The box has the electronic intelligence to accept multi denomination coins such as one, two and five rupees, which facilitate the caller to talk comfortably. According to Navitel officials, the smart payphone would not dispense balance change, which could be utilised for next call. Over the next few days, BSNL and Navitel will set up these smart payphones at Malar Hospital, the Government General Hospital and Chennai Central station.
The city would have coin-operated phones in 200 locations in a months time. The cards would be re-usable and could be topped up whenever needed.
Phones with wireless technology would also be introduced in remote areas, rail coaches, deluxe buses, parks and stadiums.
All the Chennai phones would be linked to a centralised payphone management system at Tiruvanmiyur, that would co-ordinate functioning, security features, revenue collection, maintenance and automatic fault reporting through an intelligent network platform.
The phone could also be upgraded to meet 3G standards, and in future, would offer video communication facilities to the public, Mr Chinnaiyan said.
