Strip cam a cam with no credit card

Theoretically, the stripe has to “see” a magnetic field of about 4000 gauss to erase it.Using our online magnet calculator (or the formulas found in our article on Surface Fields), we can estimate the field strength at various distances from this magnet.The strip is like a tiny series of magnets, which interacts with the dust.

K & J Magnetics states, Because of this, we additionally suggest layering cards, facing out, by placing those least likely to demagnetize (example: bank cards) on the inside and those most likely to demagnetize (example: hotel key) on the outside.Cards are safe-kept in an ultra-slim front pocket while the back reveals a magnetic clip.Our money clip wallets provide a safer distance between magnet and card allowing you to rest easy knowing your cards are safeguarded.The magnetic stripes on many credit, banking and other types of cards use a strip of magnetic material to store digital data.
