After the due date, when can I use my credit card?

If my credit card is paid off. Should I wait until the due date refreshes, or may I begin utilizing it the day after the deadline? I recently used my credit card past due (before the website updated), and although my use increased, my FICO score decreased. The card was a chase.

You may attempt it, but it will be rejected. There will be no successful offline or online transaction linking the POS to the card issuer’s server. I don’t believe that any older paper-based gadgets that weren’t connected to the internet or a power source still exist. Furthermore, even if they did, the merchant would still need to verify the validity date, which would also be ineffective.
