swIDch: Fin Auth

According to the Nilson Report, credit card fraud causes damage to the global economy of $27.85 billion annually, and the damage is expected to reach $40.6 billion by 2027. In addition, incidents of information theft in the short-text one-time password (OTP) or digital authentication process used for bank account transfers continue to occur. Adding extra security layers and procedures for safer financial transactions is never the answer. swIDch provides authentication solutions that allows anyone to conduct financial transactions easily and conveniently, as well as fundamentally block external threats in the identity and transaction authentication process.
