Answer
jokerupdatesite.com is a site that claims to sell CVV and dumps. CVV means the card verification value printed on a payment card. Dumps means card data copied from a magnetic stripe. Buying or selling this data is illegal in the US. The site is not a legitimate financial service.
What the site claims
The site markets 'fresh' card data. It uses terms from carding forums. Carding is the trade in stolen payment card data. The site does not publish a business address or a license. It does not show a connection to a bank or a payment processor.
Legal status in the US
18 U.S.C. § 1029 makes it a federal crime to traffic in unauthorized access devices. Payment card numbers and CVVs count as access devices. A conviction can bring a prison term and a fine. The US Department of Justice prosecutes carding cases. The FBI runs payment card fraud investigations.
Scam risk
Carding sites have no recourse for buyers. A buyer cannot report a missing delivery to a bank or a regulator. Sellers can take payment and send no data. Sellers can send data that does not work. The site can close and reopen under a new name. The 'fresh' label is a sales claim. The buyer cannot verify the data before payment.

What to do instead
Do not buy card data from jokerupdatesite.com or any similar site. If you have a payment card, monitor your statements. Report unauthorized charges to your card issuer. Report card fraud to the FBI Internet Crime Complaint Center. If you receive stolen card data, do not use it. Delete it and report the contact.
