Claim 19:
20. A non-transitory machine-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform steps comprising:
receiving, by a server and from a mobile device, an identification of a transaction card and first data associated with a first plurality of signals, wherein the first plurality of signals are transmitted by one or more first devices in physical proximity to the transaction card and detected by the transaction card via a periodic scan;
storing, as a profile associated with the transaction card, the one or more first devices;
receiving, by the server and from the mobile device, the identification of the transaction card and second data associated with a second plurality of signals, wherein the second plurality of signals are detected by the transaction card via the periodic scan;
determining, by the server and based on the second plurality of signals, one or more second devices to be in physical proximity to the transaction card;
storing, as an updated profile associated with the transaction card, the one or more second devices;
receiving, by the server and from a point-of-sale (POS) terminal at a time of an attempted transaction, the identification of the transaction card and third data associated with a third plurality of signals, wherein the third plurality of signals are transmitted by one or more third devices in physical proximity to the transaction card and detected by the transaction card at the time of the attempted transaction;
determining, by the server, whether the one or more third devices associated with the third plurality of signals comprise a subset of devices in the updated profile, wherein the devices in the updated profile comprise one or more profile devices selected from the first devices or the second devices or a combination of the first devices and the second devices;
generating, by the server and based on a determination that the one or more third devices do not comprise the subset of the devices in the updated profile, a message that the attempted transaction is unauthorized; and
sending, to the POS terminal, the message that the attempted transaction is unauthorized.
