An RFID wallet is a wallet built with shielding material, typically aluminium or carbon fibre, that blocks radio frequency signals from reaching your cards. This prevents unauthorised readers from scanning your contactless card data while the cards are inside the wallet.
Quick answer RFID stands for Radio Frequency Identification, the technology behind tap-and-go payments. An RFID blocking wallet shields your cards from unauthorised scans. The risk of skimming in everyday Australian life is low, but for international travel or peace of mind it is a practical and permanent precaution. Secrid wallets, which we stock at Blowes, use a structural aluminium card slide rather than a decorative lining, making them one of the more reliable constructions available.
What does RFID mean?
RFID stands for Radio Frequency Identification. It is the technology behind tap-and-go payments: PayWave, PayPass, and contactless everything. When you tap your card at a terminal, the card's chip broadcasts a signal at 13.56 MHz that the reader picks up in a fraction of a second.
That same signal can, in theory, be picked up by anyone with a reader device nearby, not just the terminal you are tapping on. This is the risk that RFID blocking wallets are designed to address.
Your contactless bank cards, electronic passport, Opal card, Myki card, and some building access badges all use RFID. If your card has the wave symbol (three curved lines, similar to a wi-fi logo turned sideways), it is RFID-enabled.
What is RFID skimming?
RFID skimming is when someone uses a portable reader to scan your contactless cards without your knowledge or consent. Because RFID readers do not need to physically touch your wallet, a thief could scan your card data in a crowded space: a busy airport queue, a packed train, a market, without you ever noticing.
The stolen data could then be used to clone a card or make fraudulent purchases online.
That is the threat in principle. How likely it is in practice is a separate question.
Is card skimming a real risk in Australia?
The honest answer: the risk is low, but it is not zero.
Modern Australian bank cards use encrypted, one-time transaction codes. Even if someone intercepted the signal from your card, the data captured would be largely useless for authorising a new transaction. ASIC MoneySmart notes that Australian banks typically reimburse customers for fraudulent contactless charges, though disputes can still be stressful and time-consuming.
The risk increases meaningfully when travelling internationally. European metro stations, South-East Asian markets, and major transit hubs are the environments most commonly associated with skimming incidents.
For day-to-day life in Australian cities and For anyone who travels internationally with any regularity, or who simply wants to remove the risk entirely, an RFID blocking wallet is a practical and inexpensive solution.
Does my credit card have RFID?
Yes, almost certainly. If your card has the contactless payment symbol, three curved lines resembling a sideways wi-fi logo, it contains an RFID chip. The vast majority of Australian bank cards issued in the last several years are contactless-enabled. Your electronic passport also contains an RFID chip, as do most public transport cards including Opal and Myki.
Does my credit card have RFID?
Yes, if your wallet does not have RFID shielding. A contactless card sitting in a standard wallet can be read by any RFID reader that gets close enough, typically within a few centimetres for payment cards, though some readers can operate at greater distances for passports and access badges.
An RFID blocking wallet prevents this by absorbing or reflecting the radio signal before it reaches your cards.
Do RFID blocking wallets actually work?
Yes, when they are made properly. The shielding material is the key variable. Aluminium and carbon fibre reliably block the 13.56 MHz frequency used by contactless cards and passports. A wallet that claims RFID protection but uses only a thin decorative lining may not provide meaningful protection.
The simplest test: put your card inside the wallet and try to tap it on a payment terminal. If the reader does not register, the wallet is working. If it does register, the shielding is insufficient.
Secrid wallets use an aluminium card slide as their core mechanism. The shielding is structural, built into the component that holds the cards rather than added as a separate layer. This makes it one of the more reliable implementations available, and it is straightforward to test: the card simply will not tap while inside the slide.
Do RFID blocking wallets damage your cards?
No. RFID blocking wallets do not damage cards, demagnetise magnetic strips, or interfere with chip-and-pin functionality. The shielding only blocks incoming radio signals. It does not emit anything, and it does not affect the card's data or physical components.
Will an RFID wallet block my Opal or Myki card?
Yes. Opal, Myki, and most other public transport cards use the same 13.56 MHz frequency as payment cards. If your transport card is stored inside the shielded section of your wallet, you will need to remove it to tap on and off. Some wallets address this with an external card pocket outside the shielded area, which is worth looking for if you tap multiple times a day.
Can RFID wallets go through airport security?
Yes, without any issues. RFID blocking wallets go through X-ray scanners and metal detectors without triggering alerts and without affecting the wallet's shielding properties. The materials used, typically aluminium and carbon fibre, are standard in carry-on luggage.
