RFID-blocking sleeves block one frequency at 13.56 MHz. Faraday bags block the full mobile-radio spectrum from 30 MHz to 10 GHz. The difference matters when your threat model includes more than just credit-card skimming. Here is the precise distinction, where each tool fits, and the buyer mistake that almost everyone makes.
RFID blocking and Faraday shielding are not synonyms. RFID blocking is a narrow defense against one frequency band (13.56 MHz HF) used by contactless credit cards, biometric passports, and corporate access badges. Faraday shielding is a full-spectrum defense from 30 MHz to 10 GHz that covers 18+ different consumer wireless protocols including all cellular bands, all WiFi standards, Bluetooth, GPS, NFC, RFID, and key-fob LF/UHF. RFID-blocking sleeves are appropriate for wallet-only protection at $5–$20; Faraday bags address every threat for $50–$300.
The marketing confusion runs in both directions. Some "RFID-blocking" wallets are actually full-spectrum Faraday products (over-engineered for the task they're sold for). Some "Faraday-rated" cheap pouches are actually only RFID-blocking (under-engineered for what they imply). The label alone does not tell you what you're getting. The dB number across a stated frequency range is what tells you what you're getting.
This is the operational reference. If a threat falls inside the green column, the corresponding product blocks it. If it falls outside, it does not.

This is the single most common misconception in the entire personal-privacy product category. The answer is no, and it has been no since RFID-blocking wallets first appeared in the early 2000s. Yet the marketing language across the industry has consistently implied "blocks signals" without specifying which signals.
The wallet blocks the 13.56 MHz HF band, which is the frequency contactless cards and biometric passports operate at. That is the full extent of what it does. It does not block your phone, because phones do not operate at 13.56 MHz. The phone you put in your "RFID-blocking" wallet pocket is broadcasting cellular, WiFi, Bluetooth, and GPS at frequencies the RFID material does not even attempt to attenuate.
In 2010, RFID skimming was the dominant wireless threat for ordinary consumers and the wallet category solved that threat. Phones were not the surveillance vector they are today. Fifteen years later, the threat surface has moved entirely — AirTag stalking, IMSI catchers, key-fob relay attacks, hotel-WiFi MITM — and the wallet category has not moved with it. The product label survived the threat shift.
If your only concern is wallet-content protection, RFID sleeves are still correct and still affordable. If you have any other concerns — phones, key fobs, AirTags, multi-device travel — you need a Faraday product rated for the full spectrum. The two product categories serve different jobs. Most executives end up with both: RFID sleeves around the wallet they carry through the office, plus a Faraday briefcase for travel and overnight storage.
Three independently shielded chambers — laptop, tablet+phone, wallet+keys. 76–85 dB attenuation across 30 MHz – 10 GHz. Strict superset of any RFID-blocking sleeve plus full coverage of cellular, WiFi, Bluetooth, GPS, key-fob LF, AirTag BLE, NFC, UWB. Made in the United States. $129 with free U.S. shipping.
