¿Qué es un Código QR?
A QR (Quick Response) code is a type of two-dimensional barcode that stores information as a series of pixels in a square grid. Smartphones and QR scanners can read these codes quickly, typically to direct users to a website, display text, connect to Wi-Fi, or share contact information.
Why Use QR Codes?
- Bridge Physical & Digital: Easily link print materials (posters, flyers, packaging) to online content.
- Contactless Information Sharing: Share Wi-Fi details, contact info (vCard), or menus without physical contact.
- Marketing & Engagement: Direct users to landing pages, promotions, videos, or app downloads.
- Convenience: Save users from typing long URLs, complex passwords, or contact details.
- Versatility: Encode various types of data, from simple text to complex vCards.
QR Code Types Supported:
- URL: Link to any website.
- Text: Store plain text messages.
- Email: Pre-fill an email address, subject, and body.
- Phone: Initiate a phone call.
- SMS: Pre-fill a phone number and message.
- vCard: Share contact details (name, phone, email, company, etc.).
- Wi-Fi: Automatically connect to a Wi-Fi network (SSID, password, encryption).
Customization Options:
- Size: Generate QR codes from 200x200 to 1000x1000 pixels.
