## How to choose
- Does it process payments using a card reader and encrypt data? → 8471.90
- Does it include a touchscreen, processor, RAM, and storage as a full system? → 8471.41
- Is it only for card payment processing without computing or display? → 8470.50
## Overlaps & pitfalls
- A device with touchscreen, camera, and encryption (e.g., mobile POS) could fit both 8471.41 and 8471.90.
- If the product is a full system with display and processing, but also includes secure payment features, prioritize **8471.41** unless the camera or encryption is the defining feature.
- The term “POS terminal” appears in all, so use function and core technology to distinguish—**do not assume size or form factor determines classification**
