G+_George Kozi Posted October 15, 2017 Share Posted October 15, 2017 Originally shared by George Kozi I don't care how "fancy" a design is, or if it is made by some frou-frou brand, in this day and age, if a wallet doesen't have RFID/NFC blocking, it's not worth ANYTHING . You should take a look at the wallet you are carrying around. All the cards these days NEED protection. I ordered one of these on Amazon yesterday. It costs 11.99 € . Leather, RFID blocking, and the "accordion" design is something I like. It gives easy access to the cards without having to fütz around with shoving them into slots.

G+_Cory Albrecht Posted October 15, 2017 Share Posted October 15, 2017 Ponder for a moment, just how hard it would be to scan your NFC-chipped card in you wallet in your pocket. A regular scanner would have have to be within a centimetre of your card to be able to work so that means the person using the device would literally need to be breathing down your neck because the chips response is so weak. Because the chip in your card transmits omnidirectionally, the strength of the signal falls exponentially relative to (4?R)², so at 1m away the signal is 157 times less and would require a visible antenna array. At 2m away the signal strength would be 631 times fainter, requiring even a bigger array. Link to comment Share on other sites More sharing options...
G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 well, they only need to figure it out once... In a crowded place somewhere. I'd rather have shielding around my bank cards. Link to comment Share on other sites More sharing options...
G+_Luis Mendez Posted October 15, 2017 Share Posted October 15, 2017 Plus let's say they go through so that trouble, the bank will just refund you right away, it probably stop the purchase in the first place and cancel the card. Link to comment Share on other sites More sharing options...
G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 So are you guys saying that NFC/RFID shielding is unnecessary? Link to comment Share on other sites More sharing options...
G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 Fr. Robert Ballecer, SJ Could you and if he is not too busy Steve Gibson weigh in on this? It would be useful to clarify. Link to comment Share on other sites More sharing options...
G+_Luis Mendez Posted October 15, 2017 Share Posted October 15, 2017 I wouldn't go out of my way to look for, or not buy a wallet because it's missing it. I'm also a front pocket wallet user and only carry one card at a time. Seems pointless to me, tinfoil hat type of thing, no? Link to comment Share on other sites More sharing options...

G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 By the way... if you lift a shirt from a store and try to walk out with it, the alarm will sound, even if those antena/gates are a meter or so away from you. What would stop a determined gang from rigging one of those up to read the cards in your wallet? It's a bigass antena and it could be made to look like anything.... even put it under the ice cream vendor's cart orin a doorpost at the airport... leave it there to do it's work for a month or so...

G+_Rud Dog Posted October 15, 2017 Share Posted October 15, 2017 George Kozi, she looks a bit thick for pocket storage. If you have received your wallet can you expand on the comfort if placed in the back pocket of a pair of jeans? Link to comment Share on other sites More sharing options...
G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 It'll arrive in after the weekend. I'll tell you. The description sais 2 centimeters thick... and it has 12 compartments. Link to comment Share on other sites More sharing options...
G+_George Kozi Posted October 15, 2017 Author Share Posted October 15, 2017 I'm using NFC every day in every store around here (The Netherlands). Everybody has the gear deployed, from the local supermarket to the green grocer, to the asian store on the corner etc. It's ubiquitous. It has been so for like two years. All I do is wave my card on the side of ot above the terminal. The machine goes "beep" within a second and I payed. Link to comment Share on other sites More sharing options...
G+_Luis Mendez Posted October 15, 2017 Share Posted October 15, 2017 Hey man, use whatever you need to use to ease you fears of being robbed. But the sentiment of "because it's not rfid/nfc blocking it's not worth it at all" is not popular, most people don't care. Our money is insured. The bank will replace it 100%. It's a minor inconvenience if any. Link to comment Share on other sites More sharing options...
G+_Cory Albrecht Posted October 15, 2017 Share Posted October 15, 2017 George Kozi The would also need to know the encryption keys for the data on the chip, too. The chips return an error if you don't send the right one in the request to get the data. Link to comment Share on other sites More sharing options...
G+_Cory Albrecht Posted October 15, 2017 Share Posted October 15, 2017 George Kozi Those RFID tags for merchandise are very different from NFC chips. They are designed to output far more power back when pinged which is why they can be read 1m away. And those antenna arrays are huge aren't they? From the floor to your waist and as wide as you are to pick up that more powerful response response. And the antennae on those tags are also several times the size of the ones on your chip-card to enable that more powerful return. Link to comment Share on other sites More sharing options...
G+_Cory Albrecht Posted October 15, 2017 Share Posted October 15, 2017 Try leaving your chip card in your normal wallet and scan it that way, does it work? Maybe, maybe not. In my leather wallet it works maybe half the time if and only if the card is in an outside pocket with only one layer of leather. If it's in an inside pocket and my wallet is folded shut there are several layers of leather or cloth and a few other cards in the way, it never works. How close do you think somebody can get to your back pocket where you wallet is with reader 4 or 5 times the size of those counter-top readers in the stores?

G+_Nathan Weber Posted October 17, 2017 Share Posted October 17, 2017 Why would they bother getting into your wallet? They'll just hack your bank. That's where the money is, after all. Link to comment Share on other sites More sharing options...
