PayPal may go after Square's mobile payments

PayPal is planning to take on Square with a new payment processing dongle, says a report from GigaOM. The dongle will supposedly tie into PayPal's already robust payment processing system and will be targeted towards small businesses. Smaller companies would be able to use this system to process credit card transaction at the office or in the field. PayPal says its technology will become "the future of commerce for small businesses." The eBay subsidiary is expected to unveil its new mobile payment system on Thursday.
