Questions & Answers

How big is it? Is it possible to completely conceal the cards?

Hi - it's 2. 2" wide by 3" tall 0 inches in height As shown in the image, it does not completely cover the cards to aid access, but you can rest assured that the card numbers are completely or nearly completely covered (depending on the card type). The previous four years have been The fact that the last five digits are visible poses no threat to security - These are the same digits that credit card companies use to publicly identify your accounts, and they're useless without the full card number and code on the back of the card. br>I'd be happy to answer any other questions you may have!

Is there a limit to how many times you can use the CardNinja?

I took it off my phone case and put it on another, and it worked fine; however, I wouldn't leave it off all the time. The adhesive will eventually wear off.

This is something I'd like to get as a stocking stuffer. What is the appearance of the packaging?

It's actually quite nice; I couldn't find a picture of it, but it resembles an Apple package in appearance - There are some shiny/silver areas on the surface. When I get home, I'll try to snap a picture. It looks like a gift (I received mine as a gift).

How many cards do you think will fit?

When I didn't want to carry my wallet, I had the most in it: ten dollars. There are a total of 12 cards in this deck, plus cash that has been folded. It could still carry fewer cards after that, and nothing fell out!

This credit card holder is absolutely fantastic! I intended to postpone my writing for a while
5/5

This credit card holder is absolutely fantastic! I wanted to give this item some time to see how it performed before writing a review. It's been seven months since I've had it, and it's in perfect condition. I regularly fill this thing up, and I use it with up to six cards every day, and the holder has never ripped or become too loose to hold all of my cards. My cards only fall out when I drop my phone on the ground, which is entirely my fault because the cloth is so stretchy and snugly holds your cards. I haven't been lugging around a purse or bag when I shop since I started using this because the adhesive on the back is extremely sticky, and it doesn't even peel on the corners over time; I haven't been lugging around a purse or bag since I started using this, and it feels so liberating! Everything I need (cards, cash, IDs, and so on) can be stored on the back of my phone. This is ideal for anyone who is tired of carrying a bag or purse around with them all the time and only needs it for credit cards and cash. The bulky feeling on the back of your phone when your card(s) stack up in it is the only thing you have to get used to when using it, but I carry six cards on a daily basis and my phone still fits comfortably in my jeans pocket. The quality is excellent, it is dependable and secure, it eliminates the need to carry a bag, and it is incredibly easy to set up.

For the past year, I've been using Cardninja and I love it! For the function, I give it 5/5 stars
3/5

For the past year, I've been using Cardninja and I love it! For the function and excellent quality, I give it 5/5 stars. I had no problems removing it from my old phone and reattaching it to my new one; just peel slowly and the majority of the adhesive will remain on the cardninja. br>br>I deducted two stars because this advertised product has NO RFID BLOCKING, and it is identical to the NON RFID product - There isn't a single "metal plate" to be found anywhere! I went back and reordered, only to be sent the same one! br>br>Saving money by getting the CLASSIC instead of the RFID-blocking cardninja.

It's the best thing I've ever discovered! I was on the lookout for a minimalist wallet and searched YouTube and Amazon for the latest trend
5/5

br>br>I came across some phone wallet cases- br>Too bulky, poorly designed, but very fashionable. . . br>I discovered minimalist wallets- br>I was on the verge of purchasing a $70 rubber band and two plastic pieces. . . . . . (The Ridge Wallet) Asset)br>br>There are also two pieces of leather sewn together with one card access on the outside, but it also holds movie passes if you need one. . . . (The Trihold)br>br>Is it true that one comes with more tools than a Swiss Army knife and has space for two cards and cash, as well as a corset feature? (Trayvax Wallet)br>br>Finally, a piece of super aluminum that holds 4, 6, 8, 12 cards, no more, no less, and no cash. . . (Decadent Minimalist)br>br>After that, I saw a friend with a hard plastic version of this with some company logo on it. He liked it, but said it was too stiff and didn't "hug" the cards; instead, they were stuffed into it like a file or container. When inverted (with no shaking), cards would fall out. This was discovered! br>br> br>Let's go back to YouTube and look at this wallet again. The neoprene is what sets this apart from all other adhesive phone wallets. I carry six credit cards and $20 in multiple bills folded into quarters at all times. The best part is when I don't have to carry as many cards or spend as much money. Neoprene conforms to the shape of the body. Yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes When inverted and shook beyond oblivion, or slam the phones edge against your hand, the cards will come out regardless of neoprene tension. With the same unrealistic shaking and manic behavior as a traditional or trendy minimalist wallet. br>br>Simply rotating it, tossing it on the counter, dropping it between the car seats, or putting it in your pocket upside down will not release anything! br>br>THE ONLY CONTRARY TO GETTING YOUR CARD OUT is that you must pull all of them partially out, thumb through them until you find the one you want (neoprene allows for sifting/sorting), and then push them all back in. I don't see how the manufacturer could correct or adjust this, but it's worth noting. After a month-long period-long period-long period-long period-long period- long period-long period-long period-long period-long period- br>br>I put it to the test to see how flexible it was. I took all of my credit cards and cash out of the house and left for the night. It reverted to its original size, which snugly held one card. br>br>Durability is satisfactory. The small logo is starting to fade/wear off, but that's okay. Due to a battle with Velcro, the material has burred or scuffed. The CardNinja has no holes, tears, folds, or loss of adhesion or function. br>br>When this one wears out, I'll buy another one! That's not going to happen anytime soon, in my opinion.

This is a great idea
5/5

I was just about to put a metal plate from my magnetic holder into my old Ninja wallet when I realized what had happened. It was successful. Yes, it was inconvenient because it kept falling out. The metal plate is sewn into the outer fabric, making this an ideal solution. Other brands I've tried have all been a waste of time. After several years of use, CardNinja has yet to let me down. I live in Texas (think ridiculously hot desert) and carry a phone with me at all times. I haven't misplaced a card yet, and my wallet stays put even in 115 degree weather. The vent magnet, on the other hand, is a bit of a mystery. mehh. It holds my S8 well enough with a case and four cards, but I prefer to use a larger magnet mount. My vehicles' angles and positions are primarily to blame.

I always carry my driver's license, gun license, debit card, and occasionally a few bills folded over twice in it, and it has never failed to keep my cards in place
5/5

I've had it for at least six months, if not more than a year. I've moved it from one phone to another, then taken it off again to put it on a new case. It still sticks fine, though I had to apply some pressure to the corner that I initially pulled up in order for it to straighten out and lay down again. br>I'm planning on buying another one soon in case I need to transfer it and it doesn't stick. Even if it doesn't stick a fourth time, I'm surprised it ever stuck a second or third time; I'm not sure it was designed to transfer in the first place. br>This amazing product has exceeded my expectations.
