Neodymium magnets can affect pacemakers.
The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and other implanted medical devices. Many of these devices are made with a feature that deactivates it with a magnetic field. Therefore, care must be taken to avoid inadvertently deactivating such devices.
Can credit cards be damaged by magnets? Short Answer is No, not with our product.
The magnetic strip on credit cards come in two varieties. The high-coercivity ones, like a typical credit card, require a field strength of somewhere around 4,000 gauss to demagnetize. The low-coercivity ones that are often re-written, like hotel keys or gift cards, require about 300 gauss.
The magnets we use in our wallets have a field strength of around 1,500 gauss which is further diminished by the leather thickness. However, after testing the wallet for 6 months, none of the credit cards and debit cards were demagnetized, but Hotel Key Cards and Garage Tickets were demagnetized when kept in the wallet.
