# samyk/magspoof

A portable device that can spoof/emulate any magnetic stripe, credit card or hotel card "wirelessly", even on standard magstripe (non-NFC/RFID) readers. It can disable Chip&PIN and predict AMEX card numbers with 100% accuracy.

## What it is
MagSpoof is a portable Arduino-based device that spoofs and emulates magnetic stripe cards (credit cards, hotel keys, etc.) wirelessly by generating an electromagnetic field, working even on standard non-NFC magstripe readers. It supports all three magstripe tracks and is designed for security research and personal card storage.

## Use cases
- emulate a magstripe credit card on a standard reader wirelessly
- store all my magstripe cards in one portable device
- security research on magstripe readers and electromagnetism
- build a device similar to Samsung MST or Coin
- test hotel key card and parking ticket readers
- learn about microcontrollers and magnetic stripe data encoding

## When to choose
- you need to emulate magnetic stripe cards on traditional readers for authorized research
- you want a DIY Arduino hardware project for magstripe security research
- you want to consolidate your own magstripes into a single device

## When to avoid
- you need NFC/RFID card emulation
- you want a polished consumer product rather than a DIY build
- you lack authorization over the cards you intend to emulate

## Facets
- artifact type: application
- maturity: maintenance
- function: security, embedded
- domain: security, hardware, embedded-systems
- platform: embedded, iot
- tags: magstripe, arduino, hardware-hacking, spoofer, security-research, electromagnetism, hardware
