Best passport holders: what to buy, and what to skip

Every holder on this page advertises RFID blocking, which means it cannot possibly be a reason to choose between them. It is worth understanding what it is and is not doing, because the marketing has outrun the facts by about twenty years.

1. The passport already shields itself. When the US introduced the electronic passport, the published rule described anti-skimming material in the front cover and spine, specifically to mitigate skimming. A closed e-passport is substantially harder to read than an open one by design - that protection is in the document, not in your wallet.
2. The chip is not readable without the printed page. US e-passports use Basic Access Control, which works like a PIN taken from characters printed on the data page, and which also encrypts the communication between the chip and the reader. Someone who has not physically opened and photographed your passport does not have the key.
3. The read range is a few inches. The chip is designed to be read with the document within roughly 10 centimeters of a reader. "Walking past you in a crowd" is not the threat model the technology supports.
4. Where the shield does earn its place: contactless cards. The thing in your travel wallet that genuinely broadcasts at short range is a tap-to-pay card, not the passport. If you keep cards in the holder, a blocking layer is a small, free piece of belt-and-braces - which is exactly how you should value it.

A passport book is a standardized object. ICAO Doc 9303 sets the TD3 travel document at 125 x 88 mm - about 4.9 x 3.5 inches - which is why a cover cut for one country's booklet mostly fits another's. "Mostly" is the problem. A sleeve a couple of millimeters short will gape at the corner and the booklet will work itself loose over a long day of standing up and sitting down.

• Check the listing says US passport, if you hold one. Several popular covers are cut snug for EU booklets and advertise the fact. A snug cover that needs force is worse than a loose one, because forcing the cover is what bends the chip page.
• Prefer a closure to a sleeve. A snap, a zip or a genuine bifold tension all keep the book in. An open slip-in sleeve relies on friction, and friction loses to a bag being swung onto a train luggage rack.
• Count the cards you will really carry. Two or three. A card behind the booklet lifts it off flat and makes it harder for an agent to scan, which is the most common cause of being asked to take the passport out of the cover entirely.
• Do not laminate or over-stiffen. Anything that adds rigidity over the data page risks the machine-readable zone and the chip. The holder's job is to carry the booklet, not to armor it.

One more practical point: your passport does not count as a liquid, but the things that ruin it travel next to the things that do. Keep the document wallet out of the same packing cube as anything that can leak, and keep your liquids where you can reach them - the TSA liquid rules explain why that bag has to come out anyway.

Yes, for one specific reason, and no for the reason the listings imply. A tracker will not recover a stolen passport - a thief who wants the booklet will discard the wallet, and following a stolen document to an address is not a thing you should ever do. What a tracker is genuinely good at is the far more likely failure: you left the wallet somewhere. A seat pocket, a hotel safe, a restaurant table, the tray at security.

In a populated place - which is where airports and hotels are - a Bluetooth tracker reports its position through other people's phones with useful accuracy, and the "left behind" alert is the feature that actually saves the trip. In an empty place it reports nothing. That is the honest shape of the benefit, and it is worth a dollar or two of extra cost in a holder, not a premium.

If you are buying trackers anyway, the same logic and the same hardware apply to the bag the wallet is in - the best luggage trackers covers which ones work on which phone, and are luggage trackers worth it is the honest version of the question.

The best holder used badly loses a passport; a cheap holder used consistently does not. Three rules worth more than any product on this page.

1. One pocket, every time. Pick the pocket before you leave the house and never improvise. Most lost passports are not stolen, they are set down.
2. Never in the overhead bin. The passport travels on your body or in the bag at your feet. A bin bag can be moved by a stranger, gate-checked, or left behind in a scramble.
3. Split the risk. Passport and primary card in the holder; a backup card and some cash somewhere else entirely. If you are carrying everything in one wallet, one loss ends the trip - which is the single argument against the family holder above, and worth weighing before you buy it.

If the document wallet is the last gap in your kit, the rest of it is in long-haul flight essentials and travel essentials for women - and the bag it all goes in is in best personal item bags.

Worth reading once before you need it, because the order of operations is not obvious and the first step is the one people skip.

1. Report it lost or stolen. The report is made on Form DS-64, and the important consequence is immediate: once reported, that passport is invalid forever. Even if it turns up in a jacket the next day you cannot travel on it again. Report it anyway - an unreported booklet in circulation is the actual identity risk.
2. Contact the nearest US embassy or consulate and ask for the consular section. They have after-hours duty officers for genuine emergencies. The Embassies and Consulates tool on travel.state.gov gives you the address, phone number and hours for the country you are standing in.
3. File a local police report if you can. Guidance varies on whether it is required, but it costs you an hour and it documents the loss for the consulate, your insurer and any onward carrier.
4. Apply for the replacement with both forms. Replacing a passport from abroad takes a DS-64 and a DS-11 together, plus photos and whatever proof of citizenship and identity you can assemble - which is why a photo of the data page on your phone and a paper copy in your luggage are worth the two minutes they take.
5. Ask about an emergency limited-validity passport if you are flying soon. A consulate can issue one for urgent travel, valid for a year or less, which you exchange for a full-validity book once you are home.

A document wallet is the cheapest thing in your luggage and the one you will miss first. The most expensive thing is the bag, and the brand that sells the most of it in the $100-$160 bracket is worth understanding before you buy - the SwissGear luggage review covers which of its models are worth it, and SwissGear vs Samsonite settles the head-to-head.
