The function of an RFID security sleeve.

An RFID security sleeve can help users prevent strangers from reading their IC bank cards, ID cards, and RFID smart cards, such as transit cards. It effectively eliminates risks of unauthorized charges, as well as personal privacy leaks, caused by NFC applications like Alipay Wallet.

What is RFID?

RFID stands for Radio Frequency Identification, which is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify target objects, enabling quick item tracking and data exchange.

What is NFC?

NFC (Near Field Communication) is a short-range, high-frequency wireless communication technology that allows electronic devices to perform non-contact, point-to-point data transmission and exchange.

Which bank cards can have their information read?

Bank cards that can be read by NFC-enabled phones are all IC chip cards; traditional magnetic stripe cards cannot be read.

NFC-enabled Phones and Chip Bank Cards

Bank cards with an IC chip on the surface usually also have a contactless payment symbol. When using such chip cards to pay at cafes or restaurants, you only need to tap the card near the reader to complete small payments without requiring a PIN.
