Phones do create a magnetic field, but thankfully, it isn't strong enough to demagnetize credit or debit cards. The small magnet in the phone's speaker is the main culprit of generatingthe magnetic field. This field, however, is too weak to cause sufficient damage to a credit card magnetic strip, with some exceptions.
Magnetic Fields From Your Phone
While your phone does create a magnetic field, it isn't strong enough to demagnetize your credit cards. The magnetic field comes from a small magnet located at your phone's speaker. This is too weak to cause any immediate damage to your credit card.
Yes, your phone does produce a magnetic field, but it's nowhere near strong enough to damage or deteriorate your bank card. The magnet in your phone is found in the speaker, which is much too weak to harm your cards. Therefore, there's nothing to worry about carrying your bank cards and phone together.
“Don't place credit cards, security badges, passports, or key fobs between your iPhone and MagSafe Charger, because this might damage magnetic strips or RFID chips in those items,” Apple said.
Scratches and general wear are common causes of demagnetization, but prolonged exposure to magnets can also ruin a card's magnetic strip. Fortunately, you don't need to worry about magnetic damage if your credit card has an EMV chip.
If you find the magnetic stripe on your credit card is no longer working, it may have become demagnetized.
A credit or debit card can also get demagnetized if the strip gets extremely scratched. Try storing your card in a safe place, like a wallet (away from the clasp or other metal parts, of course). It's best to store your card in a soft, cushioned place away from spare change or other rough objects.

You can save your personal information or credit card number on your iPhone to speed up filling in online forms and making purchases. Go to Settings > Safari > AutoFill.
Though there are more magnets in the iPhone 12/13/14 models, Apple says that they are "not expected to pose a greater risk of magnetic interference to medical devices than prior iPhone models."
Cards feature an identifying magnetic stripe, and information can be stolen from it rather easily if criminals tamper with a card reader by adding a skimmer. A digital wallet — such as Apple Pay — is even more secure than a chip card because it doesn't use your actual card number for the transaction.
Credit Cards:
Magnets can erase the data on a magnetic stripe, rendering the card useless. The strength of the magnet required to damage a card depends on the card's magnetic stripe technology. EMV chip cards are not susceptible to magnet damage.
A section card is what the staff uses to get into rooms and other “Employee Only” sections of the hotel. On a magnetic stripe machine, these are the same type of cards issued to guests. Normally a cellphone or magnet on a purse will not demagnetize the room key.
You may have heard that a magnet can 'demagnetize' a credit card's magstripe. This is not generally true. The magnetic stripe on a credit card is made from a ferromagnetic material—that is, a material that independently retains its magnetic properties.
Does MagSafe Cardholder affect credit cards? If you're worried about whether having magnets in your wallet may affect your debit and credit cards, worry no longer. Not only does Apple ensure that MagSafe products cannot interfere with magnets, but there are also fewer and fewer magnets involved in credit cards.
Magnetic Stripe Keys
When the guest inserts the card into the lock, the card reader reads the information on the magnetic stripe and verifies that the guest has access to the room. One common myth about magnetic stripe keys is that they can be deactivated by cell phones. However, this is not true.
The Wallet app lives on your iPhone. It's where you securely keep your eligible credit and debit cards, loyalty cards, boarding passes, tickets, car keys and more — all in one place. And it all works with iPhone or Apple Watch, so you can take less with you but always bring more.
However, if someone gets hold of your phone, they can access all of the stored financial information you have. So it's always advisable to have a PIN or password lock on your phone and to use biometric verification, such as face recognition or fingerprint scanning, to ensure extra security.
Yes, you can put your credit card on your phone, by using a mobile wallet like Google Pay, Samsung Pay, and Apple Pay. Mobile wallets securely store your payment information and passwords. These applications allow you to pay when you're shopping using your device so that you don't need to carry your cards around.
According to Apple's site, "the leather wallet is shielded so it's safe for credit cards." That shield protects both Low Coercivity (LoCo) and High Coercivity (HiCo) cards — which is a fancy way of saying how resistant something is from being demagnetized.
As the Wireless Charging Pad uses an electromagnetic field, it is possible for this to damage any bank cards or any other magnetic cards. If you are using a wallet case with a magnetic card inside the case, please ensure that any magnetic cards have been removed from the case to avoid any damage to your magnetic cards.
The biggest takeaway is that both the iPhone 14 Plus and 14 Pro Max were severely cracked or shattered after the first drop, where the iPhones 12 and 13 proved to be some of Apple's most durable phones and didn't have severe damage until the second or third drop.
Yes, if you have a contactless card with an RFID chip, the data can be read from it.
Although banks claim that RFID chips on cards are encrypted to protect information, it's been proven that scanners—either homemade or easily bought—can swipe the cardholder's name and number. (A cell-phone-sized RFID reader powered at 30 dBm (decibels per milliwatt) can pick up card information from 10 feet away.
If you're at low risk, or simply don't use anything that has RFID in it, then you probably don't need RFID protection. For low-risk people that still have cards, passports, or ID you'd prefer to keep under wraps, then investing in some protection could be worth that extra peace of mind to know you're covered.
