Africa's digital economy will be built on mobile platforms
While the figures may differ, the message is the same: Africa's digital economy will be built on mobile platforms, creating exciting opportunities for farsighted mobile operators to play a key role in the continent's digital revolution.
As in many other developing markets in which mobile is outstripping fixed-line networks, mobile operators are becoming an important provider of, and platform for, a growing range of services.
Fifth generation networks will not only host new service types but will also require new infrastructure and network design to support them. Indeed, the move from 4G to 5G will be anything but straightforward. Are SA's telcos ready?

Kenya's M-Pesa money transfer service was developed partly by Vodafone, for example, and mobile operators are partnering with insurers, retailers, banks and other companies to provide a growing range of innovative services to Africans.

Ability to verify customer identity becoming a business imperative
In this growing ecosystem, payment solutions that are both secure and customer-friendly are of paramount importance. In particular, as mobile operators offer more and more services, identity fraud is becoming an issue. As a result, the ability to verify customer identity is becoming a business imperative for mobile operators.
However, traditional identity verification methods are subject to manual error and provide a frustrating customer experience. In contrast, a digital and automated identity verification solution can have an immediate impact on fraud reduction and even improve customer enrolment.
A powerful digital identity verification solution that is automated and integrated into the business process brings a new dimension to customer identity management. While there are a number of associated benefits, here we highlight the four key ones for mobile operators:
1. Reducing fraud
Deploying identity verification services can help to reduce fraud. In fact, according to the Technology Research Institute
, "real-time point-of-sale identity verification services are an invaluable aid in stopping fraudsters from exploiting identity theft".
For example, since Orange introduced Gemalto's identity verification tool, fraud in some stores was reduced by 100%. Additionally, performing identity verification in front of customers was found to discourage criminals from even attempting fraud.
2. Streamlining customer acquisition
Mobile operators offer customers a growing range of value-added services such as payments, internet of things services and peer-to-peer payment solutions, and this list is growing all the time. By deploying an identity verification solution, mobile operators could benefit from a consistent and unique digital identity that covers all services at the same time.
Therefore, when existing customers decide to buy a new service, or extend the functionality they already have, it can be done seamlessly and without any additional inconvenience by using their digital identity.
3. Providing better customer support
Deploying a solution that is user-friendly right from the start offers a real advantage because it can be improved over time by gathering feedback from sales staff.
In Orange's case, it allowed staff to focus on consumer care rather than on administrative tasks, helping to build stronger relationships. The reliability of the system was also of great benefit. Mobile operators often experience a huge volume of daily verification requests, but real-time identify verification in stores saves, literally, hundreds of hours.

Creating new opportunities through digital services. A multi-channel solution for identity verification, which also works remotely, provides a great opportunity for mobile operators to take the first step towards the creation of a trusted digital identity.
Mobile operators have the opportunity to position themselves as trusted digital identity aggregators by validating the subscriber's identity. This could then lead to further opportunities in complementary markets that require identity verification, from online gaming and banking to car rental. The opportunities in the public and private sector are legion.
Solutions that streamline identity verification, and protect customers' identities, are hugely valued by both customers and businesses. Finding the right balance between accuracy and tolerance for user convenience is critical in this field.
Mobile operators in Africa that adopt the technology now will see immediate benefits in terms of efficiency and customer service-but, in the long term, they will position themselves as pivots within the digital ecosystems built on mobile platforms.
