Abstract: Transaction verification mechanisms are provided that receive transaction information, from a computing device at a transaction location, including user device information specifying one or more user device identifiers associated with a user initiating a transaction, vendor device information specifying a plurality of vendor device identifiers in a near field area associated with the computing device, and account information for an account being used to perform the transaction. A user device verification is performed on the one or more user device identifiers and a vendor device verification of the plurality of vendor device identifiers is performed to verify the transaction location as being an authorized vendor location. A determination whether to approve/deny completion of the transaction at the computing device is performed based on results of the user device verification and the vendor device verification and an output is sent to the computing device based on the determination.
