A decoding system with a decoding engine running on a tablet. The decoding engine decodes signals produced from a read of a buyer's financial transaction card, accepts and initializes incoming signals from a read of a buyer's financial transaction card until the signals reach a steady state, detects the read of the buyer's financial transaction card once the incoming signals are in a steady stat, identifies peaks in the incoming signals and digitizes the identified peaks in the incoming signals into bits. A transaction engine runs on the tablet and is coupled to the decoding engine. A payment system is in communication with the transaction engine and with a buyer's financial transaction card institution or a first party's financial account.

Approaches provide for a mobile point-of-sale system configured to facilitate the transfer of funds between entities (e.g., customers and merchants). A card reader can include two different types of slots configured for conducting a financial transaction between entities. A first slot can allow for a magnetic stripe element of a card to be swiped. A second slot can include contact elements which allow the card to be 'dipped in'. In this way, the device can receive a swipe and/or a 'dipping' of a card into a respective slot for conducting a financial transaction.
