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.
High Frequency (HF) RFID chip
13.56MHz. It is used in high-security request fields.
- Newer debit and credit cards.
- New ID and access cards.
- Hotel keys.
- Transit cards.
- Cards with these symbols
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.
