That soccer ball Putin gave Trump really did have a transmitter chip in it, logo indicates
The ball presented to the US President in Helsinki contained a chip with a tiny antenna that transmits to nearby phones – a featured advertised by maker Adidas

Russian President Vladimir Putin’s gift of a soccer ball to US President Donald Trump last week set off a chorus of warnings – some of them only half in jest – that the World Cup souvenir could be bugged. Republican Senator Lindsey Graham even tweeted, “I’d check the soccer ball for listening devices and never allow it in the White House.”
It turns out they weren’t entirely wrong. Markings on the ball indicate that it contained a chip with a tiny antenna that transmits to nearby phones.

The chip allows fans to access player videos, competitions and other content by bringing their mobile devices close to the ball. The feature is included in the 2018 Fifa World Cup match ball that’s sold on the Adidas website for US$165 (reduced to US$83 in the past week).
Adidas declined to comment on whether the chip could be a vector of a Russian hack. There is no suggestion that such balls or their chips have any security vulnerabilities. The chip itself can’t be modified, according to the product description on the Adidas website. “It is not possible to delete or rewrite the encoded parameters,” it says.
While the logo on the ball advertised the presence of the chip, it couldn’t be determined from the photos whether the chip might have been removed, replaced with actual spy gear, or, even more remotely, whether the entire ball itself was fabricated for the event and only resembled the Adidas model in question.
