Generating barcodes utilizing cryptographic techniques
Various embodiments are generally directed to secure generation of barcodes using cryptographic techniques. An application may receive a request to generate a barcode. The application may receive encrypted data from a communications interface of a contactless card associated with an account. The application may receive, from a server, verification of the encrypted data and an encrypted authorization token associated with the account. The application may generate the barcode utilizing the encrypted authorization token.
1 . A method, comprising:
receiving, by an application executing on a processor, data from a contactless card associated with an account;
receiving, by the application and from a server, verification of the data and an authorization token associated with the account; and
generating, by the application, a scannable code utilizing the authorization token.
2 . The method of claim 1 , further comprising:
displaying, by the application, the scannable code on a display.
3 . The method of claim 1 , further comprising:
transmitting, by the application, the data to the server prior to receiving the verification of the data.
4 . The method of claim 1 , wherein the scannable code is pre-configured by the authorization token to authorize a single transaction.
5 . The method of claim 4 , wherein the scannable code and the authorization token are configured to expire after the authorization of the single transaction.
6 . The method of claim 5 , wherein the single transaction is a payment transaction and the authorization token is a payment token.
7 . The method of claim 6 , wherein the payment token is associated with a monetary limit.
8 . The method of claim 1 , wherein the contactless card comprises one or more Near Field Communication (NFC) Data Exchange Format (NDEF) tags, wherein the data is received from the one or more NDEF tags using Near Field Communication (NFC).
9 . A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processor, cause the processor to:
receive data from a contactless card associated with an account;
receive, from a server, verification of the data and an authorization token associated with the account; and
generate a scannable code utilizing the authorization token.
10 . The non-transitory computer-readable storage medium of claim 9 , wherein the instructions further cause the processor to:
display the scannable code on a display.
11 . The non-transitory computer-readable storage medium of claim 9 , wherein the scannable code is pre-configured by the authorization token to authorize a single transaction.
12 . The non-transitory computer-readable storage medium of claim 11 , wherein the scannable code and the authorization token are configured to expire after the authorization of the single transaction.
13 . The non-transitory computer-readable storage medium of claim 12 , wherein the single transaction is a payment transaction and the authorization token is a payment token, wherein the payment token is associated with a monetary limit.
14 . The non-transitory computer-readable storage medium of claim 9 , wherein the contactless card comprises one or more Near Field Communication (NFC) Data Exchange Format (NDEF) tags, wherein the data is received from the one or more NDEF tags using Near Field Communication (NFC).
15 . A computing apparatus comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the processor to:
receive data from a contactless card associated with an account;
receive, from a server, verification of the data and an authorization token associated with the account; and
generate a scannable code utilizing the authorization token.
16 . The computing apparatus of claim 15 , wherein the instructions further cause the processor to:
display the scannable code on a display.
17 . The computing apparatus of claim 15 , wherein the scannable code is pre-configured by the authorization token to authorize a single transaction.
18 . The computing apparatus of claim 17 , wherein the scannable code and the authorization token are configured to expire after the authorization of the single transaction.
19 . The computing apparatus of claim 18 , wherein the single transaction is a payment transaction and the authorization token is a payment token, wherein the payment token is associated with a monetary limit.
20 . The computing apparatus of claim 15 , wherein the contactless card comprises one or more Near Field Communication (NFC) Data Exchange Format (NDEF) tags, wherein the data is received from the one or more NDEF tags using Near Field Communication (NFC).
