One of the great ironies about China for multinational firms is that they feel they have to be there, but the gatekeeper doesn't always let them in. This paradigm is especially evident in the financial services sector, where foreign firms control less than 2% of the market 18 years after China entered the World Trade Organization and promised to dismantle trade and investment barriers.

Singapore is an ascendant digital finance hub, in 2018 attracting $365 million in fintech investment. That investment was double the amount raised a year earlier. Despite its small size, the city-state is still the No. 5 fintech market in APAC by funds raised.

Japan is the world's No. 3 economy and known for its tech prowess, yet the Japanese people prefer cash over other forms of payment. Just one in five transactions in Japan are cashless. Some analysts say that Japan can learn from its giant neighbor China when it comes to cashless payments. In less than a decade, China has gone from cash reliant to nearly cash free. In 2017, nearly half of the world's digital payments were made in China.

It wasn't so long ago that China's tech firms were panned as second-rate copycats. The best example might be Baidu, the search giant that is often less effective than Google in Chinese-language searches.

Tencent's WeChat messaging app changed the equation, establishing a mobile-internet ecosystem that is the envy of its global competitors. WeChat has over 1 billion monthly users (mostly in mainland China) and is the No. 5 most used app globally. Its payment platform has expanded to 25 countries. Thanks in part to WeChat business Tencent had a strong third quarter in 2018. Revenue reached $11.7 billion, up 24% over a year earlier, while profits rose 20% year-on-year to $3.4 billion.

If your competitors are there, do you need to be there? Mastercard thinks so. Along with Visa and American Express (AmEx), it is trying to gain a foothold in China following Beijing's announcement in 2017 that U.S. credit-card companies could apply for licenses. In late 2018, Beijing approved the first such bank card transaction clearing license when it signed off on a joint venture between AmEx and Chinese fintech firm Lianlian.

Mobile payment adoption is accelerating in Thailand as the finance sector moves to digitize. Like its Asean peers, Thailand is keen to use digital finance to boost an underdeveloped banking sector. Without the entrenched incumbents of developed economies, Asean countries tend to view digital finance as a greater opportunity than threat. Even highly advanced Singapore has embraced fintech, with an eye towards becoming Southeast Asia's fintech hub.

In Japan, cash is still king. Indeed, the Japanese have a fondness for physical currency that has ebbed amongst their neighbors. Cash accounts for 80% of transactions in Japan, compared to 40% in China and 10% in South Korea.

Facebook is reportedly developing a cryptocurrency that will be backed by the U.S. dollar for the Indian remittances market. Known as a "stablecoin," the digital currency will allow users of Facebook's WhatsApp messaging app to transfer money. Stablecoins have many applications besides remittance, including peer-to-peer payments, the purchase of goods and services online, and trading of digital currency. Facebook's digital currency is at a nascent stage and won't be released for some time, according to a December Bloomberg report.

Years ago, traditional POS machines only provided basic processing that were more convenient than cash transactions, but provided little help when it came to sales analysis. Smart POS started gaining traction in 2014 and grew rapidly as merchants juggled many different payment channels. A smart POS can process QR code, bank card, Quick Pass, as well as analyze business data, maintain membership details and combine online–offline sales. In December, UnionPay and Alipay both launched new acquiring products.

Double 11, the biggest e-commerce shopping festival, had another amazing result in 2018. On November 11th 2018, total online sales in China reached RMB314.2 billion (USD45.2 billion) in one single day.
