Because the cash out voucher can be reinserted into the slot machine, and it can be used in place of cash within the casino, it is equipped with the fluorescent security factor.
The cash out voucher below is one which is actually being used in casino in Korea and the US, and nothing appears under natural light. However, the hidden security factor shows up when placed under the UV light.
This is the cash out voucher used in Korean casinos. Nothing shows up on the front, but the casino's logo shows up on the back. Both the front and back consists of fluorescent paper, but the security factor show up clearly.
This is the cash voucher used in the US casinos. Just like above, nothing shows up on the front, but the casino's logo shows up on the back. The other cash out voucher uses only fluorescent fiber, and no other fluorescent factor is added.(Does not show clearly in photo.)

Because the automatic exchanger only exchanges the voucher of a certain limit, and if you win a huge amount at the slot machine, you must go to the cage for the exchange. This is when the secure factor is utilized. Through the primary barcode, the high value voucher is checked for validity, and once more, checked for secure factor. This is because there is possibility of forgery.
Forgery of chips or cash out vouchers at the casino is illegal and subject to punishment.
