UV markings on bank notes, invisible markings on postal stamps, credit cards, cheque forms and identity cards are examples for the uses of fluorescence and phosphorescence. Less official uses are bus tickets, admission tickets or admission control. For this purpose a wide range of coding substances is available. For obvious reasons we cannot be more explicit here.
If you are interested in specific uses, please contact us. Phosphorescence occurs where a treated object glows in the dark. The glow effect itself is based on the laws of fluorescence.
