Secure crypto currency point-of-sale (POS) management
A Point-Of-Sale (POS) terminal is equipped to process crypto currencies for transactions. The POS terminal generates a transaction-based digital wallet for a given transaction to receive a crypto currency payment for that given transaction. The transaction-based digital wallet, funded with the crypto currency for the given transaction, is transferred to a retailer's server where the crypto currency is transferred from the transaction-based digital wallet to a retailer's digital wallet for eventual exchange to a government issued currency.

receiving, by the processor, a payment option including a specific selected crypto currency payment as an indication that a customer is concluding a transaction at the POS terminal by paying with the crypto currency payment;
mapping, by the processor, a transaction identifier for the transaction to a specific identifier associated with a single digital wallet selected as one of the plurality of recycled digital wallets;
the processor uniquely associating and linking the single digital wallet to a transaction identifier for the transaction and maintaining a link between the specific identifier for the digital wallet to the transaction identifier associated with the transaction;
determining, by the processor, an exchange rate for a crypto currency associated with the specific selected crypto currency payment to a government issued currency;
determining, by the processor, an amount of the crypto currency based on the exchange rate and a transaction price in the government issued currency for the transaction;
