RFID radiation test

Derrick Carter, a member of the GSFC Radiation Protection Office (RPO),  is taking Radiofrequency (RF) readings on one of the Global Precipitation Measurement (GPM) Constellation antenna systems in the building 19 anechoic chamber. Code 567 uses the anechoic chamber when analysing radiation patterns for spacecraft communications and other antenna characterizations.  Photo was taken by Ted Simmons  

RFID wallets are made with special RFID blocking textile that is made of 50% polyester, 23% copper and 27% nickel. This ensures that RFID chip cannot be read as it is protected inside this material. However, there are different frequencies for different RFID chips.

There are four main categories of RFID frequencies:

  • Low Frequency RFID is <135 KHz. This is what your access cards use to open doors.
  • High Frequency RFID is 13.56 MHz. This is being used by credit cards to pay for your goods.
    This is also the frequency for reading your passport information.
  • Ultra High Frequency (UFH) RFID is 868-870 MHz or 902-928 MHz
  • Super High Frequency (SHF) RFID is 2.400-2.483 GHz

What you need to know, is that High Frequency RFID is being shielded by Secret wallets.

How dangerous is RFID technology?

Digital pickpocketing is growing each year, experts are warning. If you want to know how easy it is to read your credit card information, just imagine that readers are available for less than$20. Application to read can be downloaded on any smartphone or computer. Hacker needs to stand less than 7 inches from the card while it is being read. Then a new machine is being used to write to a new hacked credit card with your information. And you don’t even know, this happened.
