A business can select what payment methods is wishes to use in its business and available for use by its customers. Generally more popular methods are used.
It is worth noting that the more payment systems a business uses, the higher the cost to the business…and ultimately what the customer pays. This is especially through costs being factored into the products/services or as a surcharge.
With more and more payment options becoming available (some through what is called digital disruption), the more variety exists and the more likely one’s preferred payment system won’t be offered by all businesses. This becomes ‘painful’ for the customer as they have to adopt multiple payment systems to cater for all their transactions or change providers to ones which use those one wishes only to use (which may mean limiting one’s ability to get the best deal).
There is good transparency. Payment options are usual available online and in terms and conditions/product disclosure statements. If one has limited payment options, some homework may need to be done before making purchase decisions.
This has been more or less covered here…
