A one-euro coin token is a small, circular piece of metal that is used to release a shopping cart from a shopping cart corral. The token is inserted into a slot in the cart, which unlocks the cart from the corral. When the cart is returned to the corral, the token is released and can be used again.
One-euro coin tokens are a common sight in European countries, where they are used in most grocery stores and other large retailers. The use of one-euro coin tokens is designed to encourage shoppers to return their carts to the corral, which helps to reduce litter and make the shopping experience more convenient for everyone.
