Information and Communication Technology (ICT) is one of the Models used by Bank of Baroda for implementation of Financial Inclusion. ICT based models are (i) POS, (ii) Kiosk. POS is based on Application Service Provider (ASP) model with smart cards based technology for financial inclusion under the model, BCs are appointed by banks and CBCs These BCs are provided with point-of-service(POS) devices, using which they carry out transaction for the smart card holders at their doorsteps. The customers can operate their account using their smart cards through biometric authentication. In this system all transactions processed by the BC are online real time basis in core banking of bank. PoS devices deployed in the field are capable to process the transaction on the basis of Smart Card, Account number (card less), Aadhar number (AEPS) transactions.
