Update the Purchase Order payment option to make customers able to upload a copy of the purchase order during checkout.

I want a module where customers can simply pay in bitcoins, and stores can receive bitcoins.
Compared to before, credit card screening with regards to overseas payments has become stricter, and I think that the ratio of customers who cannot purchase is increasing.
In addition, even if the payment currency is different, the result is that exchange fees will become cheaper, and payment fees are also very cheap.
There is also the publicity benefit that stores are trying something new.

By all means, please implement this.

VISA Checkout implement PCI compliant credit card wallet for shoppers. Using this feature shoppers can easily access their credit cards stored in VISA Checkout and pay for products sold using X-Cart.

Authorize.Net Direct Post Method (DPM) is considered to be a solution that supports merchants to be PCI Compliant, as all Credit Card handling is done directly through Authorize.net, and no Credit Card data is handled/stored/processed on the merchant server.

Please check the links below to learn how the PDM solution work in contarst to the AIM solution:

The VeriFone MX880 CC machine (like the ones at Wal-Mart) are feature rich and ready for media support of a properly built interface. None of the CC processors that have low fees support the Xcart interfaces AND a proper counter top cc machine. Can't really talk about hassle free True integration until my brick and mortar customers can pay as easily as my online customers. Seems to me that a CC interface to the computer that passes the swipe or Chip Check. DEBIT is a must to keep fees down.

Square is very popular and many people love there service and fast payouts including myself! Please add square to your payment processing or I'm going to be force to move to different cart.

They now have API and can easily be added here, I've seen it on other shopping carts now but I didn't like there software, I like xcart but again because I use square for my retail store I would like to use it online as well.

Add NAB Payment Gateway (Hosted Payment Page) like in versions before 5!
