User-activated payment card
First Claim
1. A payment card, comprising:
- a transducer configured to detect a presence or an absence of a gating signal, which is provided by an external source;
an enable circuit, electrically coupled to the transducer, which is configured to provide an enable signal based on the detected gating signal; and
a wireless communication circuit, electrically coupled to the enable circuit, configured to provide financial information, which is stored on the payment card, when an external signal is received and when the enable signal is present.

Abstract
Embodiments of a payment card (such as a credit card), a financial-transaction system that uses the payment card, and a method are described. These embodiments may be used to protect financial information stored on the payment card, while providing ease of use to a user of the payment card when conducting a financial transaction. In particular, the payment card may include a transducer that detects a physical phenomenon. If this physical phenomenon is detected, a wireless communication circuit in or on the payment card is enabled, so that the wireless communication circuit can provide the user'"'"'s financial information in response to an external signal received from an external reading device (such as an a radio-frequency identification signal from a card reader).
