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.
