Why do some online stores not ask for the 3-digit code on the back of my credit card?
Given that the laws on consumer liability for unauthorized transactions mean no cost in most cases, the CVV is there to protect the merchant.  Typically a merchant will receive a lower cost from their bank to process the transaction with the CVV code versus without. As far as the Netflix case goes, (or any other recurring billing for that matter) they wouldn't care as much about it because Visa/MC/Amex regulations prohibit storage of the CVV.  So if they collect it then it's only used for the first transaction and renewals just use the rest of the card info (name, expiration date, address). Does the presence of CVV indicate the merchant has better security?  Maybe, maybe not.  It probably means they care about their costs and want to pay the bank as little as possible to process the transaction.
