What Should You Keep in a Passport Holder?

You have bought a passport holder — now what should actually go inside it? Used well, a passport holder is a compact travel command centre that keeps everything you need at your fingertips. Pack it wrong, and it becomes a bulky brick or a security risk. This guide explains exactly what to keep in a passport holder, what to leave out, and how to organise it so you breeze through every checkpoint. We will cover the essentials — passport, boarding pass, cards, cash, and SIM cards — plus smart packing tips.

The golden rule: essentials in, clutter out

A passport holder works best when it holds the documents and items you reach for during travel — and nothing else. Overstuffing it makes it bulky, slow to use, and painful to lose. Before each trip, pack only what you will genuinely need at airports, borders, and on arrival. Everything else belongs in your main wallet at home or in the hotel safe. With that principle in mind, here is what earns a place inside.

1. Your passport (the obvious one, done right)

Your passport is the centrepiece, and most holders have a dedicated full-size sleeve for it. Slide it in so the cover is protected and it sits flush without bending. A snug fit matters: too loose and it slides around, too tight and it is a struggle at the gate. Keeping your passport in the same slot every time also means you instantly notice if it is missing. If you travel as a couple or family, a larger holder can carry two passports together — just make sure each has its own clearly assigned spot.

2. Boarding pass and travel tickets

Your boarding pass is the document you present most often, so it deserves a front, easy-access slot. A printed boarding pass slips neatly into a passport holder and is always ready at security and the gate — no scrambling to reopen an app or find a screenshot. Keep any connecting tickets, train passes, or event tickets here too, ideally in the order you will use them. Even if you usually use a mobile boarding pass, a printed backup in your holder is a smart safeguard against a dead phone battery.

3. Cards: the right ones, not all of them

Card slots are where travelers most often overpack. The goal is to carry the cards you will actually use, not your entire wallet.

• One or two payment cards — ideally a credit and a debit card, kept in separate places where possible so a single loss does not strand you.
• Your ID or driving licence, if you need it as secondary identification.
• A travel insurance card or a note of the policy number.
• A transit or hotel card for your destination, if relevant.

Leave loyalty cards, store cards, and spare bank cards at home. Fewer cards means a slimmer holder, faster checkpoints, and far less to cancel if it goes missing. If your cards are contactless, an RFID-blocking holder shields them from unwanted scanning while they are tucked inside.

4. Cash (a little, in the right currency)

A passport holder is a handy place for a modest amount of cash — enough for a taxi, tip, or small purchase on arrival before you reach an ATM. Keep notes flat in a slot or a dedicated pocket, and favour smaller denominations for convenience. The key word is modest: a passport holder is not a safe, so do not carry large sums in it. Split your cash between your holder, your main bag, and the hotel safe so you are never caught out if one is lost. A holder with a zip pocket is especially useful for keeping coins and notes secure.

5. SIM cards and tech bits

SIM cards are tiny and notoriously easy to lose, which makes a passport holder an ideal home for them. When you swap to a local SIM or eSIM, store your original SIM in a card slot or small pocket so you can switch back when you return. Many travelers also tuck in a SIM-ejector pin. Keeping these with your passport means your connectivity essentials travel together with your most important documents — and you will not be hunting for your home SIM at the end of the trip.

What to leave out

Just as important as what to pack is what to skip:

• Large amounts of cash — split it up and use the hotel safe.
• Every bank and loyalty card — bring only what you will use.
• Sensitive documents you do not need daily — keep originals secured and carry copies.
• Bulky items — pens, keys, and chargers belong elsewhere; they wear out the holder and add bulk.

How to organise it like a pro

A little sequencing makes a big difference. Arrange items in the order you will use them:

• Front slots: boarding pass and ID — the things you present constantly.
• Passport sleeve: your passport, always in the same place.
• Middle slots: your main payment card and travel insurance details.
• Back or zip pocket: cash, SIM cards, and items you need less often.

This way you are never digging through everything at the counter, and you can tell at a glance if something is missing. For a complete travel-document routine, see our guide on how to organize travel documents.

Does capacity matter?

Yes — what you can keep inside depends on the holder you choose. Slim covers hold a passport and a card or two; multi-slot holders and travel wallets carry cards, cash, tickets, and even a second passport. If you like to keep everything together, choose a holder with several slots and a zip pocket. If you travel light, a slimmer design keeps bulk down. Our buying guide helps you match capacity to your needs, and you can compare options in the PortCase collection.

Smart extras worth tucking in

Beyond the core essentials, a few small extras can make travel smoother without adding bulk. Consider slipping in a folded copy of your travel insurance summary, a printed hotel address (handy for taxis and immigration forms), and a note of emergency contact details. Frequent flyers often add a vaccination or health card where required, a backup luggage tag, and a couple of contact cards. If your holder has a zip pocket, it is the ideal spot for a spare SIM, a SIM-ejector pin, or a single emergency banknote in a widely accepted currency. The trick is to keep these genuinely useful and genuinely small — anything bulky belongs in your bag, not your holder.

Keeping your packed holder secure on the move

Once your holder carries your most important items, protecting it becomes part of the routine. Keep it in an interior or zipped pocket rather than an outer compartment, especially in crowds. If your holder has a secure snap or zip closure, use it — an open holder is an invitation for items to slip out. When you are not actively using it, return it to the same place every time so you always know where it is, and do a quick passport-phone-wallet check whenever you stand up or move on. If your documents share space with a few contactless cards, an RFID-blocking holder adds a layer of protection against wireless scanning.

Frequently asked questions

Can you put cards and cash in a passport holder? Yes — most holders have card slots and a pocket for cash. Carry the cards you will use and a modest amount of cash; keep the rest secured separately.

Is it safe to keep cards in a passport holder? It is, especially with an RFID-blocking holder that shields contactless cards from scanning. Just avoid carrying every card you own in one place.

Can a passport holder fit two passports? Larger holders and travel wallets can. If you travel as a couple or family, look for one designed for multiple passports.

What should you not keep in a passport holder? Avoid large amounts of cash, every bank and loyalty card, bulky items like keys or pens, and sensitive documents you do not need daily — keep those secured separately or in the hotel safe.

The bottom line

The best-packed passport holder contains exactly what you need and nothing more: your passport, boarding pass, one or two cards, a little cash, and small essentials like a spare SIM. Organise them in the order you will use them, keep backups and surplus elsewhere, and choose a holder with the right capacity and RFID protection. Do that, and your passport holder becomes the most useful thing in your carry-on. Find one with the slots you need in the PortCase passport holder collection.
