so far the social media platform that has been most successful in integrating payment systems into their platforms is wechat, i have been to china once and my friends there use wechat for almost all of our purchasing activities, such as going to restaurants, taking taxis, buying souvenirs, etc. and when i had this experience, i saw that the integration of payment systems on social media platforms was very helpful for users, especially for those who travel frequently and are too lazy to carry cash. they only need to scan and all payments can be made from their device.
indeed, issues regarding payment system integration may be adjusted to the regulations of the country concerned. because not all countries want to accept a social media platform to have their own payment system.
The reason why WeChat pay is successful while Applepay or Google pay is not that successful because one is forced by their government to be used by their citizens and others given to us and let us decide whether use it or not.
Most of the transaction moved to digital payments either it's done via banking or third party apps there is not much difference in it.
