Uruguay, a country recognized for its commitment to the environment, faced a daily paradox: although the law prohibited plastic bags, many people still forgot to bring their reusable bags when shopping. This led them to buy a new bag on each visit, which went against the original purpose of reducing consumption. To solve this, we created a smart, reusable bag, linked to a unique discount code associated with the customer's ID. By simply scanning it, users accessed a personalized series of daily discounts, transforming the shopping routine into an unforgettable experience, both for their finances and for the planet.
