Abstract
A biometric sensor apparatus for capturing patterns of blood vessels on the inner side of a wrist. The sensor apparatus has a strap with a near infrared camera mounted on a part of the strap. The camera is arranged for capturing an image of the blood vessels when it is temporarily held at an increased distance from the wrist than when the apparatus is simply being worn by the user. In some embodiments the camera is held at the required position for capturing the images of the blood vessels when the wrist strap is being opened or closed. In some embodiments the camera may be mounted in a deployant clasp of the wrist strap.
