Methods, systems, and media for protected near-field communications

A system for protected near-field communications, the system comprising:

• a memory;
• and
• a hardware processor coupled to the memory that is programmed to:
• receive, by an NFC reader device, an NFC tag device ID of an NFC tag device;
• determine whether the received NFC tag device ID matches an NFC tag device ID stored in memory of the NFC reader device;
• in response to determining that the received NFC tag device ID matches the NFC tag device ID stored in the memory of the NFC reader device, transmit a password to the NFC tag device;
• receive, from the NFC tag device, a shared secret;
• determine whether the received shared secret matches a shared secret stored in the memory of the NFC reader device;
• and
• in response to determining that the received shared secret matches the shared secret stored in the memory of the NFC reader device, cause an action to be performed by a device associated with the NFC reader device.

A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for protected near-field communications, the method comprising:

• receiving, by an NFC reader device, an NFC tag device ID of an NFC tag device;
• determining whether the received NFC tag device ID matches an NFC tag device ID stored in memory of the NFC reader device;
• in response to determining that the received NFC tag device ID matches the NFC tag device ID stored in the memory of the NFC reader device, transmitting a password to the NFC tag device;
• receiving, from the NFC tag device, a shared secret;
• determining whether the received shared secret matches a shared secret stored in the memory of the NFC reader device;
• and
• in response to determining that the received shared secret matches the shared secret stored in the memory of the NFC reader device, causing an action to be performed by a device associated with the NFC reader device.
