It all comes down to the liberal banking regulations. Hong Kong is technically known as a "special admistrative region" of China built and administered like a corporate banking entity (down to the regional board of directors). Even after the British controlled territory was handed back to communist Beijing in 1997, the progressive democratic environment has only grown each year. From the independent rule of law to the currency with Queen Elizabeth still on it, Hong Kong SAR is still governed liked a monarch driven western society but with a lot of banking liberties due to its geopolitical dynamics.

Simply put, the banks have the freedom and resources to define much of their own infrastructure on the HK side so crypto debit cards are really no different than other existing smart-solutions used as mediums of exchange. In this regard, the USA is still approx. 5-7 years behind much of the civilized world when it comes to secure post/prepaid card systems. Blame it on the bureaucracy that defines our banking system or the general public demanding privacy at all levels in the face of a post 9/11 government who demands access to at least some of that privacy; it is what it is for the time being.
