A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable to act as a magnetic stripe read-head detector and a data transmitter. A multiple layer flexible PCB may be fabricated to include multiple magnetic emulators. An emulator may include a coil that includes magnetic, ferromagnetic, or ferromagnetic, material in the coil's interior. Coils may be associated with zones. As a read-head is detected to move from zone-to-zone, coils may be activated to transmit information in those zones.

Cards and devices with magnetic emulators with zoning control and advanced interiors

A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Gift cards may be inputted by a user into such a payment card or other device such that a user can combine gift cards. Similarly, a user be provided with a global payment account that can be utilized in multiple countries that have different standards for formatting data. A user may be provided with a default country (e.g., United States) but may have a way to select that the user is in a different country (e.g., Japan). Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

Payment cards and devices with gift card, global integration, and magnetic stripe reader communication functionality

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable of communicating information to a magnetic stripe reader. Information used in validating a financial transaction is encrypted based on time such that a validating server requires receipt of the appropriate encrypted information for a period of time to validate a transaction for that period of time. Such dynamic information may be communicated using such an emulator such that a card may be swiped through a magnetic stripe reader&#x2014;yet communicate different information based on time. An emulator may receive information as well as communicate information to a variety of receivers (e.g., an RFID receiver).

Cards and devices with multifunction magnetic emulators and methods for using same

A card is provided, such as a credit card or security card, that may transmit information to a magnetic stripe reader via a magnetic emulator. The emulator may transmit the information serially in order to reduce the amount of circuitry needed to emulate a particular block of information. Additionally, for example, a serial encoder may send any amount of information through a single emulation segment. Such a magnetic emulator may be provided on a credit card. A dynamic credit card number may be provided by, for example, coding a number with a different coding scheme for different periods of time. The magnetic emulator may be utilized to transmit a particular coded number for a particular period of time. In this manner, a dynamic credit card number may be provided such that to help secure, and progress, a payment transaction.

Cards and devices with multifunction magnetic emulators and methods for using the same

Dynamic magnetic stripe communications devices are provided as magnetic stripe emulators. A magnetic stripe emulator may include a coil. Drive circuits may be coupled to this coil in order to produce electromagnetic fields from the coil operable to communicate with a magnetic stripe reader.
