What's the RFID blocking card passport sleeve?

An RFID blocking sleeve is a protective cover designed to prevent unauthorized access to information stored on RFID (Radio Frequency Identification) chips. These chips are commonly found in items such as credit cards, passports, and ID cards. The sleeve is typically made from a material that blocks electromagnetic signals, thereby preventing skimming devices from reading the RFID chip's data. Key features and benefits of an RFID blocking sleeve include:

1. Security: Protects against electronic pickpocketing and identity theft.
2. Privacy: Ensures personal information on RFID-enabled cards and documents remains private.
3. Convenience: Easy to use by simply sliding the card or document into the sleeve.
4. Portability: Compact and lightweight, making it convenient for everyday carry in a wallet, purse, or pocket.

These sleeves are often made from materials like aluminum, carbon fiber, or specially designed fabrics that can effectively block RFID signals.
