I've seen this question in a few places. A QR code (Quick Response code) is like a square "bar code" that you can scan with your phone. What is this called in Esperanto and how do you pronounce it?
After reviewing the answers and discussions at the three links listed below, I have come the conclusion that "QR code" is sufficiently international to be directly translated into Esperanto.
The name of the letter Q is kuo, and I would pronounce it without the final -o on kuo, using an even stress on ku and ro (so that it doesn't sound like kuro-kodo, a running code).
You can just call it strekokodo but if you want to be specific:
- Dudimensia strekokodo
