Before we kick off, let’s have a quick look at RFID technology and how it functions.
What is RFID?
RFID means Radio-frequency identification. It is a technology that integrates the use of electromagnetic or electrostatic spectrum to unambiguously identify an object, animal or person. Today they are encountered in ID Cards, passport and credit cards as wafer thin chips to help accelerate transactions. They store and transmit your account information and personal details. Handheld scanners can read these chips through wallets and clothing up to several feet away. Currently issued credit cards, passports, and other IDs have embedded RFID chips.
How RFID does affect our lives
RFID is very crucial in our daily lives, because it is a tremendous technology for businesses, warehousing, retail and livestock. RFID tags can be bonded to merchandise in a warehouse so that employees can automatically carry on inventories with handheld readers that send out data to the company's servers or databases. Users don't have to go back to a terminal to enter data manually. For example, going to the grocery, filling up your cart and walking through the door. No longer will you wait as someone calls up each item in your cart one at a time. Rather, these RFID tags will communicate with an electronic reader that will observe every item in the cart and calls each up almost immediately. The reader will be linked to a large network that will send data on your products to the retailer and product manufacturers. Your bank will then be given notice and the amount of the bill will be subtracted from your account. There will be No lines, and waiting.
Why do you need RFID-Blocking products?
RFID Blocking is a kind of passive shielding of RFID Signals through either a metallic encased wallet or RFID blocking sleeve like what you see in the market today. RFID-blocking products like RFID-blocking wallets are designed and projected to help isolate you from a very particular brand of electronic pickpocketing, called RFID skimming. The concern is that some credit cards, passports, and driver's licenses now come with engrafted radio frequency identification chips. But do you actually need RFID-blocking products? Perhaps, perhaps not. If your credit cards don’t come with RFID chips, then obviously you don’t need one. And even if you do have RFID-chipped cards, the chance of being maliciously scanned is extremely low. On the other hand, the possibility is there and the chance is non-zero.
How RFID-Blocking products do works
RFID chips work by using radio waves to communicate. The object, such as a credit card, contains an RFID tag with data, and an RFID reader uses radio waves to read the data from a tag. RFID chips have very small electromagnetic fields, which is what makes them capable to read without having to start communications. What is required is proximity. That’s why; it is possible somebody could scan you through your pocket. And yes, people have been scanned like this. Luckily, radio waves are comparatively easy to disrupt and block, and that’s how RFID-blocking product works: they encase your credit cards in a material that interposes with radio waves. If the product is constructed in the right manner to be a Faraday cage, it will stop all electromagnetic fields and prevent communication between your cards and RFID scanners.

Samsung confirmed that the Galaxy S8 would be formally unveiled at a dedicated launch event in New York on March 29, 2017. This device is expected to be one of the best devices the Korean tech giant has ever made and is rumored to include a new curved screen, super-fast processor and improved camera.
So what can you expect from the Galaxy S8? Based on the rumors and leaks surrounding the device, look for two models — a 5.8-inch phone and a giant 6.2-inch S8 Plus. You can also anticipate a built-in digital assistant named Bixby and a display that takes up most of the phone's front.
Samsung Galaxy S8 Specs:What's New?
The most notable change is that we’re expecting a bump in screen sizes. Apparently, the two new Galaxy handsets will feature larger 5.8-inch and 6.2-inch displays, up from 5.1-inches and 5.7-inches on the old phones. But importantly, the new ‘Infinity Display’ aesthetic means we’re expecting that the rough body dimensions of the phones will stay the same as before. A higher resolution panel is also tipped – specifically, 2,960 x 1,440 pixels compared to 2,560 x 1,440, creating an 18:9(-ish) aspect ratio.
It’s also likely that the Samsung Galaxy S8 will be available with different processors in different markets, as has been the case previously. Some units will almost certainly feature Samsung’s custom-built Exynos 8895 chip, while others seem certain to use Qualcomm’s new Snapdragon 835 processor – which Samsung manufactures.
What’s important about both chips is that they’re built on a new 10nm FinFET manufacturing process. That means that the transistors can be more densely packed, offering more power (up to 27% improved performance) or better efficiency (up to 40% lower power consumption) compared to older 14nm chips.
Facial recognition and iris scanning
The Galaxy S8 may include a facial recognition feature -- in addition to a possible iris scanner and the usual fingerprint sensor, which may have migrated to the back of the device, according to a report by Korea Economic Daily. (Note that the forthcoming iPhone 8 is also rumored to supplementing its Touch ID technology with facial and/or iris recognition.)
A rainbow of options (plus gold)
Among a torrent of leaked photos and mockups appearing during the past week, TechDroider tweeted a picture that appears to be the front plate of the Galaxy S8 in a variety of colors including black, white, blue, gold, and silver. Another tweet included additional images of what appeared to be a Galaxy S8 and S8 Plus, powered on.
People have been concerned about RFID chips for many years now, and not just in the context of credit cards. All U.S. passports issued starting in 2006 have these chips that track your photo and information. Metro cards have RFID chips for quick swiping and dogs are implanted with RFID chips for safety tracking. They’re everywhere.
RFID chips work by using radio waves to communicate. The object, such as a credit card, contains an RFID tag with information, and an RFID reader uses radio waves to read the information from a tag. The key is that RFID chips have tiny electromagnetic fields, which is what makes them possible to read without having to “initiate” communications. All you need is proximity.
That’s why, in theory, somebody could scan you through your pocket. And yes, people in the real world have been scanned like this.
Fortunately, radio waves are relatively easy to interrupt and block, and that’s how an RFID-blocking wallet works: they encase your credit cards in a material that interferes with radio waves. Wallet RFID will block all electromagnetic fields and prevent communication between your cards and RFID scanners.

Other Ways to Stay Safe and Protected
Because RFID technology is insecure, we recommend that you avoid using it as a contactless payment method if at all possible, especially because better alternatives exist. For example, Android Pay and Apple Pay, which both use NFC technology instead, are both safer and more convenient.
