It was expected that this feature would soon make its way to Samsung Pay and now it has. During its keynote at the Samsung Developer Conference 2016 today the company confirmed that you will now be able to withdraw cash from ATMs using Samsung Pay. The feature will come in handy when you forget or lose your debit card but need to withdraw some cash from an ATM.
Samsung has really improved its mobile payments service as it's also received support for membership cards which let users redeem points for rewards, and it works with gift cards as well. Users will also be able to use Samsung Pay to pay for transit and even for in-app purchases, paying for online shopping with Samsung Pay seamlessly. While the company confirmed that ATM withdrawals are now possible it didn't immediately confirm which banks are going to support withdrawals by Samsung Pay so we'll have to wait a bit for this crucial bit of information.
Update: Samsung has confirmed that initially users in South Korea will be able to withdraw cash from ATMs using Samsung Pay and only Woori Bank is supported. It hasn't announced these Samsung Pay features for other markets as yet, Samsung Pay is currently live in South Korea, United States, and China.
