Abstract

An enclosure for a biometric sensor is described. The enclosure comprises a cabinet having a plurality of surfaces. The biometric sensor placed inside the cabinet on a holder fixed on a primary surface from amongst the plurality of the surfaces. A secondary surface from amongst the plurality of surfaces is opposite to the primary surface. The secondary surface is substantially transparent to electromagnetic rays emitted by the biometric sensor.

Claims

1. An enclosure for securing a biometric sensor, the enclosure comprising a cabinet having a plurality of surfaces, wherein the biometric sensor is placed inside the cabinet on a holder fixed on a primary surface from amongst the plurality of the surfaces, and wherein a secondary surface opposite to the primary surface is substantially transparent to electromagnetic rays emitted by the biometric sensor.

2. The enclosure as claimed in claim 1, wherein a top surface of the biometric sensor and the secondary surface are at a predefined angle with respect to each other.

3. The enclosure as claimed in claim 2, wherein the predefined angle between the secondary surface and the top surface of the biometric sensor ranges from 3 degree to 35 degree.

4. The enclosure as claimed in claim 1, wherein the secondary surface has a curved shape.

5. The enclosure as claimed in claim 1, wherein the biometric sensor is one of a palm sensor, a finger print sensor, an iris sensor, a footprint sensor, a hand/feet geometry sensor, an ear lobe geometry sensor, and a face biometric sensor.

6. The enclosure as claimed in claim 5, wherein the palm sensor is Fujitsu palmsecure™

palm vein sensor.

7. The enclosure as claimed in claim 1, wherein the cabinet comprises a door with a locking mechanism to place and remove the biometric sensor in the cabinet.

8. The enclosure as claimed in claim 1, wherein the plurality of surfaces of the cabinet, other than the secondary surface are coated to absorb unwanted illuminations around the biometric sensor.

9. The enclosure as claimed in claim 1, wherein the secondary surface is one of clear glass, clear hardened glass, etched glass, etched hardened glass, partially etched glass, partially etched hardened glass, patterned etched glass, butter paper, translucent plastic sheet, acrylic sheet, and a combination thereof.

10. The enclosure as claimed in claim 1, wherein the secondary surface is placed in a field of view of the biometric sensor at a predefined distance such that the secondary surface is within focus of the biometric sensor.

11. The enclosure as claimed in claim 1, wherein the secondary surface is placed on a hardened glass sheet to secure the biometric sensor.

12. The enclosure as claimed in claim 1, wherein the secondary surface is coupled to a proximity sensor to activate the biometric sensor.

13. The enclosure as claimed in claim 1, wherein the secondary surface includes guide marks to guide a user.

14. The enclosure as claimed in claim 1, wherein a tertiary surface substantially transparent to the electromagnetic rays is overlaid on the secondary surface.
