To be completely honest we were sceptical at first about adding RFID blocking to our wallets. Having minimalism at the core of our brand, we were hesitant to add something to our wallets only for commercial purposes and that might not have any use at all.What made us decide to add RFID blocking?Around a year after launching the original DUN wallet we had received a significant amount of requests from our customers to add RFID protection. So we started to investigate the issue of so called ‘digital skimming’ a bit deeper. We found articles like this, which explained how ‘digital pickpocketing’ actually works. Around that time, in the middle of a wide adoption of contactless (credit)cards, it suddenly didn’t seem such a bad idea to have RFID blocking as a prevention measure.How digital skimming worksRFID enabled cards – or so called contactless cards – can be recognized by a symbol that looks like a wifi symbol turned on its side. These cards transmit a radio wave when in close proximity of a reader (or contactless terminal). Data is transmitted from the card to the terminal. The bank identifies the card as one of its own and approves the client’s transaction and closes a hand shake deal with the point of sale terminal almost instantly.Digital pickpocketingNow anyone with such a wireless point of sale terminal can simply walk into a crowded place (like the London tube) and start holding the terminal close to bags/pockets. The convenience of not needing to enter a PIN code for contactless transactions under €25, makes stealing this amount by a ‘digital pickpocketer’ done without any obstacles.Digital identity theftThere is another way how the date that’s transmitted by your RFID cards can be stolen and it’s called digital identity theft: The data can be picket up by a reader or even with an app on a smart phone. Your cards data is uploaded to a magnetic credit card creator – a machine that can be bought for a couple hundred dollars – and a copy of your card can be created.Finally, the DUN RFID leather wallet: Black Edition.Once we decided to add RFID protection we wanted to be sure that it was effective, so we chose a high quality German made foil. After testing a 99.9% effectiveness on multiple of our samples they provided us with a certificate to back it up the claim.Around the same time I stumbled upon a beautiful matte black calf leather. For DUN wallet’s anniversary we created a special ‘Black on Black’ design using this new leather in combination with a gun metal clip; the DUN Black Edition. Of course we took the opportunity to apply the RFID foil on the inside. The end result our new RFID leather wallet was amazing.The micro thin layer of foil is completely hidden under the wallets lining and even added that little extra reinforcement to the wallet that made the DUN Black Edition feel even more premium in combination with the new calf leather. The Black Edition ultimately felt like the successful evolution of the DUN wallets design and was here to stay.Commercially it also proved to be a success with just months after releasing the Black Edition, it became our best selling wallet. We decided to use the same leather for all our products and add RFID protection as standard on our latest DUN Fold.
