We already know there are solid theoretical basis for rebuilding 3d spaces from photos. Infrared imaging doesn't dramatically get different data from a regular camera except maybe picking up your veins a bit more clearly.
There aren't a bunch of other sensors available.. probably some heat/temperature just to make sure it's a real palm but that's not for uniqueness.
No doubt there are 3D scanners (to map the elevation of your palms, the depth of the lines, etc.), infrared imaging and a slew of other minor sensors. To make this fast, they need to effectively correlate enough of the data to identify you without relying solely on a single thing.
