Pi Pay is the largest digital wallet in Cambodia's nascent fintech space, having processed 7.5 million transactions of $170 million as of March. The company has 250,000 users and 3,500 merchant partners.

Founded in mid-2017, Pi Pay is unique among Cambodia's fintechs for its strategic partnerships with traditional financial institutions and internet financiers alike. Among its key partners are Alipay, WeChat Pay and Korea's KB Kookmin Bank. The tie-ups with Alipay and WeChat Pay allow Pi Pay to tap the sizable Chinese tourist market in Cambodia. By 2020, Cambodia expects roughly 2 million Chinese visitors per year. Partnering with Kookmin Bank gives Pi Pay access to the 76,000 users of the banks' digital platform Liiv in Cambodia. Last year, Liiv processed overseas wire transfers of $17 million and extended $19 million in loans.

India's fintech giants Paytm and Ola are both entering the credit-card business, a move that should boost cashless transactions in an ascendant payments market estimated to reach $1 trillion by 2023. Digital wallet Paytm is cooperating with Citibank while ride-hailing juggernaut Ola is working with State Bank of India and Visa. Credit cards could offer Paytm a way to better compete with the U.S. tech giants who recently entered India's payments segment. For Ola, credit cards are a new way to generate revenue from its huge userbase. Visa and SBI hope to tap Ola's massive userbase to grow their own customer pool.

Ironically, both fintech giants are turning to a traditional financial platform to grow their businesses. Perhaps there is some truth after all to bromides about how financial incumbents and upstarts have more reasons to work together than compete with each other.

As a near developed country with high financial inclusion, Malaysia is an outlier in Southeast Asia. Like its rich neighbor Singapore, Malaysia's need for fintech is less pressing than poorer underbanked countries like Indonesia, the Philippines, Cambodia or Myanmar. Fintech platforms can facilitate smoother banking for Malaysians, but aren't viewed as a necessity in the country yet. After all, 92% of the population has a bank account and credit cards have a strong foothold.

Axiata Group's Boost digital wallet, established in early 2018, is one of the first Malaysian fintechs to have a demonstrable impact on the country's financial system. Boost's executives say that it is Malaysia's premier digital wallet, with 4 million registered users and 80,000 merchant touchpoints. From January-December 2018, Boost users' average monthly transactions grew fourteenfold, the company says.

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.

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.

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.

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.

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.

China's bank card market is large. Over 9 billion domestic payment cards will be in use by the end of 2018, a nearly 35% increase from the 6.7 billion in 2016. Even though the market is replete with card providers, the clearing business has been always dominated by the only one licensed clearing institution, China UnionPay (CUP), for both domestic and cross-border RMB transactions. That is, until now.

During the Internet Security Summit in Beijing on August 21st, Ant Financial announced the official upgrade for the security control of its digital payment platform – Alipay. The more secured process is achieved through what is called a 'Delayed Payment' (DP) function.
