Computer-based systems and device configured for temporary electronic account linking to disposable tags and methods thereof

A method comprising:

• providing a physical card having a contactless communication tag physically attached thereto;
• receiving, by at least one processor, an electronic account activity request from at least one computing device;
• wherein the electronic account activity request comprises:
• i) a tag identifier decoded from an encoded tag data of a contactless radio signal data of a contactless radio signal emitted by a contactless communication tag in response to an interrogation signal by a contactless reader of the at least one computing device;
• ii) a data transfer content associated with a requested data transfer, and
• iii) a transferee account identifier identifying a destination account for the requested data transfer;
• determining, by the at least one processor, an account link that links the contactless communication tag to a user account by using the tag identifier to refer to a unique disposable account card identifier;
• wherein the account link comprises an expiration period;
• wherein the expiration period is configured to cause the at least one processor to unlink the unique disposable account number from the user account at the end of the expiration period;
• determining, by the at least one processor, disposable account card identifier associated with the tag identifier based on the account link;
• wherein the disposable account card identifier comprising a unique disposable account number;
• generating, by the at least one processor, an account activity authorization associated with the disposable account card identifier to fulfill the electronic account activity request by transferring the requested transfer quantity from the user account to the destination account based at least in part on the unique disposable account number, the data transfer content and the transferee account identifier;
• updating, by the at least one processor, a disposable account card interface and a user interface element;
• wherein the disposable account card interface is configured to allow a user to delete the account link to remove the disposable account card data from the user account;
• and
• causing to display, by the at least one processor, the disposable account card interface on a display of at least one computing device associated with the contactless reader.

A system comprising:

• a physical card having a contactless communication tag physically attached thereto;
• at least one processor configured to implement instructions causing the at least one processor to perform steps to:
• receive, via an antenna module from a contactless reader, a contactless radio signal data of a contactless radio signal emitted by a contactless communication tag in response to an interrogation signal;
• wherein the contactless radio signal data comprises encoded tag data;
• wherein the encoded tag data comprises a tag identifier of the contactless communication tag;
• determine that the contactless communication tag is a new contactless communication tag based on the tag identifier being unlinked to any user account;
• generate a disposable account card data for a user account, the disposable account card data comprising a unique disposable account number;
• wherein the user account comprises a permanent account number different from the unique disposable account number;
• generate an account link that links the tag identifier to:
• the disposable account card data, and
• the permanent account number associated with the user account;
• wherein the account link comprises an expiration period;
• wherein the expiration period is configured to cause the at least one processor to unlink the unique disposable account number from the user account at the end of the expiration period;
• writing, by the at least one processor using a return contactless radio signal, the unique disposable account number to the tag data of the contactless communication tag of the physical card to enable contactless user account activity using the user account via the unique disposable account number in place of the permanent account number;
• generate a disposable account card interface and a user interface element;
• wherein the disposable account card interface is configured to allow the user to perform the contactless electronic requests with the contactless communication tag and wherein the user interface element is configured to enable a user to delete the account link to remove a reference between the disposable account card identifier and the user account;
• and
• cause to display the disposable account card interface on a display of at least one computing device associated with the contactless reader.
