ValiDeck is an idea to build a search engine on the back of endorsements and rejections that are credibly captured by Internet users. The endorsements and rejections can be captured: 1) manually, following a card/cash transaction; 2) automatically, following a card/cash transaction - e.g. when you purchase the same product / visit the same service provider (e.g. doctor) repeatedly or discontinue purchasing a product / visiting the service provider; and 3) manually, without any transaction - e.g. when you borrow a book from a friend. The ValiDeck Rank or Voice of the People (VOP) will be a numerical score derived from the mathematical relationship between endorsements and rejections, Voice of the Consumer (VOC) and Voice of the Expert (VOX).
