye technology widely use hone lagi, aur aaj kal aap ise har jagah dekh sakte hain – from product packaging to advertisements.

Ek QR code ke structure mein kuch important parts hote hain:

  1. Finder Patterns: Ye patterns code ko scan karne ke liye use hote hain. Inka shape hamesha ek specific tarah ka hota hai.
  2. Alignment Patterns: Ye patterns code ko accurately scan karne mein madad karte hain. Inka arrangement center mein hota hai.
  3. Timing Patterns: Ye patterns code ke horizontal aur vertical alignment ko define karte hain.
  4. Data Region: Isme actual information encoded hoti hai, jaise ki URLs, text, contact information, ya kuch aur.
  5. Quiet Zone: Ye ek khali space hota hai jo code ke chaaron taraf hota hai, aur iska use interference ko kam karne ke liye hota hai.

Security Considerations

QR codes ka use karte waqt, security ko bhi dhyan mein rakha jana chahiye. Kuch tips security ko enhance karne ke liye:

  1. Only Scan Trusted Codes: QR codes ko scan karne se pehle, verify kare ki code trusted source se aaya hai.
  2. Avoid Scanning Unknown Codes: Unknown sources se aane wale QR codes ko scan na kare, khaaskar agar aapko code receive hua hai email ya message ke through.
  3. Keep Software Updated: Apne QR code scanner apps aur devices ke software ko updated rakhe taaki vulnerabilities ko patch kiya ja sake.
