Those only react to the starch in the paper. Real currency isn't really 'paper', it's rag.
What you want for currency is an UV pen that will show the stripe and mini-writing on the stripe. The stripe is in different locations on the bill depending on denomination, and it's a different color too. Green on a twenty.
