Did you know what are RFID cards? These cards operate at different frequencies: low and high. We will list the frequencies at which the main types of contactless cards work. 

Not all RFID cards are the same

There are two types of cards: RFID contactless cards with 125KHz and 13.56Mhz frequency chips. 

The first type of chip is called Low Frequency (LF), second – High Frequency (HF).

Low Frequency (LF) RFID chip

125KHz. It is used in the Access control field, identification field, and safety management. 

  • Old ID cards.
  • Old access cards.
  • Safety management systems.

Contactless bank card. To protect such card it is better to use RFID blocking cards

High Frequency (HF) RFID chip

13.56MHz. It is used in high-security request fields. 

  • Newer debit and credit cards.
  • Passports.
  • New ID and access cards.
  • Hotel keys.
  • Transit cards.
  • Cards with these symbols RFID contactless payment symbol NFC symbol

Blocking RFID cards with 125KHz and 13.56Mhz chips. One solution for all frequencies

Is there a solution that will protect all contactless cards from both 125KHz frequency and 13.56Mhz frequency chips at the same time? Yes. It is RFIDsecur™ RFID blocking card. It will protect both types of contactless cards. The cards are made of a special composite film: RFIDsecur ™Composite Film. One simple material with no complications. 

RFIDsecur™ fabric was developed and tested in the UK, with testing undertaken at Plymouth University Brunel department and it is manufactured in the UK.
