and transmitting the generated token to a merchant system. ## Claims ### Claim 1 A method for generating a token corresponding to sensitive data, the method comprising: receiving, by a processor separate from a merchant system, sensitive data from a user device via an interactive voice response system; generating, by the processor, a first token including a unique value associated with one or more specific transactions, wherein the first token is associated with the received sensitive data; and generating, by the processor, a second token based on the first token, wherein the second token applies to one or more subsequent transactions. ### Claim 2 (depends on 1) The method of claim 1, wherein the received sensitive data corresponds to cardholder data. ### Claim 3 (depends on 1) The method of claim 1, wherein the first token is valid for a predetermined period of time. ### Claim 4 (depends on 1) The method of claim 1, further comprising: prompting processing of a payment or transaction using the second token. ### Claim 5 (depends on 1) The method of claim 1, wherein the second token is used for transactions including returns or price adjustments. ### Claim 6 (depends on 1) The method of claim 1, further comprising: prompting suppression of sensitive data recording by the merchant system. ### Claim 7 (depends on 1) The method of claim 1, further comprising: generating or prompting a display corresponding to the received sensitive data. ### Claim 8 A system for generating a token corresponding to sensitive data, the system comprising: a data storage device storing instructions for generating a token corresponding to sensitive data, the sensitive data generated by an interactive voice response system; and a processor configured to execute the instructions to perform a method comprising: receiving, by a processor separate from a merchant system, sensitive data from a user device via the interactive voice response system; generating, by the processor, a first token including a unique value associated with one or more specific transactions, wherein the first token is associated with the received sensitive data; and generating, by the processor, a second token based on the first token, wherein the second token applies to one or more subsequent transactions. ### Claim 9 (depends on 8) The system of claim 8, wherein the received sensitive data corresponds to cardholder data. ### Claim 10 (depends on 8) The system of claim 8, wherein the first token applies to one specific transaction. ### Claim 11 (depends on 8) The system of claim 8, wherein the processor is further configured for: prompting processing of a payment or transaction using the high-value token. ### Claim 12 (depends on 8) The system of claim 8, wherein the token is used for transactions including returns or price adjustments. ### Claim 13 (depends on 8) The system of claim 8, wherein the processor is further configured for: prompting suppression of sensitive data recording by the merchant system. ### Claim 14 (depends on 8) The system of claim 8, wherein the processor is further configured for: generating or prompting a display corresponding to the received sensitive data. ### Claim 15 A non-transitory computer-readable medium storing instructions that, when executed by a transaction processor, cause the transaction processor to perform a method for generating a token corresponding to sensitive data, the method comprising: receiving, by a processor separate from a merchant system, sensitive data from a user device via an interactive voice response system; generating, by the processor, a first token including a unique value associated with one or more specific transactions, wherein the first token is associated with the received sensitive data; and generating, by the processor, a second token based on the first token, wherein the second token applies to one or more subsequent transactions. ### Claim 16 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the received sensitive data corresponds to cardholder data. ### Claim 17 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the first token applies to a specific transaction. ### Claim 18 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the second token is used for transactions including returns or price adjustments. ### Claim 19 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the transaction processor is further configured for: prompting suppression of sensitive data recording by the merchant system. ### Claim 20 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the transaction processor is further configured for: generating or prompting a display corresponding to the received sensitive data.
