摘要:
This invention relates generally to a method of preventing unauthorized access to a contactless device. The invention relates more particularly to the field of methods implemented so that an owner consent is provided to a reader before any access to its contactless device. The invention proposes to introduce slight modification on the behavior of the contactless device and an adaptation from the reader. With the present invention, the reader need to know in advance the UID of the contactless device he would like to establish a communication. The UID is generated by the reader from identity information provided by a positive action corresponding to a user consent. The present invention proposes to send a SELECT command directly to the corresponding contactless device with the complete UID, without using the ANTICOLLISION loop compliant with the standard 14443 type A. The contactless device will grant access to only reader sending a SELECT command with the complete UID.

Die may be thinned using a thinning and/or a polishing process. Such thinned die may be flexible and may change operational characteristics when flexed. Detection circuitry may also be provided on the PCB and may be used to detect changed operational characteristics. The thinned die may be stacked, interconnected, and encapsulated between sheets of laminate material to form a flexible card or device. A powered card may include a circuit board with multiple layers, and may include multiple reader communication devices. One of the layers may include an RFID antenna. A powered card may include a plurality of types of sensors used to detect a read-head of a card reader.

The invention relates to improvements in security substrates for security documents. The security substrate has at least two sets of regions having a machine detectable characteristic, in which only a first set of regions is applied to a first surface of the substrate. At least two sets of regions together form a machine readable code.

There is provided a card or token for use in financial transactions. The financial transaction token or card has an onboard energy storage device that enables onboard electronics to operate when the card is not in the proximity of a merchant Point-Of-Service (POS) terminal. In one implementation, the onboard energy storage device includes a capacitor such as a thin- film capacitor that stores sufficient energy to power onboard electronics without the need for an onboard battery. The card may be incorporated within various conventional apparatus such as a see-through and/or protective substrate, an item of clothing, an item of jewelry, a cell phone, a Personal Digital Assistant (PDA), a credit card, an identification card, a money holder, a wallet, a personal organizer, a keychain payment tag, and like personality.
