Car key signal blocker case Faraday cage fob key bag RFID locking bag in black or brown, 13.5 x 9.5 cm microfiber pouch for blocking mobile phone signals and protecting bank cards from scanning or degaussing
Microfiber RFID and Signal Blocker Bag for Phones and Cards in 13.5 x 9.5 cm

This unisex signal-blocking pouch provides a straightforward solution for managing digital connectivity and security. Crafted from plain microfiber, it measures 13.5 cm by 9.5 cm and is offered in black or brown. It is designed to shield the items you carry daily—such as smart phones, bank cards, and disk readers—from unwanted signal transmission and scanning. By placing devices inside, it blocks mobile phone signals to prevent radiation and can protect confidential magnetic card information from being leaked, offering practical control in both personal and professional scenarios where uninterrupted time or data security is needed.
Features and Construction

This pouch combines specific materials and a precise size to deliver its core functions. Its construction is focused on creating a barrier against electromagnetic signals for everyday carry items.
Material and Build
The bag is constructed from a microfiber fabric, resulting in a soft and flexible pouch. This material choice provides the physical structure needed to house devices while incorporating the barrier layer mentioned in the source. The design is plain in pattern and intended for unisex use, making it a neutral accessory suitable for various users. The build is centred on functionality for carrying daily electronic items.
Size and Practical Fit
The pouch has defined external dimensions of 13.5 cm in width by 9.5 cm in height. This size is compact enough for easy portability while being sufficiently spacious to accommodate common items like mobile phones and card holders. The scope of application explicitly includes smart phones, bank cards, and disk readers, indicating the intended fit for these objects. The measurements provide a clear expectation of what the pouch can hold.
Uses and Placement

The pouch addresses specific scenarios where signal management or data protection is beneficial. Its use is supported by the practical functions described in the source material.
Event or Professional Use
For individuals such as managers or those in business and public relations, the bag offers a way to secure leisure time without fully disconnecting. By placing a mobile phone inside, incoming calls receive a 'temporarily unavailable' message, avoiding misunderstandings that can arise from simply switching the phone off. This allows for uninterrupted focus during meetings, family time, or other engagements while maintaining a professional appearance, as the phone remains on but unreachable.
Everyday Home Use
In daily life, the pouch serves as a protective case for sensitive items. It can be used to shield bank cards, credit cards, or ID cards from RFID skimming attempts when carried in a bag or pocket, helping to prevent financial data theft. The anti-radiation property is noted as being favoured by pregnant women to limit mobile phone signal exposure. It provides a simple method for organising and protecting everyday carry electronics within the home or while out.
Benefits and Buying Value

The value of this product lies in its specific, source-supported functionalities that address modern concerns around connectivity and privacy.
Reuse and Low Maintenance
As a durable fabric pouch, it is designed for repeated use. The microfiber material suggests it can be wiped clean if needed. There are no complex care instructions required; its maintenance involves simply using it as intended—placing items inside and removing them. This reusability offers ongoing value compared to single-use alternatives, providing continuous protection for your devices and cards whenever needed.
Why Choose This Product
This product provides a tangible solution backed by clear specifications. It offers a measured 13.5 x 9.5 cm size, a choice of black or brown colour, and a stated ability to block mobile phone signals and shield magnetic cards. The value comes from having a dedicated, portable tool that addresses specific scenarios of signal blocking and RFID protection, supported by its described features.
