Abstract: Techniques are described for providing touchless ATM transactions based on receipt of a pre-staged transaction initiated by an authenticated user via an online banking system of a bank and subsequent receipt of a cryptogram of the user's payment card at an ATM. A server device receives transaction data for the pre-staged transaction from a user computing device via a user interface of an application associated with the online banking system. The server device associates the pre-staged transaction with a bank account including one or more payment cards of the user. The server device later receives a cryptogram of a payment card from an ATM and, based on identification information included in the cryptogram, determines that the payment card at the ATM is one of the payment cards of the bank account associated with the pre-staged transaction. In response, the server device authorizes performance of the pre-staged transaction at the ATM.