What is the difference between an RFID wallet and a regular wallet?
Functionally, nothing, except one contains a layer of shielding material. You use it the same way. The only practical difference is that you need to remove your cards to tap them, because the wallet is actively blocking the signal.
For most people this is not an inconvenience. For commuters who tap on and off public transport several times a day, keeping your transport card in a pocket outside the shielded section is the straightforward solution.
Do you actually need an RFID blocking wallet?
You probably do not need one if you live and work in Australia, carry modern bank cards, and do not travel internationally through crowded transit systems. Australian banks cover most contactless fraud, and the encrypted transaction codes on modern cards make intercepted data largely unusable.
It is worth having if you travel internationally with any regularity, carry an electronic passport or older access card, or simply want to remove the possibility entirely. At the price point of a quality wallet, RFID protection is not the primary reason you are buying it. It is a feature that is there when you need it.
It is genuinely useful if you carry government-issued ID, building access cards, or transport cards that use older RFID technology without the same encryption layers as modern bank cards.
What to look for when buying an RFID blocking wallet
Shielding material. Aluminium and carbon fibre are the most reliable. Fabric-lined wallets vary significantly. If the spec does not mention the specific material, test it before relying on it.
Structural vs decorative shielding. The best RFID wallets build the shielding into the card-carrying mechanism itself. Wallets that add a thin lining to an otherwise standard construction offer weaker and less consistent protection.
Size and carry. A slim card holder works for city life. A travel wallet with passport capacity is worth it if you move through airports regularly. Think about what you actually carry, not what looks good on the shelf.
Wallet vs sleeve. If you have a wallet you already like, an RFID sleeve for a single card or your passport is a practical alternative to replacing everything. A sleeve for your passport specifically is useful if you travel internationally but are otherwise happy with your current wallet.
Test it on arrival. Put your card inside and try to tap it on a payment terminal. If the reader does not register, the shielding is working.
The Secrid range at Blowes
We stock the full Secrid range, including the Miniwallet, Slimwallet and Cardprotector, in store and online. Secrid is a Dutch brand that builds RFID protection into the aluminium card slide at the core of every wallet.
The shielding is structural, not cosmetic. The same aluminium component that ejects your cards is what blocks the signal. It is straightforward to test and consistently reliable across the range.
Frequently Asked Questions (FAQ)
Do I need an RFID blocking wallet in Australia?
For everyday use in Australia the risk is low. Modern bank cards use encrypted one-time transaction codes that make intercepted data largely useless, and Australian banks typically cover contactless fraud. For international travel or additional peace of mind, an RFID blocking wallet is a practical and inexpensive precaution.
What is RFID in a wallet?
RFID (Radio Frequency Identification) is the technology that powers tap-and-go payments. In a wallet context, RFID refers to the shielding layer built into the wallet that prevents contactless signals from reaching your cards, stopping unauthorised readers from accessing your card data.
Are Secrid wallets RFID protected?
Yes. Secrid wallets use an aluminium card slide that physically houses and shields your cards. The shielding is structural, built into the ejection mechanism rather than added as a separate lining, which makes it one of the more reliable and consistent implementations available.
Do RFID blocking wallets damage cards?
No. RFID blocking wallets do not damage cards, affect magnetic strips, or interfere with chip-and-pin transactions. The shielding blocks incoming radio signals only. It does not emit anything or affect the card's data or components.
Will an RFID wallet block my Opal or Myki card?
Yes. Opal and Myki cards use the same 13.56 MHz frequency as contactless payment cards. You will need to remove the card from the shielded section to tap it. Some wallets include an external card slot outside the shielded area for this purpose.
Can RFID wallets go through airport security?
Yes, without issue. RFID blocking wallets pass through X-ray scanners and metal detectors without triggering alerts and without affecting the wallet's shielding.
How do I test if my RFID wallet is working?
Put your card inside the wallet and try to tap it on a payment terminal or card reader. If the reader does not register the card, the shielding is working. If it does register, the shielding is insufficient.
How common is RFID credit card theft in Australia?
Confirmed cases of RFID skimming in Australia are rare. The Australian Federal Police have identified airports and busy tourist areas as higher-risk environments, but for everyday domestic use the threat is low. The risk increases during international travel, particularly in crowded transit systems in Europe and South-East Asia.
What is the difference between an RFID wallet and a regular wallet?
A regular wallet stores cards physically but offers no protection against radio frequency scanning. An RFID wallet adds a shielding layer that prevents contactless readers from accessing your cards while they are inside. Functionally they work the same way. The only practical difference is that you need to remove your card to tap it.
