magento2 – How can I get information about cards with customer data?

I receive information cards, but I have to show it to the customer, for example, to show a specific product, its name, its price and the customer who bought this product.
Get information about the cart

class Index expands  Magento  Framework  View  Element  Template
{

public service __construct (

 Background  Backend  Block  Template  Context $ context,

 Magento  Checkout  Model  Cart $ cart,

$ data array []

   )

{

$ this-> cart = $ cart;

parent :: __ construct ($ context, $ data);

}

public function getCartInfo ()
{

return $ this-> cart-> getQuote () -> getItemsCollection ();

}

}

Anyone can help?
