Interrupt pin assignment so, if you have one of these, connect the wires like this instead (swapped clock/data wires): Arduino Pin The Arduino Leonardo or Arduino Micro (or other arduinos based on the ATmega32U4 processor) have a diferent menu inside the Arduino IDE and a new 'MagStripe' entry should appear in the Sketch > Include Library and File > Examples menus.Ĭonnect your card reader to the following digital pins of the Arduino Uno (or other arduinos based on the Then open it from the Sketch > Include Library > Add. Installationĭownload the latest zip file from the releases section. Check your reader's datasheet if you're not sure how your reader behaves. This behavior is not supported by this library. Insert-type readers usually have the CLS pin connected to a switch instead (active high when the card is fully inserted and low otherwise). Note: This library is designed for swipe-type readers (like the one pictured above) meaning it requires the CLS pin to be active low while the card is being swiped and high otherwise. Which can read all three tracks by repositioning the head, or theĮxample of another reader which can only read track 2 and has a different pin arrangement. Varying colors for each wire, but usually there are five wires with the following order and function: With screws allowing the head to be manually positioned to choose one of the tracks.

There are many brands of TTL magnetic card readers on the market, some with a fixed reading head and others It supports reading any of the cards' possible three tracks, but not simultaneously. MagStripe is an Arduino library to interface with TTL (raw) magnetic card readers.
