QR Codes 101: What They Are and How to Use Them for Your Business

A QR code is just a square barcode that stores a small amount of data — usually a link, some text, or WiFi details — that a phone camera can scan instantly instead of someone typing a URL by hand. Here's where they're genuinely useful:

1. Restaurant menus — print one QR code on the table instead of a physical menu that needs replacing.
2. Business cards — link straight to your portfolio, LinkedIn, or contact details.
3. Event flyers/posters — send people straight to a registration page.
4. WiFi sharing — encode your WiFi name + password so guests connect with one scan, no typing.
5. Product packaging — link to a user manual, warranty registration, or how-to video.

A few practical tips: keep the encoded link short (long URLs make a denser, harder-to-scan code), test it with your own phone before printing anything, and leave a small quiet margin of white space around the code so cameras can find it.
