AT&T plans to pilot a new service that it says will arm companies with the ability to confirm the location of participating customers who opt in to advanced fraud protection when they travel internationally.

Businesses will gain the ability to access AT&T network data to locate a participating user's device, authenticating the user's location and helping to protect against fraud, according to a news release.

The service, which is enabled through an application program interface, can proactively notify companies when their customers who opt in for the service arrive in a new country.

For instance, a bankcard issuer could confirm that its customer has traveled to a new country as soon as she lands and turns on her mobile device. This would allow the company to make better informed decisions about approving or declining transactions in an international country.

AT&T plans to make the new Location Information Services capability available in more than 150 countries. The company will begin a pilot this summer, and expects to deploy the service to enterprise customers later this year.
