It is not safe. Copies of ID cards are now at risk, so try not to lend the original ID card. Applying for a credit card requires your signature

Applying for a credit card requires your signature, but what if he signed it and submitted the form? The bank may not necessarily check whether it was signed by him, especially Many card applications are outsourced, as long as the materials are sufficient. Check the ID card information

Maybe he found someone who looks a lot like you to open a bank card? Even if it's not a credit card, it's still risky for you if he uses the card to do anything illegal. Another example is that he used your ID card to apply for a number at China Mobile or Telecom. State the purpose on the copy

It is best to write "Only for XXX" on the copy. Not to mention the risk of the original, but this is a small probability event, so worry too much It seems a bit unfounded to worry about it. Besides, the loan period is not long. I just need to be careful about ID cards in the future.
