What is Point of Sale (POS)?

1 min read Updated

A point-of-sale (PoS) system for crypto is the hardware and software enabling merchants to accept cryptocurrency payments in physical retail locations — generating payment requests and confirming transactions in real-time.

WHY IT MATTERS

Crypto point-of-sale brings blockchain payments to physical retail. Merchants display a QR code or NFC tag, the customer scans with their wallet, confirms the payment, and the transaction settles in seconds (on L2 networks).

Solutions range from simple QR code generators to full merchant terminals (like traditional card terminals) that integrate with inventory and accounting systems.

El Salvador's Bitcoin adoption created the largest real-world test of crypto PoS. Lessons learned: Lightning Network enables fast payments, but UX, merchant education, and stable value (stablecoins) are critical success factors.

FREQUENTLY ASKED QUESTIONS

How fast are crypto PoS payments?
On Lightning or L2 networks: 1-3 seconds — comparable to card payments. On Bitcoin L1: 10+ minutes, impractical for retail. Network choice determines PoS viability.
Do merchants need special hardware?
A smartphone or tablet is sufficient. Some providers offer dedicated terminals. The requirement is: display a payment request (QR code) and confirm receipt (blockchain monitoring).
What about price volatility?
Stablecoin payments eliminate this concern entirely. Bitcoin payments can be instantly converted to fiat by the processor. Most merchant-facing solutions offer instant conversion.
