Methods and apparatus for enabling secure network-based transactions
An apparatus includes a transaction card bearing data and having an output interface capable of transmitting the data, a card reader having an input interface enabled to accept the data from the output interface of the transaction card, conversion circuitry converting the card data to an analog modulated signal, and an output pin from the card reader adapted to engage in a microphone port of a computerized appliance, the output pin providing the analog modulated signal to the port, and thence to the computerized appliance.
1. An apparatus comprising:
a card reader having an input interface configured to accept transaction data from an output interface of a transaction card, and an output pin, as a part of the card reader, configured to directly connect the card reader to a microphone port of a smart telephone, the card reader providing the transaction data accepted from the output interface of the transaction card to the output pin, and hence to the microphone port, as an analog variable voltage audio signal; and
coded instructions stored in a non-transitory medium of a first Internet-connected server, and accessible by a user of the card reader;
wherein the coded instructions, when executed on a processor in the smart telephone, convert the analog variable voltage audio signal received at the microphone port to the transaction data as digital data, establish direct data exchange between the smart telephone and a second Internet-connected server and facilitate transactions by a financial institution, or purchases from an online-merchant, using the transaction data.
2. The apparatus of claim 1 wherein the coded instructions, when executed on a processor in the smart telephone, retrieve a card verification code (CVV), and use the CVV in purchases or transactions.
3. A method comprising:
accepting transaction data from a transaction card at an input interface of a card reader having an output pin as a part of the card reader, the output pin directly connecting the card reader in a microphone port of a smart telephone;
receiving the transaction data in the smart telephone as an analog variable voltage audio signal from the microphone port of the smart telephone;
converting the analog variable voltage audio signal received at the microphone port to the transaction data as digital data;
establishing direct data exchange with an Internet-connected server providing services to a financial institution or an on-line merchant by executing coded instructions on a processor in the smart telephone; and
facilitating transactions with the financial institution or purchases from the on-line merchant, using the transaction data.
4. The method of claim 3 wherein the coded instructions, when executed on a processor in the smart telephone, retrieve a card verification code (CVV) from the transaction data received on the microphone port, and use the CVV in the purchases or transactions.
