Samsung Pay implements it slightly differently. Since, as a security feature, you cannot duplicate the chip on your credit/debit card, Samsung had to find a way to get around this problem. Samsung decided to go with virtual cards, which can be issued by banks supporting the technology. This basically creates a card with a different number for use virtually. Virtual cards are big hit in India. If you’ve ever used a service like Paytm Payments Bank, Airtel Payments Bank, ICICI pockets, or Zeta Super Card, you’ll know how convenient these cards are. You can generate card numbers on demand, change the PIN according to your whims, and even deactivate the card in case you gave it out at an insecure location. As of now, Samsung Pay has partnered with quite a few banks in India, including Axis Bank, Citi, HDFC, ICICI and Yes Bank. A few more banks including Standard Chartered, Kotak Mahindra and AMEX have been recently added along with wallet players including Mobikwik and Paytm. Samsung Pay now accepts UPI as well, making it a really good case of how a device can become a platform for payments.
