PayPal released some new public numbers that show the payments platform is processing a massive number of payments per day, according to TechCrunch.

PayPal says that it saw $3,650 in Total Payment Volume every second in Q2 2011. That means PayPal is processing around $315.3 million in payments per day. On average, the payments platform is seeing upwards of over 5 million transactions a day.

This past quarter, PayPal delivered its first-ever billion dollar revenue quarter. Total net total payment volume (TPV) grew 34% compared to the same period of last year.

Another area where PayPal is growing fast is mobile. The company said earlier this year that is seeing $10 million in mobile transactions per day, and expects more than $3 billion in mobile TPV this year, compared to $750 million in 2010.

PayPal wants to also tackle in-store payments as well and will be debuting several retail partnerships for this technology this year. And Facebook is generating a fair amount of volume for PayPal as well. It should be interesting to see what eBay and Facebook have up their sleeves in a few weeks.

With the way that the payments platform is growing, this number should increase in 2011.
