Patent attributes
Various embodiments are related to apparatuses and methods for authorizing a purchase transaction using a mobile device. A consumer can pay for a purchase from a seller using a payment object such as a credit card or automated teller machine (ATM) card. The credit card or ATM card can be swiped through a card reader that is part of the seller's sales system, and the sales system can transmit the purchase transaction to a financial system for approval. The consumer can use a mobile device such as a smartphone, instead of the seller's keypad or signature pad, to electronically capture a signature or personal identification number (PIN) as part of the consumer's authorization of the purchase transaction. The consumer can further use the mobile device to review line items of the purchase transaction or to add a tip amount to the total amount of the purchase transaction.
