In order to facilitate conducting a financial transaction via wireless communication between an electronic device (such as a smartphone) and another electronic device (such as another smartphone), a secure element in the electronic device may generate, using an encryption key associated with the secure element, a signed blob based on a transaction amount and a merchant identifier. Then, the electronic device communicates connection information between the electronic device and the other electronic device. Moreover, the electronic device may establish a connection between the electronic device and the other electronic device based on the connection information, and may concurrently provide the signed blob to the other electronic device. After receiving a signed transaction blob from the other electronic device using the connection (which includes information needed to conduct the financial transaction), the electronic device provides the information to a server to conduct the financial transaction. |

1. An electronic device, comprising:
an antenna; an interface circuit, coupled to the antenna and a secure element, configured to communicate with another electronic device; and the secure element configured to:
receive a transaction amount associated with a financial transaction;generate, using an encryption key associated with the secure element, a signed blob based on the transaction amount and a merchant identifier;communicate, via the interface circuit, connection information between the electronic device and the other electronic device;establish, via the interface circuit, a connection between the electronic device and the other electronic device based on the connection information;provide, via the interface circuit, the signed blob to the other electronic device;receive, via the interface circuit, a signed transaction blob from the other electronic device using the connection, wherein the signed transaction blob includes the transaction amount, the merchant identifier, and financial-account information that specifies a financial account; andprovide, via the interface circuit, information associated with the signed transaction blob to a server to conduct the financial transaction. |
