Automated teller machines (ATMs) having offline functionality

An automated teller machine (ATM), comprising:

• one or more memories;
• and
• one or more processors communicatively coupled to the one or more memories, configured to:
• determine that the ATM is disconnected from a network;
• implement, based on determining that the ATM is disconnected from the network, a backup mode;
• receive, based on the ATM being in the backup mode, a request for currency related to a first device;
• receive authentication information;
• establish, based on pairing with a second device associated with the first device, a communication channel with the second device;
• authorize the request for currency based on a comparison of the authentication information and customer data that is stored locally in a memory device of the ATM,
• wherein establishing the communication channel causes authorization of the request for currency one time during a predetermined time period and prevents the request for currency being authorized another time during the predetermined time period;
• determine a maximum value of currency to be dispensed based on authorizing the request for currency,
• wherein the maximum value of currency is based on a timing aspect associated with the ATM;
• generate transaction data associated with the authorized request,
• wherein the transaction data identifies a value of currency, associated with the authorized request, that does not exceed the maximum value of currency;
• and
• store the transaction data associated with the authorized request in the memory device.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of an automated teller machine (ATM), cause the one or more processors to:
• determine that the ATM is disconnected from a network;
• implement, based on determining that the ATM is disconnected from the network, a backup mode;
• receive, based on the ATM being in the backup mode, a request for currency related to a first device;
• receive authentication information;
• establish, based on pairing with a second device associated with the first device, a communication channel with the second device;
• authorize the request for currency based on a comparison of the authentication information and customer data that is stored locally in a memory device of the ATM,
• wherein establishing the communication channel causes authorization of the request for currency one time during a predetermined time period and prevents the request for currency being authorized another time during the predetermined time period;
• determine a maximum value of currency to be dispensed based on authorizing the request for currency,
• wherein the maximum value of currency is based on a timing aspect associated with the ATM;
• generate transaction data associated with the authorized request,
• wherein the transaction data identifies a value of currency, associated with the authorized request, that does not exceed the maximum value of currency;
• and
• store the transaction data associated with the authorized request in the memory device.
