Block Diagram - Magnetic Card Reader
PSoC programmable analog and digital resources integrate everything shown in the light blue block below. Click on the colored blocks to view or sample the recommended PSoC Components.

 

The flexibility of PSoC allows you to customize each colored block, or PSoC Component, to meet your design requirements through the easy-to-use PSoC Creator Software IDE.  These Components are available as pre-built, pre-characterized IP elements in PSoC Creator.


Design Considerations
Magnetic Card Readers (also known as Magnetic Stripe Readers or MSRs) read data from a 3-track magnetic stripe via a peak detection circuit and process that data for downstream users. After extracting data from the magnetic stripe, it is converted to binary data and formatted for encryption.

PSoC 3 and PSoC 5 allow a scalable solution that enables 3-channel peak detection, data conversion and formatting, and encryption on a single chip. Integration into a single chip allows small form factor designs that can be put into the reader head assembly to improve security. PSoC's scalability also allows for optional capsense button pads and/or LCD displays.
