Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a card holder for preventing electronic information from being stolen. Background technique [0002] At present, the short-distance high-frequency wireless communication technology (NearField Communication, referred to as NFC) develops rapidly, and can realize non-contact point-to-point data transmission between electronic devices for data exchange. This technology has been well applied in many aspects such as bus cards, student cafeteria meal cards, prepaid cards, etc. When the card is placed close to the card reader, functions such as reading and payment can be completed. However, if this technology is used abnormally, the important information in the card will be stolen by criminals. It has been reported that electronic devices equipped with short-distance high-frequency wireless communication applications, including smart phones of ordinary people, are very cl...

Problems solved by technology

However, if this technology is used abnormally, the important information in the card will be stolen by criminals.

It has been reported that electronic devices equipped with short-distance high-frequency wireless communication applications, including ordinary people's smart phones, are very close to chip cards (including IC bank cards, documents with storage and memory functions, etc.) A large amount of information in the card can be obtained without contact. For bank cards, it may cause important private information such as the last few digits of the card number, electronic cash balance, part of the ID card, and transaction records.
