Nowadays technology advances at a furious pace. As a result, the financial sector is becoming increasingly modernized. Two hundred different currencies have been used in countries all around the world. As a result of the increased operations, the monetary traversal has increased. This necessitates the use of automated currency recognition python software.

  Cash recognition technology essentially aims to discover and retrieve visual and unseen properties of banknotes. E-banking, money monitoring devices, currency exchange machinery, and other technologies are among the possibilities. This article will provide a complete picture of currency recognition python where you will get complete information essential for doing projects in the field. We will first understand the characteristic features in a currency note which are determined for authentication

Characteristics for currency note authentication

• Serial number
  • Just on the upper left and lower right sides, there is a serial number display with banknote numbers that expand in size from small to large.
• Watermark
  • A picture of Mahatma Gandhi appears, along with multidimensional stripes and a mark indicating the denomination number, which may be seen while holding up the currency to the light.
• Security thread
  • On currencies with color changes, it is a 3mm panelled safety thread containing markings in Hindi, RBI mark, and currency number.
  • Whenever the note is twisted, the thread color transitions from green to blue.
• Mark for identification
  • A marking with printmaking print that could be sensed by touching aids blind people in recognizing denominations.
  • The marking has five stripes in the five hundred denomination and seven lines in the two thousand denominations.
• Latent image
  • On the right-hand side, a straight stripe on the front faces of the denomination.
  • When the currency is placed sideways at the line of sight, it includes a latent picture of the denomination’s number.

These are the basic characteristic features in a currency note which are analysed and identified to determine authenticity.
