When we use credit cards, we often need to sign with a pen at the signature place. So, what kind of pen do we choose to sign? Generally speaking, a signature pen needs to have the following characteristics.

First of all, the pen needs not to be dehydrated easily. As we know, the material of credit card is relatively smooth. If you use an ordinary water-based pen, it can't be attached to the material and is easy to dehydrate. So we need to choose pens that are not easy to dehydrate, such as oily pens.

Secondly, the signature pen needs to have a good anti-counterfeiting effect. In order to prevent credit cards from being stolen, many credit card companies will print anti-counterfeiting marks on the card surface. Choose a pen with anti-counterfeiting function and strengthen prevention at the signature.

Finally, the pen should be light and easy to carry. We can choose a pen with a thin refill, which is convenient to carry with the bag. At the same time, you can also choose the pen with aluminum alloy body, which is light and durable and convenient to carry around.

To sum up, when signing a credit card, we should choose a pen that is not easy to dehydrate, has good anti-counterfeiting effect and is portable and easy to carry. This can not only ensure the effect of signature, but also enhance the anti-theft ability of credit card.
