UV can be faked. Check multiple security features including raised ink and microprinting for the Birds $5/$10.
Always check at least two security features. One should be feeling the raised ink by running your fingernail against the lines in the shoulder of the portrait, and the other should be a visible feature such as the watermark, split leaves in the holographic strip, windowed thread appearing solid against the light, from the new Journey notes, or microprinting on any note.
