Bucket is a technology platform which integrates with existing POS systems to facilitate coinless cash transactions at retail locations. With Bucket, every cash transaction will be fundamentally changed at the point of sale. Customers will pay in cash and use Bucket to digitally deposit the coin value of their change into a secure account. They now have access to lost or forgotten money and are provided with an effortless new medium to save. Retailers can reduce transaction time and operational expenses while increasing revenue by mobilizing this once idle revenue. By reducing coin currency overall, we can ultimately lower our carbon footprint generated through the wasteful production of coins and alleviate the stresses associated with the handling of physical coins by consumers and retailers alike.
