Have you ever wondered why you put a coin next to you when you make a copy of your ID card? The reason behind this little action is not only surprising, but also very mysterious!
The importance of ID cards
ID cards, as a "status symbol" for each of us, play an irreplaceable role in life. It not only represents our legal identity, but is an integral part of our daily lives. From taking high-speed trains and planes, to applying for bank cards and mobile phone numbers, all show the importance of ID cards.

However, when we make copies of our ID cards in case we need them, we may unknowingly expose our privacy. Criminals can obtain our personal information through photocopies, so as to carry out fraud, identity theft and other illegal acts. It's like a hidden danger buried in life.
The magic of the coin
To prevent this from happening, there is a simple and effective way: when making a copy of your ID card, place a coin next to it. This seemingly ordinary small action actually has a huge effect. A three-dimensional imprint of a coin appears next to the photocopied ID document, which is visually distinct.
The anti-counterfeiting effect is remarkable
Due to the three-dimensional effect of the coin, a unique mark is formed on the copy, making the copy a "unique" document. If someone tries to make a copy of this copy again, it will be difficult for the three-dimensional coin to be reproduced in its entirety. This method effectively avoids the possibility of the copy of the ID card being abused by criminals.
Other protective measures
In addition to placing coins, there are other things we can do to protect our identity. For example, it is possible to overwrite some sensitive information when making copies, or to label copies for specific purposes, such as "for bank account opening only", and to destroy them as soon as they are finished.
