Abstract: A device implementing a system for preventing duplicate wireless transactions includes a wireless communication controller that is configured to receive a signal for conducting a wireless transaction with a wireless transaction terminal. The wireless communication controller is further configured to determine whether a transaction type of the wireless transaction is associated with a signal strength threshold. The wireless communication controller is further configured to measure a signal strength associated with the wireless transaction upon determining that the transaction type of the wireless transaction is associated with the signal strength threshold. The wireless communication controller is further configured to prevent the wireless transaction from completing when the transaction type of the wireless transaction is associated with the signal strength threshold and the measured signal strength fails to satisfy the signal strength threshold, otherwise allow the wireless transaction to complete.
