                                                             Product Introduction

The soft electromagnetic shielding material used in the card sleeve manufacturing is one of the national 863 public technology projects and has obtained 5 national patents. Tested by the 203rd Research Institute of the Ministry of Aerospace Industry of China and the Shanghai Testing Center of China, its shielding function is >65dB@10MHz; >85dB@100MHz, with an electromagnetic wave rejection rate of 99.9999998%, reaching the international leading level.
Card sleeves can effectively prevent the magnetic stripe from disappearing or information from being leaked on bank cards, second-generation resident ID cards, information cards, social security cards, etc., thus avoiding the inconvenience, embarrassment, or danger that may be caused to people's daily lives, as well as the harm to the human body caused by electronic and electromagnetic waves.
Precautions for use: Simply insert the cards that require protection into the sleeve to protect and keep them confidential; avoid contact with acidic or alkaline liquids; if accidentally wetted, allow to air dry before continuing to use; prevent puncture by sharp objects.

I. Main Functions:
1. Prevent interference from strong static electricity
2. Prevent damage from strong electromagnetic fields
3. Prevent others from maliciously reading or stealing your personal information.
4. Extend the effective lifespan of smart cards

II. Product Introduction:
The "aluminum foil RFID card sleeve" effectively shields various magnetic cards and IC cards from strong electromagnetic fields, static electricity, and high-temperature radiation, preventing scratches and distortion. Furthermore, the "close-fitting protection" also shields the electromagnetic signals of contactless IC cards, preventing malicious individuals from using various card readers to steal your documents, especially your ID card information, for illegal purposes.

III. Scope of Application:
"Aluminum foil RFID card sleeve" is suitable for shielding and protecting various cards from electromagnetic interference;
1. Applicable to the protection and confidentiality of second-generation ID cards;
2. Applicable to preventing damage to the chip circuit of various contactless IC cards, and preventing information leakage and theft from contactless IC cards;
3. Suitable for preventing damage to various IC card chips or IC card circuits, thus avoiding the loss of information on the IC card;
4. Suitable for preventing the magnetic stripe of magnetic cards from being damaged by electromagnetic waves, resulting in information loss.

IV. Product Technical Performance and Features:
1. Possesses remarkably high shielding effectiveness: >65dB@10MHz; >85dB@100MHz
2. Possesses excellent antistatic properties: no static electricity is generated, and the surface resistance is <0.02.
3. Excellent abrasion resistance: shielding effectiveness does not decrease after >10,000,000 abrasion cycles.
