The opaque thin film material used to cover the Personal
Identification Numbers (PIN) on mobile phone scratch cards
for three GSM lines coded A,B and C is collected in three
separate small plastic bottles. The substance is introduced
to the nozzle of an XRF machine in order to determine its
elemental composition. Results show that the substance used
by all the three GSM lines to cover the PIN on their
respective scratch cards mainly contains metals such as
titanium, potassium, iron, calcium and zinc. It also shows
complete absence of radioactive isotopes such as Uranium,
Thorium, Radium or polonium in the substance. The
implications of these findings are discussed in the paper.
