No, this is an active jamming device, and as the other readers indicate, may only work at a particular frequency or communications protocol.
However Smart Tools offers an RFID Shield - a passive device that prevents your RFID card from being detected or communicating, and is independent of frequency or protocol. There's info and a picture at:

Allay RFID privacy concerns by letting the end user decide when it transmits
There is a concern that RFID tags embedded in credit cards
may make the presence of such cards detectable by anyone with
an RFID reader.
To answer that concern, we have an easy way to make RFID
tagged cards normally invisible, but active when you want them to be.
Background: RFID tags are appearing everywhere. They can be
embedded in plastic cards such as credit cards, id cards,
passports and other places. There are privacy concerns
about these tags being read without the owners knowledge.
Solution: "RFID Shield" lets you choose when your tags are readable.
