UK customer Age Verification from AVUK is much more than just a pop box that anyone can tick to say that they are 18 years or over. 
The fundamental difference with this plugin is that it will take the name and address details your customer has used to register an account with on your website, and match against a database of UK people that contains date of births. 
Any website using WordPress and WooCommerce that sells age restricted products is required to prove they have only sold such products to customers over the age of 18. Verifying UK customers against actual data is the reliable and easy way to do this, with no inconvenience to your customers of manual age checks in the purchase process, thus reducing cart abandonment. 
Age restricted items include tobacco products and e-cigarettes, alcohol, 18+ films and computer games, bladed items, acids and other corrosive substances, offensive weapons, betting. This service uses a our API which is a 3rd party resource and requires an active credit balance.
Instant Age Verification
<h3></h3>
During the checkout process, your customer will input their name and address detail in registering for an account, or be logged in to an existing account containing these details. 
The plugin will instantly compare their name and address to a UK database and verify if they are age 18 or over. This age verification will be seamless in the background and your website’s process of checking out and paying for basket items will continue as normal. 
Any UK customer buying age restricted items that is not verified as 18+ will receive a message and be unable to proceed to purchase. You can then employ your own age checks on the customer and be able to flag them in the admin section as ‘manually verified’. They will then be allowed to purchase their age restricted items through your usual checkout process.
