How does a QR code generator work?

It encodes your input into a matrix pattern following the QR standard, readable by any scanner app.

Can I customize a generated QR code's appearance?

Many generators allow color/logo customization as long as contrast and error correction are maintained.

A standard QR code with embedded data never expires; only dynamic redirecting QR codes could stop working.
