Secure facilitation of virtual card activities for procurement

A secure transaction facilitation system comprising:

• a computing device executing a software service for facilitating transactions between a buyer account and a supplier account;
• a supplier device comprising an electronic digital display screen, the supplier device usable by an operator of the supplier account to access virtual payment card data associated with the buyer account;
• wherein the computing device comprises a processor and main memory, the main memory comprising instructions which, when executed, cause:
• storing, by the software service, a first virtual payment card data and a second virtual payment card data, the first virtual payment card data and the second virtual payment card data being sufficient to uniquely identify a particular payment method associated with a first buyer account and a second buyer account;
• receiving, from the supplier device, a request to view the first virtual payment card data and the second virtual payment card data;
• causing displaying, on the electronic digital display screen of the supplier device, visual virtual payment card data corresponding to the first virtual payment card data and the second virtual payment card data in a first visual state;
• determining, by the software service, one or more abnormal behaviors has occurred by determining that the supplier account accessed the first virtual payment card data and the second virtual payment card data during a time period that does not exceed a normality threshold;
• and
• causing visually altering, on the electronic digital display screen of the supplier device, the visual virtual payment card data corresponding to the first virtual payment card data and the second virtual payment card data into a second visual state that is different from the first visual state and preventing, by the software service, access to the first virtual payment card data and the second virtual payment card data.

A computer-implemented method comprising:

• maintaining, on a computing device, a software service that is programmed for facilitating procurement transactions between a buyer account and a supplier account;
• receiving, from the buyer account at the software service, a first virtual payment card data and a second virtual payment card data, the first virtual payment card data and the second virtual payment card data being sufficient to uniquely identify a particular payment method associated with a first buyer account and a second buyer account;
• receiving, from the supplier account at the software service, a request to access the first virtual payment card data and the second virtual payment card data associated with a virtual card method of purchase;
• storing, in a secure storage memory of the software service, visual virtual payment card data corresponding to a visual representation of the first virtual payment card data and the second virtual payment card data;
• providing, to the supplier account, access to the secure storage memory;
• determining, by the software service, that one or more access actions by the supplier account correspond to one or more abnormal access behaviors by determining that the supplier account accessed the first virtual payment card data and the second virtual payment card data during a time period that does not exceed a normality threshold;
• and
• in response to determining that the one or more access actions correspond to one or more abnormal access behaviors, preventing, by the software service, access to the first virtual payment card data and the second virtual payment card data.
