A smartcard receives biometric capabilities by incorporating a biometric sensor chip based on a “dual” flip chip bonding technique. In particular embodiments, the sensor chip may be incorporated into the card-type substrate after having completed any high temperature process steps required for laminating the various foil layers of the card-type substrate.

The disclosed embodiments provide a payment card. The payment card may have a first face and a second face opposite the first. Additionally, the payment card may comprise a first smart chip, the first smart chip having contacts that are electronically accessible from the first face of the card. The payment card may further comprise a first antenna coupled to the first smart chip, the first antenna providing near-field contactless access to the first smart chip and a second smart chip, the second smart chip having contacts that are electronically accessible from the second face of the card. Additionally, the payment card may comprise a second antenna coupled to the second smart chip, the second antenna providing near-field contactless access to the second smart chip and an RF block that electronically isolates the first antenna and the second antenna from each other.

Systems and methods for overmolding a card are provided. A chip fraud prevention system include a device including a chip and a substrate. The chip may be at least partially encompassed in a chip pocket, and the substrate may be at least partially encompassed by the overmold.

Example embodiments of information-shielding cards and systems and methods of fabricating the same are provided. An information-shielding card can comprising a substrate comprising a first layer, a second layer, a third layer, a chip embedded in the second layer, and a quick-response (QR) code formed on the second layer. The second layer can be disposed between the first layer and the third layer. The first layer can comprise a first material that is transparent when exposed to a non-visible light, the second layer can comprise a second material that is opaque when exposed to visible light and when exposed to non-visible light, and the third layer comprises a third material that is transparent when exposed to a non-visible light.

A radio frequency identification (RFID) tag with a configurable anti-tamper structure includes an RFID chip electrically connected to a configurable anti-tamper structure. The configurable anti-tamper structure includes a plurality of conductive segments substantially oriented in a ladder configuration. At least some of the plurality of conductive segments are cut to leave a single conductive path in accordance to the desired tamper detection application, and the RFID tag is attached with the anti-tamper structure placed across a break point to be monitored for tampering. When tampering occurs, the conductive path is broken and the RFID chip changes the data sent in response to interrogation by an RFID reader.
