WhoIsIn is a web-based biometric attendance tracking system, focused on tracking the attendance and employee movements especially for business with multiple offices. WhoIsIn uses a biometric USB finger print scanner and the internet to offer the most accurate information possible for the Human resources, Operations teams and the Management. Other attendance tracking systems focus only on tracking the entry and exit of employees, while WhoIsIn additionally and uniquely tracks the presence of the employee in the office too. WhoIsIn is offered on a Software-as-a-Service (SaaS) model, where there is no capital expenditure (on the Hardware & Software), but only operational expenses. The charges are calculated based on the number of employees, devices deployed etc.
