Repair Services for Magnetic Stripe Readers

MSRs (Magnetic Stripe Readers) decipher the digital information stored on the magnetic stripe of credit/debit cards. Existing standards allow magnetic cards to store information in three separate tracks, each with a different bit density and encoded character set. A magnetic stripe reader consists of a read head made of a broken ring of magnetic metal wrapped in wire coils. Electric current flows through the coils to create an electromagnet. The coding in the reader allows for the first and second tracks to be read simultaneously. Advanced readers can read all three tracks at the same time. Due to specific programming of the microcontroller-based device, MSRs can read the card in either direction with a corresponding encoding format.
