The places you actually need RFID protection are not abstract. They are specific, repeatable moments in international travel where you are carrying valuables, surrounded by strangers, often distracted, sometimes tired. Here is the airport-to-hotel arc, with what to do at each step.
At the departure airport
Documents and cards stay on you, not in checked bags. A neck wallet holding passport, boarding pass, and a primary card sits under your top layer and goes through security exposed.
For body scanners: the metallic shielding inside an Alpine Rivers® product may register on a millimeter-wave or backscatter scanner. Most travelers walk through with the neck wallet on and explain it as a passport carrier. Some prefer to remove it and put it through the X-ray. Either is fine. Inside the carrier, sleeves protect each card while it sits there.
For X-ray: shielding is not solid metal. It will not block X-ray imaging or trigger an alert. Security officers will see the contents on screen.
On the plane and during connections
This is where casual exposure matters most: long lines for connections, crowded gate areas, restaurants where you set bags down. A neck wallet kept under a layer is your anchor. Cards you are not actively using stay sleeved inside.
Airport lounges and gate-area cafes are real environments where industrial skimmers in payment terminals have been documented. Tap your card directly on the official terminal, not on third-party tablets that look like point-of-sale devices. Your card is exposed during the tap itself, only briefly, and EMV tokenization protects the data even then.
At the destination airport
Border control: present your passport directly. The chip is read by official equipment in proximity. After passing through, return the passport to the shielded compartment.
Ground transport: taxis, ride-shares, and trains are the highest-density opportunistic skimming environments after transit hubs. If you are carrying a backpack, keep cards out of outside pockets, sleeved and inside the main compartment. Money belt or neck wallet stays on body.
At the hotel
Hotel keycards in 2026 vary by property. Newer locks (Assa Abloy, dormakaba, Salto) are 13.56 MHz NFC with strong encryption. Older locks (some independent properties) use weaker schemes that have been documented as vulnerable to relay or replay attacks.
Storing your hotel keycard in a sleeve when not in use is a small, low-cost defense against the older-vendor risk. It also prevents the keycard's own radio activity from interfering with payment cards in the same wallet, which is a real but minor source of card-in-wallet read confusion.
In urban markets, festivals, and crowded transit
This is the highest-risk environment for opportunistic mobile skimmers. The defense is the same as for pickpocketing: keep valuables on body, not in outside pockets, and shielded.
A money belt under clothing puts cards and cash beyond a casual reach. The shielding ensures the cards do not respond to a hand-held reader walked past you in the crowd. The combination is what makes a money belt the right tool here, even though it is overkill for casual day-to-day use.
At restaurants and bars abroad
Always tap or insert your card on the visible terminal. Be wary of staff taking the card to the back to process payment. If you must hand over the card, the brief exposure is minor, but the risk profile is no different from at home.
Transit cards in major cities
London Oyster, NYC OMNY, Tokyo Suica, Paris Navigo: all use 13.56 MHz contactless. Keep them in a separate sleeve from your payment cards to avoid confusion at gates. Sleeve them when not in use to prevent any unwanted read.
The summary checklist
- Wear shielded carry on body (money belt or neck wallet) during transit days
- Sleeve every contactless card individually
- Sleeve your hotel keycard when not in use
- Keep the passport shielded at all times when not actively presenting
- Do not store cards in outside backpack pockets, even sleeved (pickpocket-first risk)
- Tap directly on visible payment terminals; do not hand over cards
