Debit card spending limits are daily caps set by your bank for security, typically ranging from a few thousand dollars, protecting against fraud but can be adjusted by contacting your bank for temporary or permanent increases for large purchases.

A payment gets declined by a bank due to issues like insufficient funds, incorrect card details (number, CVV, PIN, address), an expired or unactivated card, hitting daily spending/credit limits, or the bank flagging the transaction as potentially fraudulent due to unusual activity, location (like traveling), or merchant type. Technical glitches or a temporary hold placed by a merchant can also cause declines.
