A QR code, short for Quick Response code, is a type of barcode that can be read easily by a digital device like a smartphone camera. QR codes are commonly used to encode information such as website URLs, contact details, WiFi passwords, etc. When scanned by a smartphone, the QR code directs the phone to open the encoded information – like a web link or contact details. So can a QR code open a WhatsApp chat? Let’s find out.
How QR Codes Work
A QR code is a machine-readable optical label that can store different types of data. The QR code consists of black squares arranged in a square grid on a white background. The information encoded in these squares can be numeric, alphanumeric, or binary.
QR codes work by encoding data into pixel patterns. The black and white squares in a QR code represent the encoded data. These patterns are then picked up by a QR scanner or reader and interpreted into meaningful information. The data capacity of a QR code can range from a few dozen to thousands of characters.
To read a QR code, you need a smartphone, tablet or other devices installed with a QR scanner app and camera. The camera scans the QR code image and the QR app decodes the information using Reed–Solomon error correction algorithm. This algorithm can recover data even if the code is partially damaged. The decoded data is then displayed on the screen.
Common Uses of QR Codes
Some common uses of QR codes include:
- Product tracking and inventory management
- Website and social media promotion by encoding URLs
- Business card and contact information sharing
- Encoding ticket, coupon or voucher information
- Embedding text, emails, phone numbers, SMS
- WiFi login credentials sharing
- Payment processing
QR codes are popular because they provide a quick and convenient way to access digital information through a smartphone. They allow users to simply scan a code instead of typing out long URLs or contact details. QR code usage has grown exponentially with the widespread adoption of smartphones.
Can a QR Code Open a WhatsApp Chat?
Yes, QR codes can be used to open a WhatsApp chat or start a WhatsApp conversation. WhatsApp has a feature where users can create a QR code by going to Settings > QR code in the app. Scanning someone’s personal WhatsApp QR code using your camera will instantly open a chat with that person’s phone number.
This QR code contains encoded contact details that WhatsApp recognized. When you scan this code, it pre-populates the chat screen with the individual’s phone number so you can start messaging right away. The phone number encoded in the code must be registered to WhatsApp for this to work.
WhatsApp also provides a separate type of QR code for businesses. Scanning a WhatsApp Business QR code does not directly open a chat but instead prompts you to send a message to the business account ID encoded in the QR code.
