In certain embodiments, indication-related detectable changes on a transaction token may be facilitated. In some embodiments, a transaction card may determine a state of the transaction card (e.g., during an interaction with a transaction terminal). The transaction card may generate a signal related to a color based on the state of the transaction card and cause the signal to be transmitted to a change element of the transaction card. The change element may be configured such that the change element causes one or more edges or other portions of the transaction card to be (i) a first color in response to the signal being a first signal and (ii) a second color in response to the signal being a second signal. As an example, the portions of the transaction card may turn red when the signal is a first voltage and green when the signal is a second voltage.
