Abstract

A managing computing device positioned in an ATM can receive a dispense request for an amount of currency and account information from a user. A controller of a currency dispenser can generate a first number. The first number, the dispense request, and the account information can be sent to a remote, host computing device that shares a secret key with the controller. The host device can generate a first message authentication code (MAC) based on at least one of the first number and the amount of currency and can send it to the controller. The controller can generate a second MAC based on at least one of the first number and the amount of currency, confirm identity between the first and second MACs, and control the currency dispenser to dispense the amount of currency to the user.
