In our life, in fact, many things can be used by others, such as our mobile phones, such as credit cards. However, sometimes we don't let others use them, but people use them through certain means. So how can we prove that credit cards are used by others? Next, Xiaobian will give you a detailed introduction. How to prove that credit cards are used by others can be considered from the following aspects: 1. Credit cards are generally consumed by password+signature. If the credit card consumption is not signed by myself, handwriting identification can be carried out; 2. When others use my credit card for consumption, they are not together in time and space, and I can request the judicial organ to obtain the video of others' consumption; 3. If the cardholder lends the credit card to others, the cardholder can fix the evidence of others borrowing the credit card by telephone, SMS, WeChat, QQ, etc. 4. Find an insider to testify. Who should be responsible for the stolen credit card? A credit card can only be signed, or a password can be set for it. However, in practice, the legal liability of a credit card with a password is different from that of a credit card with a signature only. The details are as follows: password card: the user is responsible. At present, the credit card articles of almost all banks stipulate that "all transactions made with passwords are regarded as the cardholder's own actions". Although this is suspected of overlord clause, in the court's determination, password is often considered as an important means to confirm the identity of cardholders and plays an important role in credit card consumption. This means that if the cardholder's password is also obtained by the other party when the credit card is stolen and robbed, he will bear the main responsibility for the stolen brush, and the responsibility of the acquirer is relatively reduced or even unnecessary. Signature card: Merchants pay the bill. Generally speaking, under the premise that the credit card has no password, the identity of the cardholder is mainly checked by the merchants. In the case of obvious differences in signatures, the merchants will undoubtedly bear the main responsibility for the success of the stolen brush. However, if the signatures are similar or even extremely similar, how to distinguish the responsibilities is complicated. After all, the shop assistants are not professional appraisers, but in this case, the more similar the signatures are, the less responsibility the merchants bear. According to the similarity of signatures, there should be differences in the division of responsibilities.
