Abstract
A magnetic stripe reader assembly for a point of sale terminal is provided. The magnetic stripe reader reads the account data from a card and may encrypt it within the magnetic head. An encrypted representation of the account data may be provided to a host processor in the terminal for carrying out a financial transaction, such as a payment for goods or services. The account data is typically recorded on the magnetic stripe on the card in a magnetic flux pattern that is sensed and then converted to an analog signal. Such sensing and conversion and other processing of the account data to produce the encrypted representation of the account data typically involves one or more parameters, and may include at least one parameter that is adjustable.
