An autonomous and portable smartcard reader device incorporates a high level of embedded security countermeasures. Data transfers are encrypted with specific input devices, namely a light sensor/DTMF/infrared and PIN or other keyboard entry, and at the output through the use of a dual-tone encoder-decoder. The unit may be used alone or as a plug-in to another device such as a PDA, cell phone, or remote control. The reader may further be coupled to various biometric or plug-in devices to achieve at least five levels of authentication, namely, (1) the smartcard itself; (2) the smartcard reader; (2) the PIN; (3) private-key cryptography (PKI); and (5) the (optional) biometric device. These five levels account for an extremely strong authentication applicable to public networking on public/private computers, and even on TV (satellite, cable, DVD, CD AUDIO, software applications. Transactions including payments may be carried out without any risk of communication tampering, authentication misconduct or identity theft. In essence, the device is a closed box with communication ports. The emulation of the device is therefore extremely complex due to the fact that it involves PKI, hardware serialization for communication and software implementation, in conjunction with a specific hardware embodiment and service usage infrastructure component that returns a response necessary for each unique transaction link to an atomic time synchronization.

The method of claim 11, wherein the multi-tone acoustic signal is an audio frequency shift keying (AFSK) signal. 14. The method of claim 11, wherein the multi-tone acoustic signal is a private line (PL) signal. 15. The method of claim 1, wherein the initiating of a transaction request at the card reader unit includes the entry of a personal identification number (PIN) through a keyboard. 16. The method of claim 15, wherein the keyboard includes a touch-sensitive screen. 17. The method of claim 15, further including terminating the operation of the portable card reader unit if a PIN entry is attempted more than a predetermined number of times. 18. The method of claim 1, wherein the portable card reader unit further includes a biometric input; and the initiating of the transaction in the device with the server or another party includes receiving biometric data through a biometric input. 19. The method of claim 18, wherein the biometric input is a fingerprint. 20. The method of claim 1, wherein information exchange subsequent to the transaction request are encrypted. 21. The method of claim 20, wherein the encryption is based on public-key cryptography. 22. The method of claim 20, wherein the encryption is based on identity-based encryption (IBE) cryptography. 23.
