MagSpoof is a device that can spoof/emulate any magnetic stripe or credit card. It can work “wirelessly”, even on standard magstripe/credit card readers, by generating a strong electromagnetic field that emulates a traditional magnetic stripe card.
Note: MagSpoof does not enable you to use credit cards that you are not legally authorized to use. The Chip-and-PIN and Amex information is not implemented and using MagSpoof requires you to have/own the magstripes that you wish to emulate. Simply having a credit card number and expiration is not enough to perform transactions. MagSpoof does allow you to perform research in other areas of magstripes, microcontrollers, and electromagnetism, as well as learn about and create your own devices similar to other existing, commercial technologies such as Samsung MST and Coin.
MagSpoof can be used as a traditional credit card and simply store all of your credit cards (and with modification, can technically disable chip requirements) in various impressive and exciting form factors, or can be used for security research in any area that would traditionally require a magstripe, such as readers for credit cards, drivers licenses, hotel room keys, automated parking lot tickets, etc.
