This paper uses built-in Xenon flashlight in today's smartphones to experimentally replace the magnetic card. Due to the high dependence of the users nowadays on their smartphones and their wide availability and use in nearly all everyday tasks, the idea of integrating smartphones in financial transactions such as payments and withdrawals has attracted the interest of many researchers. Therefore, in this paper, we experimentally modulate the embedded Xenon flashlight in a smartphone with the
