What do you need to have with you when going on a tourist trip or a business trip? Toothbrush? A razor? Change of underwear? All these, no doubt, important little things are easy to buy in any supermarket. The main thing is finances, which will allow you to do this, and a reliable and convenient wallet for a trip.
RFID technology and contactless payment cards
More and more people today prefer to use bank cards as an alternative to cash. It is really convenient both in terms of comfort of use and wearing, and in terms of protecting finances from theft. After taking possession of someone else's plastic card, an attacker will not be able to use it without knowing the pin code. Or can it?
RFID technology, widely used in various fields of activity, has recently been actively used in payment systems. We are talking about contactless payment cards that allow you to pay for goods simply by touching the terminal and without the mandatory introduction of a pin code for purchases less than $ 15.
RFID Vulnerability Issues
The essence of RFID technology (radio frequency identification technology) is in the transmission of signals through radio waves. Information is exchanged between the scanner (active element of the system) and the tag (passive sensor on the card) at the request of the terminal, after which the system gains access to the client's account and debits money from it.
Now imagine that such a scanner is in the hands of an attacker. Powerful electromagnetic devices - the so-called grabers - can read information from chips at a distance of several meters. Thus, the fraudster easily gains access to the account and money of the reckless cardholder.
Protection of contactless cards
Recently, there are more and more developments and technologies designed to protect RFID data, for example, with various encryption methods. But if the fraudster manages to get the data, albeit encrypted, he will sooner or later be able to decrypt it. Therefore, the best way to safeguard your funds is to prevent an attacker from even reading your payment and personal data.
For this, special accessories with shielding properties are used. Metallized materials do not allow radio waves to penetrate into the wallet or cardholder, which excludes the possibility of reading information from the chip of the contactless payment card.
The Optexx online store offers a wide range of specialized RFID-protected accessories: wallets, wallets, card cases and card holders. All funds are made using a unique foreign technology and are intended for use by a wide range of people - including employees of banking and government organizations, whose documents and cards may contain information of particular importance. The technology works on the basis of the Michael Faraday cage principle and has been consistently proving its effectiveness for over a century.
Features of RFID shielding technology
Optexx technology is a unique development based on the use of special materials - metallized film. In appearance, it somewhat resembles ordinary foil, but is completely different in structure and characteristics. The material is made from an alloy of several metals, due to which it has a radio frequency impermeability in a wide wavelength range. That is, it shields not only radio waves of the standard 13.56 MHz frequency used in payment terminals, but also other radio frequencies, which excludes information reading even when using high-power scanners and grabers.
Advantages of Optexx protection technology:
With wallets and wallets, you will not have any problems with protecting your information and funds, which is especially important when traveling abroad, because today there is a real boom in RFID protection hacks and theft of funds from contactless bank cards.
Choice of RFID protected accessories
In the assortment of our online store, you will find several groups of accessories that will help you protect your finances while traveling. All products are made in compliance with safety requirements and have the appropriate certification documents. A wide variety of designs and colors will allow you to easily match accessories to suit your personal preferences and clothing style.
So which one can you choose?

Advantages of Optexx protection technology:
- Shielding from a wide range of radio frequencies. Your card cannot be “robbed” even with the use of specialized equipment, which is often used by professional fraudsters.
- Compactness. The material is lightweight and practical, and therefore can be sewn into wallets and wallets without losing their visual appeal. The presence of Optexx tabs will not weigh down your wallet or turn it into a bulky and inconvenient accessory.
- Resistance to external influences. High performance material that resists mechanical stress and provides additional protection for cards and documents.
- Availability of materials. This protection technology is distinguished not only by its high reliability, but also by its availability, since it does not require the use of sophisticated electronic equipment, encryption algorithms.
With wallets and wallets, you will not have any problems with protecting your information and funds, which is especially important when traveling abroad, because today there is a real boom in RFID protection hacks and theft of funds from contactless bank cards.

- Travel wallets and wallets. Accessories of various sizes are on sale, which will allow you to make a choice taking into account the number of cards, money and documents. The presence of a large number of shielded internal compartments allows you to reliably protect cards and chipped documents from intruders, even when the wallet is open. Wallets and wallets are large enough to conveniently store and carry also passports and cash.
- Card holders for cards. If you are not preoccupied with the question of where to hide money on a trip, since you do not use cash, but prefer only cards, then pay attention to cardholders and covers. The main advantage of these accessories is their compactness. The presence of several internal compartments (each with separate shielding) allows the use of cardholders not only for storing credit cards, but also for some documents - passes, driver's license, etc.
- Covers for cards. It is an inexpensive and reliable solution to protect against data reading and theft of funds from a contactless card. If you have only 1-2 such cards, then you can easily use cases for them and store the cards in a regular wallet or purse. You can easily select and purchase your favorite travel products by placing an order on your own in the online store or by contacting our specialists at the specified phone number. And rest assured that your data and finances will be reliably protected on any trip.
