Today, mobile phones have become a lifeline for entrepreneurs. They have more or less integrated as an essential element in their day-to-day life. Mobile phones are not only used for swift communication, but often for used for payment of bills, e-commerce shopping, health monitoring, GPS navigation, and so on and so forth.
A similar progressive trend is observed with access control, which initiated with RFID Cards, then expanded with biometrics and is now being enhanced with advanced mobile credentials like Bluetooth.
