Abstract: The present invention relates to systems and methods for enhancement of biometric object image capturing. These systems and methods prevent undesirable interruptions of total internal reflection of a prism that result in improper biometric images. In embodiments of the invention, a thermal assembly comprising a plurality of thermal elements is placed adjacent to the image capturing device. The thermal elements upon supply of a current are capable of either heating or cooling the image capturing device or a platen of the image capturing device. If cooling of the biometric object receiving surface is required, the thermal elements can be controlled to decrease temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed.

Abstract: A wireless transceiver device is used to conduct a secure electronic sales transaction. In an embodiment, the wireless device is used to obtain a fingerprint of the individual wanting to make a purchase. The wireless device then transmits the fingerprint to a device coupled to a cash register, which sends the fingerprint to a third party verification service. The third party verification service uses the received fingerprint to verify the identity of the purchaser by matching the received fingerprint to fingerprint data stored in a database. The identity of the purchaser can then be sent to the cash register and to a credit service. The credit service uses the data from the third party verification service to approve sales information received from the cash register and to prevent the unauthorized use of a credit account.

Abstract: A method and apparatus for rolled fingerprint capture is described. The start of a fingerprint roll is detected. A plurality of fingerprint image frames are captured. A centroid window corresponding to each of the plurality of captured fingerprint image frames is determined. Pixels of each determined centroid window are knitted into a composite fingerprint image. The end of the fingerprint roll is detected.

Abstract: An access control unit interface between a fingerprint scanner and a host processor is described. A daughter card is coupled between the fingerprint scanner, various access control peripherals, and the host processor. The host processor can be any commercially available processor. The daughter card handles real-time and interactive access control events. The daughter card may include an access control interface processor. The access control interface processor may include a display interface module, a keyboard module, a Wiegand interface module, a finger detect interface module, a LED interface module, and a serial communication module.

Abstract: A code reader incorporated into a fingerprint scanner for viewing of security items such as credit cards, bank cards, passports and the like and comparing embedded coding on the item to an individual's fingerprint. In this manner, the imaging plane can be used to view the security items in combination with scanning the fingerprint of the individual for comparison.

Abstract: A method and apparatus whereby a fingerprint verifier has a mechanism to slide a prism over an imaged area of a camera. The position of the prism being determined by a binary absolute linear code on a sliding mechanism imaged by the same camera at the side of the fingerprint wherein the images are knitted together to simulate a large CCD.

Abstract: A portable fingerprint recognition transmitter that is compact, being less than the size of a cigarette pack, allowing the fingerprint recognition transmitter to be carried by an individual in a pocket or purse. The fingerprint recognition transmitter operates to take the image of the fingerprint and formulates a fingerprint image capable of transmitting through infrared or radio frequency to a receiver having previously stored fingerprint images so as to cause a comparison between the image taken and the image stored for purposes of unlocking a security area.
