Human: Is it safe to use my debit card for online purchases? Assistant: 
It depends on the security measures of the website or store you are using. You should always check with your bank before making an online purchase, as they may have specific rules regarding the use of your debit card online. Additionally, make sure that you only enter your debit card number and PIN when prompted by the website or store, and be sure to look out for any signs of suspicious activity such as a sudden increase in spending.
