It means Their computers decide when it's time to Raise your rates.Interesting - I'll have to try that for some things. Reminds me of the before-times, when you could call your credit card company and ask them to lower your interest rate on an annual basis. They apparently don't do that anymore and (multiple card companies) have informed me that interest rate adjustments are all "automatic" now, whatever that means.
They don't lower them anymore.
