Offline QR Codes: Linking Without Connectivity

Offline QR codes are like digital time capsules – they encapsulate data that can be accessed without requiring an internet connection. Let's take a look at some common examples of offline QR codes:

Text QR Codes

These QR codes store plain text, allowing you to convey messages, notes, or even secrets. When scanned, they instantly display the text on the user's device screen, eliminating the need for an internet connection.

Wi-Fi QR Codes

Setting up a new device on a Wi-Fi network can be a hassle, especially when dealing with complex passwords. Wi-Fi QR codes simplify this process by encoding the network details. When scanned, the device automatically connects to the network, making it ideal for businesses, cafes, and homes.

vCard QR Codes

Business cards have gone digital with vCard QR codes. These codes store contact information, which, when scanned, can be added directly to the user's contacts without the need for manual input.

Online QR Codes: Gateway to Digital Content

Online QR codes, on the other hand, act as gateways to digital content hosted on the internet. They require an active internet connection to fulfill their purpose:

Link QR Codes

The most common type, link QR codes direct users to websites, articles, videos, or any online content. They're widely used for marketing campaigns, enabling quick access to promotional material.
Moreover, link QR codes offer an additional layer of convenience by enabling rapid access to users' social media profiles. By embedding the URL of a Facebook or Twitter profile, these QR codes facilitate seamless connections in the digital realm.

Email QR Codes

Share your email address effortlessly by using email QR codes. When scanned, they prompt the user's device to compose an email to the encoded address.

SMS QR Codes

Similar to email QR codes, SMS QR codes allow users to send text messages to a predefined number by scanning the code.

Crypto QR Codes

Cryptocurrency transactions have become streamlined with crypto QR codes. These codes contain wallet addresses, making it easy to send and receive digital currencies.
