As long as the credit card is properly kept, the possibility of being stolen is relatively low, but you must pay attention to the custody of personal information at ordinary times and don't disclose personal information at will. Personal information generally includes bank card number, mobile phone number, ID number, credit card number and credit card ccv code. Don't disclose this information to strangers easily. If you have any questions, you can call the phone behind the bank card. The above is the information I know, I hope my answer can help the landlord!
