Gerasimos Livieratos is the Business Development Manager at iSquare S.A., a company that has developed a mobile wallet app. The document summarizes that while mobile wallets have long been anticipated, most previous attempts have disappointed or not been widely adopted. iSquare's mobile wallet app aims to be truly private and secure by not revealing any personal customer information to merchants, unlike traditional mobile payment methods. It uses NFC, Touch ID, and a secure element for contactless payments directly from an iPhone without disclosing names, credit card numbers, or security codes during transactions.
