## Common ground
Both options describe physical devices designed to securely store and manage cryptocurrency private keys offline.
## Options at a glance
**8471.80 – USB-connected cold wallet**
- **Defining trait:** Requires a physical connection (micro-USB) to a computer or mobile device for transaction signing.
- **Typical examples:** Ledger Nano S, Trezor One (older models).
- **Best fit when:** You need a simple, hardware-based wallet that connects via USB and signs transactions on a trusted host device.
**8543.70 – Touchscreen digital vault wallet**
- **Defining trait:** Features an integrated touchscreen interface and offline key generation, with direct app integration (e.g., LIQUID).
- **Typical examples:** Ledger Live-compatible wallets with built-in screens, advanced cold wallets like Ledger Nano X.
- **Best fit when:** You want a self-contained device with on-screen verification, app connectivity, and enhanced user interaction without relying solely on USB.

## Overlaps & pitfalls
Both are cold wallets with offline key storage, so they overlap in core security function. The main difference is user interaction: one uses an external device (USB-only), the other has direct on-device control. If a product has both USB and touchscreen, prioritize **8543.70** if the touchscreen is central to its operation. Otherwise, use context (e.g., app integration) to decide
