Sparkasse Hannover Chooses Diebold Nixdorf as End-to-End Managed Services Provider Sparkasse Hannover has transferred the entire IT management and operations of its 450 ATMs to Diebold Nixdorf Managed Services. As a top German savings bank, Sparkasse Hannover has pursued a customer-centric, omnichannel approach to banking services across its 100 locations. Since Diebold Nixdorf has taken over the operation, management and lifecycle management of all self-service banking devices, Sparkasse Hannover’s clients have experienced significant service quality improvements – with ATM availability rising to over 99%. This higher availability means improved customer experience, higher client satisfaction, more transactions at the ATMs, increased sales and fewer interruptions for branch staff.
