Apple finally introduced wireless charging on iPhone 8, 8 Plus, and iPhone X. Although they are late to implement it, the important thing is that they have done it, but later than the competition like Samsung that has been incorporating it for quite some time.
But, everything has its advantages and disadvantages, and wireless charging does not escape this. Although it is very convenient to leave our terminal on a platform and start charging this can have certain problems that are not entirely known and that can affect you directly when charging your terminal.
The main drawback can affect your credit card and any other card that has a magnetic strip. If you put it on top of the charging cradle with your iPhone it may end up demagnetising or damaging the chips in it and you will have to order another one. This also happens with other cards such as the one given to us in a hotel to open the door of the room or the passport.
And you can ask me , who leaves the credit card next to the iPhone charging? I’m sure that you yourselves or someone you know carries a case that also serves as a card holder because on the cover it has slots to put either our ID or credit cards so that we forget to take our wallet when we go out.
So if you put your iPhone X into a wireless charging dock with this case, for example, and the cards inside can go bad. You can find this information at Apple on this page. Specifically it says the following:
Wireless charging uses magnetic induction to charge the iPhone. Don’t place anything between your iPhone and the charger. Magnetic mounts and cases, or other objects between the iPhone and the charger can reduce performance, damage magnetic strips or RFID chips, such as those found on some credit cards, security badges, passports, or remote control keys. If your case contains any of these sensitive items, remove them before charging or make sure they are not between the back of your iPhone and the charger.
So if you use this kind of case or have put something in the back of a case, remember to take it out before you put it in a base to recharge. This can be applied to any terminal that uses this recharging technology, not just Apple devices.
