Hi Robert, thank you for your informative article.

I have just starting using a Samsung Galaxy Note 8 and would like to use a wireless charger with it.

Here in Sydney Australia, we pay for transport fares with what is called an Opal card, which I believe has an NFC tag in it (type unknown). I believe this because when I first attached it to the back of my previous phone (a Note 3) in a stick-on card holder and used it at my local railway station, the card reader thought I had 2 cards. Once I turned off NFC on the phone, the Opal card was detected correctly.

I am concerned that if I leave the card on the back of my phone and place it on a wireless charger, it may damage the card or the data on it. I know the phone will get warm because it is being charged and I am not concerned about that.

I am waiting for a response from Opal about this and a person at the Samsung store here was not aware of any problem. I have also seen a short demo on YouTube of someone seeing if an NFC tag loses data after having it placed between a phone and a wireless charger. It still worked fine but it was only between the 2 devices for a second or so each time.

Are you able to shed more light on this please?

Regards Michael

Have you done any experiments in regards to placing one tag over another? I’m in the process of receiving a few tags to play with, so if you haven’t, and I don’t find anything in my research, I may do some experiments myself.

actually I’m doing a project on that and yes there is risk that can happen with tags. Such as if a thief were to take a tag and slap his over the real one. A person could get their information stolen by being sent to a malicious website.

Sure, but only if you instruct me on how to use electricity without the use of electricity… that is in short what you are asking =P

Hi, interesting article. Could you tell me how we could get 2 NFC tags interact with each other. Snce they aren’t powered by any inside battery, how could they exchange any info, if possible?
Thank you for your help. Fab

Just another way to be tracked by Uncle Sam.

Pardon if I’m wrong, but I didn’t see any claims that sight the NFC’s potential flaws. the risk of allowing something that can be so readily available, easily programmed (and later, reprogrammed), in combination with it’s dynamic application possibilities must present obvious security concerns. Perhaps my limited understanding of the technology is to blame for my paranoia-, but I can’t help but feel that an alternate argument should have been provided focusing on reasons anyone might be against a wide release of cheap, tiny, embeddable devices that can communicate, trigger actions, store information, etc. In a catastrophized circumstance in which a user is either negligent or malicious, couldn’t NFC be a great danger to our privacy?

Seems that apple have very different approach to mobile payments. They strongly belive in ibeacon and bluetooth. Mobile payments are on the stage that you really dont know whats the standard in 2018.
