What is the QR code capacity limit?

Depends on version and error correction: numeric payloads hold more than UTF-8 text with CJK characters. Too much data breaks scannability.

Will an embedded logo break scanning?

A modest center logo often works with higher error correction; oversized or low-contrast logos can make codes unreadable.

Keep strong contrast between dark modules and a light quiet zone. Low-contrast or inverted colors often fail on phone cameras.
