Systems and methods for cloud based pin pad device gateway
A method of processing payment transactions includes receiving a connection request from a client device, determining whether a gateway is available for the client device, creating a connection between the client device and a gateway, the gateway being a previously existing gateway or a newly generated gateway, creating a message filter for the client device on a message bus, listening for messages on the message bus and transmitting the message to the client device by way of the gateway upon finding a message on the message bus matching the message filter.
1. A method of processing payment transactions, comprising:
receiving a message intended for a stateless personal identification number (PIN) pad among a plurality of stateless PIN pads;
generating a gateway storing state information for the stateless PIN pad, including an address of the stateless PIN pad, based on receiving the message intended for the stateless PIN pad; and
transmitting the message to the stateless PIN pad by way of the generated gateway,
wherein the generated gateway is configured to maintain a connection to only the stateless PIN pad among the plurality of stateless PIN pads.
2. The method of claim 1 , the method further comprising:
receiving a connection request from another stateless PIN pad among the plurality of stateless PIN pads;
creating a message filter for the another stateless PIN pad on a message bus;
listening for messages on the message bus; and
upon finding a message on the message bus matching the message filter for the another stateless PIN pad, translating the message from a message bus communication protocol to a communication protocol of another stateless PIN pad.
3. The method of claim 2 , wherein the message filter matches one or more of a message topic, a PIN pad identifier, a recipient identity, and a recipient address.
4. The method of claim 1 , wherein the generated gateway is terminated after the stateless PIN pad associated with the generated gateway disconnects from the generated gateway or is terminated.
5. The method of claim 1 , wherein the generated gateway is among a plurality of gateways, and
wherein the generated gateway is terminated when a number of gateways among the plurality of gateways that are not connected to a stateless PIN pad among the plurality of stateless PIN pads exceeds a threshold.
6. A computer system for processing payment transactions, the system comprising:
a memory having processor-readable instructions stored therein; and
a processor configured to access the memory and execute the processor-readable instructions, which when executed by the processor configures the processor to perform a plurality of functions, including functions to:
receive a message intended for a stateless personal identification number (PIN) pad among a plurality of stateless PIN pads;
generate a gateway storing state information for the stateless PIN pad, including an address of the stateless PIN pad, based on receiving the message intended for the stateless PIN pad; and
transmit the message to the stateless PIN pad by way of the generated gateway,
wherein the generated gateway is configured to maintain a connection to only the stateless PIN pad among the plurality of stateless PIN pads.
7. The computer system of claim 6 , wherein the plurality of functions performed by the processor when executing the processor-readable instructions further includes functions to:
receive a connection request from another stateless PIN pad among the plurality of stateless PIN pads;
create a message filter for the another stateless PIN pad on a message bus;
listen for messages on the message bus; and
upon finding a message on the message bus matching the message filter for the another stateless PIN pad, translate the message from a message bus communication protocol to a communication protocol of the another stateless PIN pad.
8. The computer system of claim 7 , wherein the message filter matches one or more of a message topic, a PIN pad identifier, a recipient identity, and a recipient address.
9. The computer system of claim 6 , wherein the generated gateway is among a plurality of gateways, and
wherein the generated gateway is terminated when a number of gateways among the plurality of gateways that are not connected to a stateless PIN pad among the plurality of stateless PIN pads exceeds a threshold.
10. A non-transitory computer readable medium storing a program causing a computer to execute a method of processing payment transactions, the method comprising:
receiving a message intended for a stateless personal identification number (PIN) pad among a plurality of stateless PIN pads;
generating a gateway storing state information for the stateless PIN pad, including an address of stateless PIN pad, based on receiving the message intended for the stateless PIN pad; and
transmitting the message to the stateless PIN pad by way of the generated gateway,
wherein the generated gateway is configured to maintain a connection to only the stateless PIN pad.
11. The non-transitory computer readable medium according to claim 10 , the method further comprising:
receiving a connection request from another stateless PIN pad among the plurality of stateless PIN pads;
creating a message filter for the another stateless PIN pad on a message bus;
listening for messages on the message bus; and
upon finding a message on the message bus matching the message filter for the another stateless PIN pad, translating the message from a message bus communication protocol to a communication protocol of the another stateless PIN pad.
12. The non-transitory computer readable medium according to claim 11 , wherein the message filter matches one or more of a message topic, a PIN pad identifier, a recipient identity, and a recipient address.
13. The non-transitory computer readable medium according to claim 10 , wherein the generated gateway is terminated after the stateless PIN pad associated with the generated gateway disconnects from the generated gateway or is terminated.
14. The non-transitory computer readable medium according to claim 10 , wherein the generated gateway is among a plurality of gateways, and
wherein the generated gateway is terminated when a number of gateways among the plurality of gateways that are not connected to a stateless PIN pad among the plurality of stateless PIN pads exceeds a threshold.
