In the picture, the vertical lines of the middle stripe (Track 2) are especially obvious, since they are more widely spaced than tracks 1 & 3. If you rub a neodymium magnet directly across the magnetic stripe, with the magnet touching the card, the data is likely to be erased or scrambled.To test this, we move a magnet near the credit card at various distances.In the video below, we controlled this magnet-to-card distance by stacking some paper of known thickness on top of the card. While thinner magnet shapes exhibit weaker magnetic fields, the magnetic fields are usually stronger out at the edges.Magnetic stripes were originally invented in 1960 by IBM to make purchasing with credit cards faster and allow greater use of computers during the process.

The growing use of cards by banks, airlines and stores required a faster data entry method than rubbing carbon paper over embossed numbers!

Bank cards, employee cards, library cards tend to be constructed with a high-coversity magnetic strip – a stronger and more durable option for long-term use.
