Abstract: An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

Abstract: A user device transmits a digital representation of a document or contract to a document or contract validation system through one or more channels. The document or contract validation system validates the document or contract before submitting the document or contract to a transaction system as a valid transaction. The digital representation of the document or contract may include one or more sets of parameters that are useful in the validation process.

Abstract: A mobile device includes a smartcard controller that does not rely on power received from an interrogating RF field. The mobile device also includes a small inductive device capable of inductive coupling with an RFID reader. The smartcard controller includes circuitry to modulate an impedance of a port coupled to the inductive element when in the presence of an interrogating RF field at substantially 13.56 MHz.

Abstract: A mobile device is described with apparatus and software for fast and secure access to banking information. In at least one embodiment, a mobile device comprises an antenna; and one or more circuitries coupled to the antenna, wherein the one or more circuitries are to execute instructions to receive account information for a user directly from a financial institution based at least in part on direct interaction with the financial institution without having a device, which is not the mobile device, interact with the financial institution to gather the account information.

Abstract: A mobile device is described having an antenna to detect a communication target from a point-of-user-interaction apparatus near the mobile device. The mobile device includes a reader that initiates a transmission of a command to the point-of-user-interaction apparatus and reads a response from the point-of-user-interaction apparatus. A display unit changes its display based on the response and/or the communication target. A circuitry executes instructions to receive a first authentication information from the point-of-user-interaction apparatus. The point-of-user-interaction apparatus transmits a second authentication information to a computing device. The circuitry executes instructions to send the first authentication information to the computing device.
