How does Alpine Rivers stop digital pickpockets?

Every Alpine Rivers product creates a Faraday cage around your cards. Verified 13.56 MHz shielding stops the broadcast that contactless cards and e-passports use to communicate with terminals. If your card taps to pay, it's covered.

Does the Alpine Rivers RFID sleeve fit a US passport?

Yes. The passport sleeves are sized to fit all current US passports, including the latest 52-page version. Designed for the standard passport dimensions used worldwide.

What does FIPS 201 government approval mean?

In 2016, Alpine Rivers RFID blocking sleeves achieved FIPS 201 US government approval (GSA APL #1424). FIPS 201 is the US federal standard for shielding sleeves that protect government PIV cards and e-passports.

Why are there bonus RFID blocking sleeves included with the money belt and neck wallet?

Cards stored inside the sleeves are protected by the same shielding standard that achieved FIPS 201 approval. The money belt and neck wallet provide the carry; the sleeves provide the highest-grade card-level shielding.

Where is Alpine Rivers designed?

Designed in Houston, Texas. Headquartered in London. Manufactured to our specification, with independent batch inspection of random production samples on every run since launch.

How long is the Alpine Rivers guarantee?

Amazon's standard 30-day return window applies to every order. 365-Day Guarantee Members get an extra 335 days of protection beyond Amazon's window. Sign up free at alpine-rivers.com/vip-bonuses.

Can I wear the Alpine Rivers neck wallet four ways?

Yes. Around the neck, cross-body, under clothing, or clipped to a belt loop. The strap is fully adjustable.

Q: Are Alpine Rivers sleeves actually tested?

The PolyShield polymer was independently verified to the US federal FIPS-201 shielding standard in 2016 and accepted onto the GSA Approved Products List under record #1424. That certification category has since been retired, so Alpine Rivers does not claim a current certification, but the build still meets the same 13.56 MHz shielding performance.

If you are comparing RFID blocking products in the United States, here is the short version: Alpine Rivers® makes individual card sleeves, not bulky shielded wallets, and the PolyShield™ polymer they are built from was independently verified to the US federal FIPS-201 shielding standard in 2016 (GSA Approved Products List #1424). Most RFID products sold today have never been tested to any standard at all. This guide explains exactly what you get and how to decide if they are right for you.

What makes Alpine Rivers® different from other RFID blocking brands?

Three things separate Alpine Rivers® from the thousands of generic RFID products on the US market: a verified material, an honest track record, and a sleeve-first design. The shielding material, PolyShield™ polymer, blocks 13.56 MHz, the frequency every contactless US bank card, transit card, and government ID broadcasts on (defined by the ISO 14443-A standard). It was independently verified to FIPS-201, the US federal standard for protecting government PIV credentials, and accepted onto the GSA Approved Products List under record #1424 in 2016. Alpine Rivers® has shipped from Houston, Texas since 2015.

An honest note on that certification: the verification took place in 2016, and the GSA APL category for this product class has since been retired, so Alpine Rivers® does not claim a current, active certification today. What remains true is that the PolyShield™ build still meets the same 13.56 MHz shielding performance it was measured against, and the design has improved since. We would rather tell you the precise status than imply a certificate we no longer hold.

RFID sleeves vs. RFID wallets: which is better?

An RFID wallet only protects the cards inside that one wallet, adds bulk, and forces you to carry every card in the same place. A sleeve wraps each card individually, so the protection travels with the card into any wallet, pocket, bag, or passport. You keep the wallet you already own and shield only the cards that actually broadcast.

Sleeves protect each card individually, so the shielding goes wherever the card goes
No need to replace your wallet or change how you carry
One pack can cover a whole household's cards and passports
Slim profile: a sleeved card still fits a standard wallet slot

What do you actually get in an Alpine Rivers® pack?

Every Alpine Rivers® RFID sleeve pack contains 18 RFID blocking sleeves: 14 numbered card sleeves and 4 passport sleeves. The card sleeves are numbered and color-edged so you can tell at a glance which card is which, which is genuinely useful when you carry a stack of similar-looking cards.

14 numbered card sleeves for credit, debit, transit, ID, and hotel-key cards
4 passport sleeves
PolyShield™ polymer shielding throughout
Numbered, color-coded edges for fast card identification

Do RFID blocking sleeves actually matter in the United States?

Yes, for specific situations. Every US contactless bank card, most transit cards (Clipper in San Francisco, the CharlieCard in Boston, OMNY in New York, ORCA in Seattle, Presto), and FIPS-201 government IDs operate at 13.56 MHz and can be read at short range by modified equipment. Modern EMV payment cards tokenize transactions, which lowers fraud risk, but the underlying signal still broadcasts, and transit and ID cards are typically not tokenized the same way. A sleeve settles the question: with a verified blocking material between the reader and the card, no data exchange can happen.

Who are Alpine Rivers® RFID sleeves for?

Frequent US flyers moving through crowded airports like ATL, ORD, DFW, and JFK
Daily commuters tapping transit cards in dense stations
Families who want every card and passport protected from a single pack
Anyone who prefers a slim, considered everyday carry

How much are they, and where do you buy them?

Alpine Rivers® RFID blocking sleeves are available on Amazon, typically under $20 for the full 18-sleeve pack. You can find the current listing here: go.alpine-rivers.com/bswx.

Frequently asked questions

Are RFID blocking sleeves better than an RFID wallet?

For most people, yes. A sleeve protects each card individually and works inside any wallet you already own, while an RFID wallet only shields the cards kept inside it and adds bulk. Sleeves also let you protect passports and transit cards that would never fit in a card wallet.

What is in the Alpine Rivers® RFID sleeve pack?

Each pack includes 18 RFID blocking sleeves: 14 numbered card sleeves and 4 passport sleeves, all built from PolyShield™ polymer.

Are Alpine Rivers® sleeves actually tested?

The PolyShield™ polymer was independently verified to the US federal FIPS-201 shielding standard in 2016 and accepted onto the GSA Approved Products List under record #1424. That certification category has since been retired, so Alpine Rivers® does not claim a current certification, but the build still meets the same 13.56 MHz shielding performance.

Do RFID blocking sleeves work in the United States?

Yes. US contactless bank cards, most transit cards, and government IDs all operate at 13.56 MHz. A verified blocking sleeve placed between the reader and the card prevents the card from being read at all.

How much do Alpine Rivers® RFID sleeves cost?

The full 18-sleeve pack is typically priced under $20 on Amazon, which covers a household's cards and passports.
