About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

PURISTO
RFID blocker card

The RFID blocker from PURISTO offers comprehensive 360° RFID & NFC protection for all cards in the wallet. It effectively protects against data theft by creating an invisible protective field around the cards without the need for additional sleeves. With a thickness of just 0.8 mm, the card is extremely thin and fits easily into any wallet. Another advantage is the integrated Lost & Found service, which guarantees secure return in the event of loss. The card is made of 75 per cent recycled PET, which not only offers tested security but is also environmentally friendly.

  • 360° RFID & NFC protection
  • Ultra-thin design
  • Integrated Lost & Found Service
  • Medium price segment

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

As part of our practical test of the RFID Blocker card from PURISTO , we were able to comprehensively verify the manufacturer’s advertising promises. A functional test with RFID-enabled cards showed that none of the cards tested could be read as long as the blocker card was present. This shows that the product actually works. In addition, the signal blocking test at various angles showed that the card could not be read at any angle, which indicates perfect signal blocking. The moisture test also confirmed the quality: after exposure to water, the blocker card worked flawlessly and retained its blocking ability. The range test showed that the RFID card could not be successfully read at any of the tested distances under the influence of the Blocker card, indicating that all signals were completely blocked. Finally, the blocker card proved to be versatile and worked in all wallet types tested without any restrictions. Overall, the PURISTO RFID Blocker card fulfils all expectations and offers reliable protection against data theft.

At the time of testing, the product had not been listed on Amazon for long enough. Therefore, the existing reviews do not sufficiently reflect the advantages and disadvantages of the product, so this point is neglected in the evaluation.

Prices of up to €5.99 are charged on the Internet for equivalent products. Very cheap products are available from as little as €2.99 . The RFID blocker from PURISTO is therefore currently in the middle price segment with a price of €4.99. For the quality and performance received, the price-performance ratio is very good.
