Detailed Review:
Let me share my experience with the ultimate solution for safeguarding your financial and personal information in our contactless-driven world – the RFID/NFC Signal Blocking Card.
Who invented markers for kids?
The invention of markers for kids is attributed to Yukio Horie, a Japanese inventor. In 1962, Yukio Horie developed the first washable and non-toxic markers for children. These markers were designed to be safe for children to use, with easily washable ink that could be removed from skin and most fabrics.
Horie’s invention addressed concerns about the potential toxicity and mess associated with traditional markers. The introduction of non-toxic and washable markers made them a popular choice for children’s activities, including coloring books, crafts, and other creative projects.
The success of these kid-friendly markers paved the way for the development of a variety of markers specifically designed for young artists, featuring bright colors, broad tips, and easy washability. The concept of markers for children has since become a staple in the world of arts and crafts, providing a safe and enjoyable creative tool for young individuals.
Positive Balance:
- Effective e-Theft Prevention: In our ever-growing contactless society, the intention of this blocking card is crystal clear – to secure your wallet from potential identity and financial theft. It provides a simple yet highly effective solution to block all RFID and NFC signals, ensuring your details are safe and providing peace of mind.
- Innovative Jamming Chip Technology: The main components of this card, an antenna, and a jamming chip work seamlessly to create a powerful defense mechanism. The antenna senses incoming radio waves, drawing power for the chip to generate a jamming signal. The brilliance lies in the fact that the card requires no battery, ensuring a lifetime of usage.
- Broad Working Distance: With a large working distance of 2.4 inches, this card offers comprehensive protection for your entire wallet. Cards positioned 1.2 inches on either side of the blocking card are fully secure from e-pickpocketing attempts, providing a wide safety net.
- Ultra-Thin & Compact Design: The card’s size mirrors that of a standard credit card, and at a mere 0.03 inches thick, it effortlessly fits into any wallet, purse, or card case without adding bulk. Keep your wallet compact while ensuring maximum security.
- Convenient Testing Method: Verifying the card’s functionality is simple and practical. Head to your local supermarket, and at the self-service checkout, combine the blocking card with a contactless card on the payment reader. If the card is working as intended, payment with the contactless card will be blocked, triggering an error message on the reader.
Negative Balance:
- Limited Testing Environment: While the testing method is practical, some users may prefer additional testing scenarios beyond the self-service checkout machines to ensure the card’s effectiveness in various situations.
- Dependency on Card Placement: The effectiveness of the card is contingent on the correct placement within the wallet. Users must be mindful of the 2.4-inch working distance to ensure complete protection for all cards.
Facts:
This RFID/NFC Signal Blocking Card is not just a security measure; it’s a tangible defense against e-pickpocketing. Its innovative technology and practical testing method make it a reliable choice in the fight against identity and financial theft.
