For decades, coin lock systems have dominated airports and train stations, offering a way to rent carts in exchange for local currency. But as travel has evolved, so too have the needs of passengers. Today, this outdated system poses more problems than benefits. Whether it’s struggling to find the right coins, machines not accepting foreign currency, or locks jamming at the worst moment, travelers are left frustrated and stressed. CartR is here to change that. By replacing coin locks with a user-friendly digital platform, CartR removes all the headaches associated with outdated systems. Instead of hunting for change, travelers can now simply scan and unlock a cart through the CartR app in seconds, no coins required.
