The systems and methods may communicate with a first device via a first communication method over a wireless communication network. The systems and methods may transmit, to the first device via a second communication method, a first sensory pattern representing a first key. In addition, the system and methods may communicate with the first device via the first communication method using the first key. ## Claims ### Claim 1 A method for secure communication between a transmitting device and a first device, the method comprising: communicating with a first device via a first communication method over a wireless communication network; transmitting, to the first device via a second communication method, a first sensory pattern representing a first key, wherein: the first key is a security key; the second communication method is different from the first communication method; and the first key is encoded using a ciphering scheme; determining that a pairing configuration has changed; transmitting, to the first device via a third communication method, a second sensory pattern representing a second key, the third communication method being specified by the configuration, wherein the second key is encoded based on a ciphering scheme specified by the pairing configuration; and in response to determining that the first key matches a third key located on a server, the third key being a secret key: encrypting a message using a fourth key, the fourth key being a public key, and sending the encrypted message to the first device via the first communication method; communicating with the first device via a fourth communication method. ### Claim 2 (depends on 1) The method of claim 1, wherein transmitting the first and second sensory patterns further comprises transmitting, via an optical transmitter, a light pattern to the first device, the first device being located in a container configured to contain the first device. ### Claim 3 (depends on 1) The method of claim 1, wherein the first pattern comprises a pattern representing the ciphering scheme used to encode the first key. ### Claim 4 (depends on 1) The method of claim 1, further comprising acquiring the ciphering scheme from at least one of a remote server or a local storage. ### Claim 5 (depends on 1) The method of claim 1, further comprising acquiring, from the pairing configuration, at least one of the first communication method, the second communication method, or the ciphering scheme. ### Claim 6 (depends on 1) The method of claim 1, further comprising: receiving, from a server, a request to change the second communication method to the third communication method. ### Claim 7 (depends on 1) The method of claim 1, further comprising: receiving a notification from a server to terminate communication with the first device; and deleting the first key from a local storage. ### Claim 8 (depends on 1) The method of claim 1, further comprising: determining a proximity to the first device; and transmitting the first pattern when the proximity is within a predetermined range. ### Claim 9 (depends on 1) The method of claim 1, further comprising: receiving a notification associated with the first pattern; and transmitting the first pattern in response to receiving the notification. ### Claim 10 (depends on 1) The method of claim 1, further comprising: receiving a fraud detection notification; and in response to receiving the fraud detecting notification: communicating with the first device via the first communication method using the second key. ### Claim 11 (depends on 1) The method of claim 1, wherein the first device comprises one of a smart phone, a smart card, a wearable device, an unmanned aerial vehicle, or a medical device. ### Claim 12 (depends on 1) The method of claim 1, further comprising: encrypting a message using the first key; and transmitting the encrypted message to the first device via the first communication method. ### Claim 13 (depends on 1) The method of claim 1, wherein the first communication method comprises radio frequency communication. ### Claim 14 (depends on 1) The method of claim 1, wherein the second communication method comprises communicating at least one of a light pattern, a sound pattern, a thermal energy pattern, or a vibration pattern. ### Claim 15 (depends on 1) The method of claim 1, wherein the first key has a predetermined time of validity. ### Claim 16 (depends on 15) The method of claim 15, further comprising: in response to determining that the predetermined time of validity has lapsed: communicating with the first device via the first communication method using the second key. ### Claim 17 A non-transitory computer-readable storage medium encoded with instructions which, when executed by one or more processors, perform operations comprising: communicating with a first device via a first communication method over a wireless communication network; transmitting, to the first device via a second communication method, a first sensory pattern representing a first key, wherein: the first key is a security key; the second communication method is different from the first communication method; and the first key is encoded using a ciphering scheme; determining that a pairing configuration has changed; transmitting, to the first device via a third communication method, a second sensory pattern representing a second key, the third communication method being specified by the configuration, wherein the second key is encoded based on a ciphering scheme specified by the pairing configuration; and in response to determining that the first key matches a third key located on a server, the third key being a secret key: encrypting a message using a fourth key, the fourth key being a public key, and sending the encrypted message to the first device via the first communication method; communicating with the first device via a fourth communication method. ### Claim 18 (depends on 17) The non-transitory computer-readable storage medium of claim 17, wherein the operations further comprise: determining a proximity to the first device;
