Patent attributes
Embodiments of the present invention are directed to methods, systems, and apparatuses for enabling payment information received via a reader device coupled to a mobile point-of-sale (POS) terminal to be communicated in a secure manner to a third party service provider for payment processing of a transaction between a merchant and a consumer. Some embodiments are directed to communication of the payment information received from a reader device using a payment processing mechanism (e.g., a hosted order page) of the merchant to process payment information via the third party service provider in a secure manner. The reader device can encrypt payment information using a third party encryption mechanism, such as derived unique key per transaction (DUKPT). The third party encryption mechanism can be used or accessed by the third party service provider to enable end-to-end security for payment processing.
