I'm currently evaluating whether Firebase will be suitable for an app I am making. The only potential sticking point I have found is taking payments - what are the options currently available? Kato Firebase is a real-time data store, focused on lightning-fast, scalable solutions for sharing data between hundreds to millions of clients simultaneously. It does not offer any payment processing solutions internally.

I am looking for any advice regarding best practices considering our requirements (listed below) and any additional heads-up for common pitfalls or specific issues I should be giving special consideration. The payment gateway we will be using is PaymentExpress as it's one of the few supported gateways that has recurring billing and doesn't have any special conditions for

Say you've got a credit card number with an expiration date of 05/08 - i.e. May 2008. Does that mean the card expires on the morning of the 1st of May 2008, or the night of the 31st of May 2008? It took me a couple of minutes to find a site that I could source for this. The card is valid until the last day of the month indicated, after the last [sic] 1 day of the next month; the card cannot be used to make a purchase if the merchant attempts to obtain an authorization. - Source Also, while looking this up, I found an interesting article on Microsoft's website using an example like this, exec
