Buycott.com is an Internet-based platform and smart-phone application that reads the Universal Product Codes (UPC) barcode on a product, and suggests whether a consumer should buy or avoid that product based on how well it aligns with the consumer's values and principles. The consumer joins to various Buycott campaigns to indicate their support or their opposition to various issues and topics. The app prevents them from purchasing from corporate entities - and their affiliates - that endorse policies which conflict with those campaigns. The consumer can thus "vote with their wallet", and opt to purchase a competing product, or forgoing the purchase altogether.
