Claims

1. A method for supporting the verification of a security document (4), wherein said security docu-ment (4) comprises at least one electrically conductive structure (7), comprising the steps of

detecting, by means of a touchscreen (2) of a verification device, a presence, position and orientation of said conductive structure (7) on said touchscreen (2), a.nd

displaying, on said touchscreen (2) , at least one image (12, 22, 25, 32, 33) whose position and/or orientation depends on the position and orientation of said conductive structure (7) .

2. The method of claim 1 wherein the position and orientation of said image (12, 22, 25, 32, 33) depends on the position and orientation of said conductive structure (7) .

3. The method of any of the preceding claims wherein said security document (4) comprises an interaction region (10, 26) , wherein said method comprises the steps of

calculating, from the position and orientation of said conductive structure (7), a position and orientation of said interaction region (10, 26) and

adjusting a position and orientation of at least a first region of said image (12, 22, 25, 32, 33) to be located in said interaction region (10, 26) .

4. The method of claim 3 wherein the interac-tion region (10, 26) of said security document (4) comprises a window (10), in particular is a window (10), of said security document (4) .

5. The method of any of the claims 3 or 4 wherein said interaction region (10, 26) carries a first repetitive pattern (24) and said first region of said image (12, 22, 25, 32, 33) carries a second repetitive (25) pattern, wherein said first and said second repetitive patterns (24, 25) have substantially equal spatial frequency.

6. The method of any of the claims 3 to 5 wherein said interaction region (10, 26) comprises a fluorescent or metameric material (26) and wherein light emitted by said touchscreen (2) in said first region of the image (12, 22, 25, 32, 33) has a spectrum suitable to generate fluorescence in said fluorescent material (26) or to change a color of said metameric material (26) .

7. The method of any of the claims 3 to 6 wherein said metal structure (7) extends around at least half of said interaction region (10, 26) .

8. The method of any of the preceding claims comprising the steps of

providing an original picture (20),

applying a first part (21) of said original picture (20) to said document (4), and

displaying at least a second part (22) of said original picture (20) as at least part of said image (12, 22, 25, 32, 33) on said touchscreen (2) in such an orientation and position that the first and second parts (21, 22) of the picture combine to re-create a larger part of said original picture (20) than said first part (21) only.

9. The method of any of the preceding claims comprising the step of animating said image (12, 22, 25, 32, 33) .

10. The method of claim 9 wherein said image (12, 22, 25, 32, 33) is animated when said document (4) is at rest against said touchscreen (2) .

11. The method of any of the claims 9 or 10 wherein said image (12, 22, 25, 32, 33) is animated to follow said document (4) when said document (4) is moved in respect to said touchscreen (2) .

12. The method of any of the preceding claims comprising the step of

detecting, by means of said touchscreen (2), a finger gesture indicative of a user touching said document (4) while said document (4) is placed against said touch screen,

determining, from the position and orientation of said conductive structure (7) as well as from the location of said finger gesture, a touched part {30, 31) of the document (4) touched by the user, and

choosing said image (12, 22, 25, 32, 33) or an animation displayed on said touchscreen (2) or a sound played by said verification device as a function of the touched part (30, 31) .

13. The method of any of the preceding claims comprising the steps of

calculating, from the position and orientation of said conductive structure (7), at least one non-covered region of said touchscreen (2) that is not covered by said security document (4), and

selectively positioning at least part of said image (12, 22, 25, 32, 33) in said non-covered region.

14. A verification device comprising a control unit and a touchscreen (2), wherein said verification device is adapted and structured to carry out the method of any of the preceding claims.
