rupee Symbol
₹ symbol has been in existence from a long time but people still use the regular Rs. term to indicate Indian Rupee. The main reason for this is difficult in finding the required font and not comfortable in using them. Digital Sensus provide you with an easy way to configure your computer one time and use a dedicated keyboard shortcut to use the ₹ symbol at your convenience. Please note that this shortcut can be used in Windows 7 OS and beyond.
