First Claim
1. A method for communicating with a magnetic stripe reader having a magnetic read head, comprising the steps of:
- activating an electronic apparatus from an off state to a reduced power mode;
detecting the magnetic stripe reader;
activating the electronic apparatus from the reduced power mode to a full power mode after detection of the magnetic read head; and
broadcasting a signal that contains a transaction specific data packet that is read by the magnetic read head;
wherein the signal is broadcast without using a static magnetic stripe and the signal is a time varying and spatial varying magnetic field that is interpreted by the magnetic read head as originating from a standard magnetic stripe.

Abstract
A method for communicating with a magnetic stripe reader which has a magnetic read head by activating the electronic apparatus from an off state to a reduced power mode, then detecting the magnetic stripe reader, then activating the electronic apparatus from the reduced power mode to a full power mode after detection of the magnetic read head, and then broadcasting a signal that contains a transaction specific data packet that is read by the magnetic read head. The signal is broadcast without using a static magnetic stripe and it is a time varying and spatial varying magnetic field that is interpreted by the magnetic read head as originating from a standard magnetic stripe. A monitoring system can be used to identify what type of point-of-transaction terminal is being used to read the electronic apparatus and choose a timing of the magnetic stripe broadcaster to accommodate it.

19. A method for conducting a transaction with an electronic card, comprising the steps of:
-
detecting a magnetic stripe reader head of a magnetic stripe reader by a sensor of the electronic card; after the magnetic stripe reader head has been detected by the sensor, activating a full power mode of the electronic card in which a transaction specific dynamic field of data is generated within the electronic card; and broadcasting the transaction specific dynamic field of data to the magnetic stripe reader head in a signal by use of a magnetic stripe broadcaster; wherein the signal is a time varying and spatial varying magnetic field that is interpreted by the magnetic read head as originating from a standard magnetic stripe. - View Dependent Claims (20)
