What is a QR Code?
QR (Quick Response) codes are two-dimensional barcodes that store data in a pattern of black and white squares. Invented by Denso Wave in 1994, they can encode URLs, text, contact info, WiFi credentials, and more — scan them with any smartphone camera.
Common Use Cases
Sharing a website URL — put a QR code on a business card, flyer, or poster so people can open the link instantly.
WiFi network sharing — encode the SSID, password, and encryption type so guests can connect by scanning.
vCard contact exchange — embed your name, phone, email, and organization into a scannable code.
