Samsung Pay is rolling out an international expansion plan today, revealing that the mobile payments service is now accepted in Spain, Singapore, and Australia.
Samsung Pay, which competes with rival services Apple Pay and Google’s Android Pay, lets people create a digital wallet on their Samsung smartphones by entering their credit card information. After that, they can pay for what they purchase by merely tapping their phones on a point of sale device that uses wireless technology.

What makes Samsung Pay different from Apple Pay and Android Pay is that merchants can accept payments using their existing credit card terminals. They do not need near-field communications (NFC) technology, another frictionless piece of technology, required by Apple (aapl) and Google (googl) to operate. Samsung Pay’s technology sends a small magnetic signal from a smartphone to a credit card reader, which is similar to the signal that’s produced when a credit card is swiped.
In addition to the three new countries, Samsung Pay is also available in China, South Korea, and the United States. Samsung said that it plans to expand to Brazil, Canada, and the United Kingdom this year. Apple Pay is currently available in China, the U.S., the UK, Canada, and Australia. Android Pay is currently only available in the U.S. and the U.K.
