## Showing a QR Ph code

With a payment link (the default), Weav's page shows the code for you. If you ask for the raw string (`"next_action_format": "DIRECT"`), you render `next_action.qr_string` as a QR code yourself. QR Ph codes carry the QR Ph symbol in the center, laid out exactly like this. Bank and e-wallet apps expect it, so a code that's off may not scan:

(Figure: a sample QR Ph code. 29 × 29 modules of 8 px, a white quiet zone of 4 modules on every side, and the full-color QR Ph symbol in a white box at the center, 23.81% of the code's width.)

- Error correction level Q (M at minimum), black modules on white, whole pixels per module (no blurring), and a white quiet zone of at least 4 modules on every side.
- A white box in the exact center, 23.81% of the code's width (50 ÷ 210, measured without the quiet zone), with the full-color QR Ph symbol filling about 80% of the box. Don't recolor, invert, stretch or add effects to the symbol.
- Logo size = code width × 0.2381, rounded to a whole pixel; nudge it by 1 px if needed so (code width − logo size) is even, then offset it by half the difference on both axes. For example, a 210 px code gets a 50 px box at 80, 80.
- Scan-test on major e-wallet and banking apps, on iOS and Android, before you go live.
