This is why the BoE (Bank of England) is trying to move to plastic-based cash. And they pass microbes better too.

“The technology, which has been developed by Dr John Bond OBE from the University of Leicester’s Department of Chemistry, uses a specially tailored UV light source to visualise fingerprints not possible to see otherwise on ‘thermal paper’ — that is, the paper used for shop receipts and for bank statements from ATMs.

Historically, the process of visualising fingerprints on thermal paper has been problematic, as the solvent used in the chemical treatment can colour the dye and turn the whole paper black, rendering thermal paper a ‘problem surface’ to recover fingerprints from.

The new technology developed by Dr Bond counters these issues, making it possible to identify fingerprints on all forms of thermal paper efficiently.

Dr Bond said: “This new technology offers a new way of easily looking for fingerprints on an increasing source of paperwork that criminals are likely to handle when committing a variety of offences.”
