<prompt> Human: Hello,Id like to know that if I pay via my debit card online, what information can the merchant access? Can they see, for example, my date of birth or home address linked to the card?Thanks in advance  <response>: No, but you open yourself up to a lot of risk if your debit card gets stolen due to a breach in the merchants system. I never use my debit card online. I never really use my debit card except at the ATM on occasion.
