How to stop Chrome from offering to save credit card information

If you use Chrome you’ll hopefully know there are settings that can control the information that it stores and syncs. I always turn off the offer to sync passwords – and also credit card details. But although you can stop syncing your credit card details, Chrome will still popup a message each time you enter a credit card number to ask if you want to save those details in the browser – and it doesn’t provide an option to turn this off.
However, the following undocumented settings might be able to turn off the credit card details save prompt.
  • Type chrome://flags into the address bar of the browser
  • Search on the resulting page for “Google Payments card saving checkbox”
  • Change the setting to Disabled
I am not sure that this works because I was still prompted to save when I put in a credit card number the other day.
