Blocking Experiments
According to physics, the aluminum shielding inside of the RFID shield is really effective at blocking 13.56Mhz RFID chips, and pretty good at shielding other frequencies as well. Empirical testing so far has shown that the RFID shield either completely blocks or seriously inhibits RFID reading.
The following tests have been done:
- The 7-11 Checkout
- Financial Firm Employee Door Access
- New York/New Jersey PATH Card
- Cornell University student dorm access
Having limited resources of time and access to RFID equipment, it will be difficult to show exactly how well the RFID works with the wide number of RFID devices out in the world. You could of course purchase one yourself and satisfy your own curiosity. However, we would like to see how well it performs with various types of RFID devices and readers as well, so we have an offer to make.
We will provide you with a free RFID shield for either passports or credit cards if you perform a proper experiment and write up the results. We ask you to:
- Perform an experiment with a publically accessible RFID device and reader that has not been profiled here yet
- Write a 3+ paragraph writeup of the expriment, including distance of reading without any shielding and how effective the RFID shield was at stopping the reading of the data contained on the device
- At least one photograph or video of the experiment.
If you would like to receive a free RFID shield to perform this experiment, please .
