RFID Blocking for Wallets Explained

Credit Card
I introduced the RFID blocking option to our entire collection based on many requests for this functionality. Lots of customers choose this option, but others have noticed it and wondered what RFID is and whether they need a wallet to block it. I’m not going to try to convince you to get it, just explain what it is as best I can so you can decide. 
Here's a brief explanation and answers to the most common questions...


What Does RFID Stand For?

RF stands for Radio Frequency and ID is Identification. It’s basically a way of transmitting information over the air between objects. There are a wide variety of applications for the technology, but the main ones are paymentsidentification, and building access badges.
If you have a credit card with PayPass or something similar, then it has the capability to transmit its information if placed near one of these readers. The concern is that it’s easy to get small readers which can be used by someone to get close to you and “skim”(rfid skimming) the information from your card, without ever taking your wallet out of your pocket. In fact, many mobile devices can read this info.


RFID Protection: What You Need it For

More recently, personal information has also begun to be embedded into RFID-enabled IDs. Cards from Washington, Michigan, New York, Vermont, and Canada all contain RFID chips with personal information. I don’t know whether the information can be actually stolen this way (they should have encryption, etc.) but many people who have these cards would prefer to prevent the information from being able to be transferred.
Probably the most common use for RFID cards is for building access. It’s convenient and fairly secure to have employees badge in to buildings, elevators, and rooms. I’ve worked in places where you need to swipe your badge to go through every almost door! So it certainly is convenient to be able to badge through these doors without taking your badge out of your wallet… or even your wallet out of your pocket if it’s at the right height.


RFID Blocking Wallets & Card Sleeves: Do They Work?

The blocking in SlimFold RFID wallets blocks the frequencies typically found in paymentidentification, and transit cards (13.56 MHz and above). It only blocks the building access cards if they also works on these same frequencies. Most people seem to want to block their payment cards through their wallets while still using building access cards- and that’s usually the case.
And if your building access cards are blocked, the RFID inserts in the MICRO can actually be removed and put back in. That lets you add RFID protection if you go on a trip or something. (The RFID blocking material in the Original models are sewn in, however.) 
Your other alternative is to get a non-RFID blocking wallet and then use the RFID card sleeves to protect just the cards that have chips.
So do you need RFID? The actual risk is probably not that high… and it of course depends on a lot of things like the risk factors of where you live and the cards you have. But I hope this helps clear up what the blocking feature is to help you decide. Feel free to reach out with any questions!


Does it make the wallet thicker or heaver?
Nope! Unlike some wallets that include bulky or heavy material, I use a patented alloy/Tyvek laminate. This results in the Tyvek models being the thinnest RFID blocking wallets in the world.
Will my building access badge work through it?
Probably but it depends on the frequency it uses. I’ve been finding that it tends to attenuate the signal of building access cards, making you need to get a bit closer to use them, but that it still works. Meanwhile, it will block payment, ID, and transit cards. If that’s a deal breaker, you can order both versions and then send back one of them.
Is the protection removable?
For the MICRO, yes. For the Original, no.
Will my train/bus pass work through it?
Probably not. Some folks have experimented with the placement of the card by putting it between the RFID blocking material and the outer layer of the wallet, but I haven’t heard definitive results about that yet. If you try it, please let me know how it works for you!

Loving my Cubic MICRO

Some of you may remember this post where I described the design process of creating the Cubic Tyvek MICRO. I had been using a Soft Shell for the last 6 months or so to test longevity, but after no signs of wear and a new Cubic sitting on the table from a photo shoot, I couldn’t resist switching over to it.
I’ve obviously used each of my wallets for extended periods during development and testing... and while I don’t have kids, I can imagine that picking between my models would be like asking someone to say which child they love the most. Each time I start using one, I find that I love it even more. And the Cubic is no exception. 
As it turns out, it’s been rising in popularity as well and is now the second best seller after the black models.
I’d love to see your Cubics in action as well so post them on Facebook, Twitter, or Instagram and I’ll look forward to seeing them!

Announcing Black Cubic

I’ve had this idea on the drawing board for awhile but it took close to a year to bring it to life. When printing on Tyvek, it’s really hard to get an accurate idea of what it’s going to look like when it actually comes off the press. This is because the traditional paper printing methods for achieving the look you want can’t be used:

For color, Pantone books provide a systematic way of getting the one you want. There are books for matte paper, glossy paper, and different inks such as metallic. But colors are shifted quite a bit when printing on Tyvek.
Before going into a full production press run, a proof would usually be done on the same material using color profiles to match the color output of the actual press that will be used. But these pre-press proofing printers can’t print on Tyvek. 
Screens are a method of making certain areas of a print come out lighter. They are measured in percentages and can usually be accurately represented on a computer monitor (soft-proofing) or at least on a hard proof, but how ink will behave on Tyvek is very unpredictable.
Solution: In order to get this cube pattern just right, I actually did a test proof during a previous print run I did on black Tyvek. I used a little patch on the side of the press sheet to see what a few different patters would look like, and also varied the screen amounts to get just the right balance of contrast without it appearing muddy at all.
Then during the actual production run, the metal printing plate still had to be re-made three times to fine-tune the output.
In person, they’re playful and clean yet somehow sophisticated. I’m very pleased with how they came out and am excited to finally be sharing them with you. Enjoy!
