A payer transaction device enables secure offline transactions using a secure element providing a secure payer account database, a secure ledger database, and a wallet application. While the payer transaction device is not connected to the Internet, the wallet application receives a payee identifier and a transaction amount and verifies that the transaction amount is less than an available payer account balance in the secure payer account database. In response, the wallet application creates a digital token that allocates the transaction amount from the payer account balance to the payee identifier, and records the digital token in a payer secure ledger in the secure ledger database, which reduces the available payer account balance by the transaction amount. The wallet application then transfers the digital token to a payee transaction device over a peer-to-peer wireless connection and, subsequently, the digital token is synchronized with a ledger tracking system through the Internet.

A user's location is determined by location information communicated by a user device, such as a smart phone. Merchants near the user location are determined and selected. Merchant payment information is transmitted to the user device so that the user can easily make a payment to the merchant through the user device. Merchant offerings may also be sent to the user device for purchase and subsequent payment, where the merchant offerings may be specifically selected for the user.

Location based transactions

A system is configured to perform operations that include causing a merchant device to display a first visual code. The operations further include receiving a request to initiate a payment transaction between a consumer and a merchant, the request to initiate the payment transaction being transmitted to the system in response to a consumer device of the consumer scanning the first visual code displayed by the merchant device. The operations also include causing funds to be transferred from an account of the consumer to an account of the merchant. Further, the operations include in response to determining, based on one or more criteria, an occurrence of a code change event, causing the merchant device to display a second visual code in replacement of the first visual code.
