The Adidas website explains that the technology gives users access to "different functionalities," including "exclusive information about the product, adidas football content, special competitions and challenges."

It is unclear whether the ball Putin gave Trump the the advertised device – and even if it does not mean it necessarily poses a security risk.
According to the Adidas website, the technology works by interacting with smartphones or tablets enabled with "Near Field Communication," which describes the "digital technology" each other. "
Scott Schober, a cybersecurity expert, said in an interview that the technology would be unlikely to be used for espionage and that there would be a US President.
"This is the kind of technology used for mobile payment with smartphones, in this case typically within a couple of centimeters "he said.
Schober added, "They're probably going to X-ray it and sweep it to see if there's any radio frequency emanating out of it."
There has already been speculation, however, that the poison might not be secure.
The same day that Putin gave Trump the soccer ball, South Carolina's Republican Sen. Lindsey Graham tweeted a warning
saying that "if it were me, I'd check the soccer ball for listening devices and never allow it in the White House. "
Adidas did not immediately claim it could be compromised by hackers. Its website states that "it is not possible to delete or rewrite the encoded parameters".
During the presidential conference, Putin's gifted footballer Trump stunned observers – and prompted a rebuke from top Republicans in Congress – by declining to endorse the US intelligence community that Russia had interfered with in the 2016 US presidential election.
Following the news conference, Director of National Intelligence Dan Coats issued a statement
saying Moscow's "efforts to undermine our democracy" are "ongoing" and "pervasive."
Amid a backlash, Trump later said he had failed during the news conference.
