The electronic card can also be used to transmit a signal that can be received by the base station to perform a wide variety of tasks. These tasks can include launching an application, authenticating a user at a website, and completing a sales transaction at a website (e.g., by filling out a form automatically). The interaction between the base station and the electronic card is accomplished by using the conventional sound system in the base station so that a special reader hardware need not be installed to interact with the electronic card. The user is equipped with an electronic card that can receive and transmit data via sound waves. In the various embodiments, the sound waves can be audible or ultrasonic (which can be slightly audible to some groups of people). ## Claims ### Claim 1 A method for computer-implemented authenticating of a sound clip, comprising: receiving a sound clip from a source; dividing the sound clip into time slices; performing a feature calculation on at least some of the time slices; comparing each calculated feature with calculated features obtained from a database to determine a match; determining a number of matches from said comparing; and if the determined number of matches exceeds a predetermined threshold, authenticating the sound clip. ### Claim 2 (depends on 1) A method according to claim 1, wherein the source is an audio clip which is one of broadcast over telephone, cellular telephone, TV, broadcast over radio, webcast, and heard by an electronic cardholder. ### Claim 3 (depends on 1) A method according to claim 1, wherein said receiving is performed by an electronic card. ### Claim 4 (depends on 1) A method according to claim 1, wherein the sound clip includes at least one of a coupon, incentive points, and a sales offer. ### Claim 5 (depends on 3) A method according to claim 3, wherein the electronic card includes an analog recording function. ### Claim 6 (depends on 5) A method according to claim 5, further comprising amplifying, filtering, and gain controlling the analog sound clip prior to digitizing the analog sound clip by the electronic card. ### Claim 7 (depends on 1) A method according to claim 1, further including, after said receiving, transmitting at least some of the time slices of the sound clips to a remote server. ### Claim 8 (depends on 7) A method according to claim 7, wherein the server includes an authentication server. ### Claim 9 (depends on 1) A method according to claim 1, further comprising, after said receiving, at least one of sampling, normalizing, and filtering the sound clip. ### Claim 10 (depends on 9) A method according to claim 9, wherein said at least one of sampling, normalizing, and filtering the sound clip is performed by a pattern recognition search engine. ### Claim 11 (depends on 7) A method according to claim 7, wherein the remote server includes a database of sound clips. ### Claim 12 (depends on 11) A method according to claim 11, wherein the database includes audio files divided into time slices. ### Claim 13 (depends on 12) A method according to claim 12, wherein said authenticating includes comparing time slices of the sound clip with time slices of the database audio files. ### Claim 14 (depends on 1) A method according to claim 1, wherein each sound clip is from 5-10 seconds in length. ### Claim 15 (depends on 1) A method according to claim 1, wherein said extracting includes performing a time domain to frequency domain transformation process. ### Claim 16 (depends on 15) A method according to claim 15, wherein said performing a time domain to frequency domain transformation process includes performing one of a Fourier Transform, linear predictive coding (LPC), and a power spectral density transformation on the data in at least some of the time slices. ### Claim 17 (depends on 1) A method according to claim 1, wherein said dividing, extracting, performing a feature calculation, and comparing are performed at a server associated with a particular website. ### Claim 18 (depends on 17) A method according to claim 17 further comprising, after said authenticating, redirecting a user to the particular website. ### Claim 19 (depends on 18) A method according to claim 18, wherein the particular website is associated with a particular TV broadcast and wherein the particular website has Internet links to features of the TV broadcast. ### Claim 20 (depends on 18) A method according to claim 18, wherein the particular website is associated with a particular TV commercial and wherein the particular website is a merchant's webpage including Internet links to features of the TV commercial. ### Claim 21 (depends on 20) A method according to claim 20, further comprising registering an account on the merchant's webpage by the user. ### Claim 22 (depends on 21) A method according to claim 21 further comprising, after said registering an account, earning at least one of incentive points, mileage points, and coupons by the user. ### Claim 23 (depends on 1) A method according to claim 1, wherein said dividing, extracting, performing a feature calculation, and comparing are performed one of locally at a store and remotely at a server associated with a store. ### Claim 24 (depends on 5) A method according to claim 5, wherein the electronic card stores at least one virtual bookmark to at least one web address. ### Claim 25 (depends on 1) A method according to claim 1, wherein said dividing and said determining are performed by circuitry. ### Claim 26 A method for computer-implemented authenticating of a sound clip, comprising: receiving an audio clip from a broadcast TV commercial by an electronic card, wherein the audio clip includes at least one of a coupon, incentive points, and a sales offer;
