They provide mobile payment solutions and simple 2-factor web authentication solutions—all 100% operator and handset agnostic. Their patented technology, NSDT (Near Sound Data Transfer), uses any phone’s audio channel to transmit encrypted transaction data (e.g. one-time-passwords, electronic signatures, certificates…).
Last year, they released TagPay, a complete mobile payment platform powered by NSDT. It offers a secure and convenient mobile payment service that is free and works with any phone.
