Hidden Secret on Currency Notes: Lines for the Visually Impaired

• Currency notes feature raised, slanted lines on their edges, not for design, but for a crucial purpose.
• These 'bleed lines' are designed to help visually impaired individuals identify the denomination of notes by touch.
• Different denominations have distinct line patterns: 100 rupee notes have 4 lines, 200 rupee notes have 4 lines with two circles, and 500 rupee notes have 5 lines.
• The raised texture is created using 'Intaglio Printing', a technique also used globally for currency.
• RBI also provides the 'MANI App' which scans notes and announces their value via voice, further aiding the visually impaired.

Why It Matters: The raised lines on currency notes are a thoughtful design for visually impaired individuals to identify denominations.
