Device Swap API

The Device Swap API enables new layers of security to be integrated into digital services, providing protection against mobile device transitions. It is designed to detect unauthorised changes, which could result in potential fraud. It provides real-time information about whether the SIM card associated with a mobile phone number has been transferred to another device.

This solution helps with the identification of phone swaps using the same number, strengthening the security measures that organisations can offer to prevent fraudulent access and protect the identity of their users. It also allows for immediate alerts and additional authentication measures to mitigate risks.

What can it be used for?

The integration of the Device Swap API enables early detection of suspicious device swaps, helping to mitigate risks before they become unauthorised actions. Businesses can avoid financial losses, reduce security breaches and maintain customer confidence.

This tool complements existing security measures by adding an additional layer of protection without affecting the user experience. It integrates with authentication mechanisms such as 2FA or risk-based authentication systems to provide stronger defences against digital fraud.

FRAUD DETECTION

The Device Swap API provides a service to prevent fraud by identifying, in real time, device swaps for a phone number. This allows companies to trigger alerts for suspicious activity and apply additional identity verification steps, preventing unauthorised access to accounts and theft of customer data.

IDENTITY AUTHENTICATION

With device swap verification, this tool facilitates identity validation at critical points in the process, such as logging into accounts, executing transactions or resetting passwords.

PERSONALISED COMMUNICATION

This API allows data-driven messaging and recommendations to be generated, improving the customer experience. It facilitates the sending of notifications about related services when a device swap is detected, as well as informing users with older phones about possible upgrade options.

SIMPLIFIED INTEGRATION

Thanks to the standardisation of this tool, developers can make use of its capabilities, without the need for customised implementations per telecom carrier, reducing complexity and reducing the time to market. This is because it offers a unified, Telco-independent interface, enabling faster and more efficient integration in commercial environments.

ACCESS TO TELCO CAPABILITIES

The Device Swap API is developed within the CAMARA framework, thus ensuring a unified use of telecom industry functionalities, such as detection and management of device swap events. This standardisation enables seamless scaling across multiple carriers and markets, facilitating interoperability between different infrastructures and service providers.

OPTIMISED DEVELOPMENTS

The design of this API is focused on speeding up the developer's work, to avoid the challenges that can be posed by carrier's specific requirements. This allows them to focus on creating more advanced and innovative solutions, reducing development times and ensuring frictionless implementation.

Use cases

Financial services & insurance

Real-time security measures

Real-time data is a particularly useful tool in the fight against digital fraud, as having up-to-date information helps to streamline the processes to act in case of risk. The integration of the Device Swap API into fraud detection systems helps to immediately detect unauthorised device swaps to prevent account takeovers. This enables layered authentication processes to be enabled, additional layers of security to be activated and fraudulent transactions to be proactively blocked, thereby strengthening user confidence and the security of digital transactions.

Personalised messages to users

Offering communications tailored to customer's needs allows companies to optimise their sales opportunities. By analysing Device Swap API data, companies can design specific marketing strategies based on device swaps, such as offering services associated with a new phone or discounts to users with older devices. This allows to achieve crucial factors for an organisation such as launching quality messages, creating cross-selling opportunities and retaining customers. It also facilitates advanced user segmentation, enabling more effective and personalised strategies.

Advanced identity checks

With digital fraud on the rise, companies are facing increasing challenges to protect their customers, especially in processes such as application logins. Having information such as device swaps for a SIM card can help improve identity verification processes. The Device Swap API helps to detect such suspicious movements in real time, allowing the automatic activation of additional security measures, such as multi-factor authentication or biometric validation requests. In this way, companies can react quickly to possible unauthorised access, minimising customer friction, so that they can carry out a smooth navigation that does not affect their user experience.

Policy compliance on corporate lines

Incorrect use of business phones can be a security and cost breach for companies. It is therefore essential to ensure the proper use of these devices and to control the monitoring of the organisation's policies. Thanks to the Device Swap API, unauthorised device swaps can be identified, allowing automated alerts to be generated and usage restrictions to be applied based on corporate policy. This ensures that employees do not misuse corporate plans for personal devices, reducing security risks and optimising operational costs.
