The thing is something that works, and works well is hard to displace. Especially when it makes money. And when you are running a business and you have to choose:
- keep making money
- update system that is making money and hope it will work and it will stop making money
What really is the sane option here?
Also one other point the credit card companies are way better option for customer over say paypal.

- majewsky 6y agoYou'd have to limit yourself to a set of reasonably well-known words (and potentially weed out words that sound too alike). If we're very optimistic and assume the final set has 10,000 words, then one word has the same amount of entropy as 4 digits. Therefore four words and 16 digits are the same size of address space. You'd need at least five words. And you're quickly getting to the point where it's getting problematic to print these on the card in a font size that everyone can read (elderly citizens with bad eyesight included).
