You have arrived at the web home of Noah Brier. This is mostly an archive of over a decade of blogging and other writing. You can read more about me or get in touch. If you want more recent writing of mine, most of that is at my BrXnd marketing x AI newsletter and Why Is This Interesting?, a daily email for the intellectually omnivorous.
India has stringent rules on recurring payments using credit cards: For a “card not present” transaction, as in most online or in-app payments, the RBI requires a mandatory two-step authentication system, with a verification code that is sent to a customer via text message or email. The customer then enters the code to finish the transaction.I bring this up mostly because these sort of country-specific regulations never really occur to us as we imagine how businesses will scale. It's not to say Uber won't get over this (they're already working with a payment provider to get around the issue), but it does present interesting realities to global scaling that aren't often discussed.
