It can process:
- EMV chip cards
- Magnetic stripe cards
- Contactless payments (NFC) like Apple Pay or Google Pay
- Mobile wallets and QR codes (on smart terminals)
Most machines connect to the internet via Wi-Fi, Ethernet, or cellular networks to authorize and settle transactions in real-time.
How Do Credit Card Machines Work?
- Customers insert, tap, or swipe their card.
- The machine sends payment information to the processor.
