The need to increase micro-credit to small-scale entrepreneurs in Nigeria has called for innovative strategies in deposit-mobilization. Despite limitations and challenges peculiar to Nigerian micro-finance banks to deposit-mobilization initiatives, some banks have managed to deploy technologies to mitigate these constraints. This paper aims to identify the technologies and the capabilities responsible for enabling their deployment for deposit mobilization with a view to inform policy and management practice. Using data collected from questionnaire administration on the managers of 100 selected micro-finance banks, we identify the technologies deployed; measure investment, operational, marketing and linkage capabilities in the sector using a five-item scale (1 = none and 5 = very high) and examine the capabilities that influence the deployment of the technologies. We found out that 28.2% of the banks used Point-of-sale (POS) machines, 10.3% deployed mobile banking technologies, while 33.3% and 20.5% used mobile money and card system technologies respectively. The study revealed that technological capabilities in the sector ranged from moderate to high. Our regression model showed that capabilities to penetrate markets, procure and install equipment, negotiate and recruit skilled personnel were 21, 15.24, 5.75 and 0.03 times respectively more likely to influence the deployment of the POS. In addition, ability to link external agents to troubleshoot, test and train staff was 0.08 times more likely to influence the deployment of the POS. Capability to assess, procure and install technologies was 0.13 times more likely to influence the deployment of mobile money technologies. No capability was found to influence the deployment of mobile banking and card system technologies. This was attributed to the fact these technologies were deployed through commercial banks. The study recommended training through professional bodies and regulatory and knowledge institutions to upgrade technological capabilities in the sector
