Probably not, but you definitely should care about not issuing sequential credit card numbers. Probably not the best example, but I don't think it's hard to imagine some scenario in between the two that still presents a concern.
- seanhunter 4y agoYou can't just use sequential numbers for credit cards because they have a builtin checksum validation called "Luhn's algorithm" https://www.creditcardvalidator.org/articles/luhn-algorithm https://www.creditcardvalidator.org/articles/luhn-algorithm
- michaelmior 4y agoSure, that wasn't really my point though. My point was that there are some cases where sequential identifiers would cause security concerns and some cases where they would not.
