This invention is a simple system and method for making U.S. banknotes easily readable by all visually-impaired persons, without requiring major changes to the way U.S. currency is now produced, nor the replacement of millions of existing vending, ATM, and currency counting machines. The system slightly modifies the six lowest-denomination U.S. banknotes, $1 through $50, by truncating a small section from different corners of each denomination. This enables a visually-impaired person to hold the banknote in any orientation and determine by feel its correct denomination. The specific sequence of truncated corners has been designed so that no banknote can be altered by truncating additional corners to make it feel like a higher-value banknote to a visually-impaired person. The invention eliminates all problems created by systems using embossed or embedded characters, different-size denominations, hand-held currency reading devices, and other systems which have been proposed for assisting visually-impaired persons to read currency.
