The invention relates to a security transfer element, a value document, comprising a security element layer composite, a method for checking a value document, a bank note processing device and a system comprising bank note processing device and security transfer element and / or value document. The security transfer element comprises a security element layer composite with a functional layer, the functional layer developing an optically variable effect for an observer. On the side of the functional layer opposite the viewer, the security element layer composite has at least one luminescent substance. The luminescent substance has primary emission radiation in a wavelength range between 700 nm and 2100 nm and can be excited by excitation radiation in the wavelength range between 400 nm and 2100 nm. Furthermore, the functional layer is opaque for the emission radiation of the luminescent substance.
