How does a blind person differentiate between bills and coins when paying? 🦮🤯
Blind people use various methods to differentiate between bills and coins when paying. Many bills have different sizes or textures that they can feel with their fingers, and in some countries, the edges of coins have different reliefs depending on the denomination. There are also mobile apps that, by pointing the camera at a bill or coin, identify its value aloud. Additionally, some portable devices or "bill readers" are another practical tool for quickly and accurately identifying money.
