Show EAN13 on product page

[@diegofrancesco]

Hello, 

I have read some thread but I haven't found a specific solution. I need to put the EAN13 reference on product page, under the short description or under the long description. How can I do that?

Now I have the EAN on product details. 

My PS version is 1.7.2.4

Thanks for your support.

Add {$product.ean13} in the product.tpl to the spot you need,
