What does the QR code in WhatsApp do - in detail?
The QR code feature in WhatsApp is a convenient and secure way to add new contacts or connect with others without the need for manual input of phone numbers. Here's how it works:
When you tap on the "QR Code" option within your WhatsApp settings, you will see a unique QR code generated specifically for your account. This QR code contains an encrypted version of your phone number and other necessary information to establish a secure connection with another user.
To add someone using their QR code, simply scan the QR code presented by the other person. WhatsApp will read the encoded data within the QR code, verify it, and then initiate a new chat session between your accounts. This process is seamless and eliminates the need for manually typing out phone numbers or searching through contacts.
The use of QR codes in WhatsApp also enhances privacy and security. Since the QR code does not reveal the actual phone number, users can share their contact information more discreetly. Additionally, scanning a QR code is faster and reduces the risk of entering incorrect numbers, ensuring a smoother user experience.
In summary, the QR code feature in WhatsApp streamlines the process of adding new contacts, improves privacy by not exposing phone numbers directly, and ensures a quick and secure connection between users.
