1. A method comprising:
routing, by a merchant center and in response to a first transaction request, merchant data and consumer identification data to the merchant center;
determining, by the merchant center, consumer payment data based on the consumer identification data, and wherein the merchant system does not obtain access to consumer payment data associated with the first transaction request; and
generating, by the merchant center and based on the consumer payment data, a second transaction request comprising the merchant data and the consumer payment data.
2. The method of claim 1, wherein the merchant center includes an APL.
3. The method of claim 1, wherein the merchant data includes at least one of merchant identification data, merchant product data and merchant service data.
4. The method of claim 1, wherein the merchant system includes a virtual point of sale (vPOS).
5. The method of claim 1, wherein determining comprises querying, by the merchant center, a database for the consumer payment data based on the consumer identification data.
6. The method of claim 5, wherein the database is configured to store the consumer identification information and the merchant data received from the merchant system.
7. The method of claim 1, wherein the merchant center is further configured for registering at least one of the consumer payment data, consumer identification data and the merchant data.
8. The method of claim 1, further comprising transmitting, by the merchant center, the second transaction request to the transaction server.
9. The method of claim 1, wherein the merchant data received from the merchant system and stored in the database is inaccessible to a consumer system.
10. The method of claim 1, further comprising transmitting, by the merchant center and to the merchant system, information related to the second transaction request.
11. The method of claim 1, further comprising registering, by the merchant center, the merchant data with the merchant center.
12. The method of claim 1, wherein a virtual point of sale device of the merchant system and an API of the merchant center are linked.
13. A merchant center comprising:
a merchant center processor,
a tangible, non-transitory memory configured to communicate with the processor,
the tangible, non-transitory memory, having instructions stored thereon that, in response to execution by the processor, cause the processor to be capable of performing operations comprising:
routing, by the processor and in response to a first transaction request, merchant data and consumer identification data to the merchant center;
determining, by the processor, consumer payment data based on the consumer identification data, and wherein the merchant system does not obtain access to consumer payment data associated with the first transaction request; and
generating, by the processor and based on the consumer payment data, a second transaction request comprising the merchant data and the consumer payment data.
14. The system of claim 13, wherein the merchant center includes an API.
15. The system of claim 13, wherein the merchant data includes at least one of merchant identification data, merchant product data and merchant service data.
16. The system of claim 13, wherein the merchant system includes a virtual point of sale (vPOS).
17. The system of claim 13, wherein determining comprises querying, by the merchant center, a database for the consumer payment data based on the consumer identification data.
18. The system of claim 17, wherein the database is configured to store the consumer identification information and the merchant data received from the merchant system.
19. The system of claim 13, wherein the merchant center is further configured for registering at least one of the consumer payment data, consumer identification data and the merchant data.
20. An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a merchant center, cause the merchant center to be capable of performing operations comprising:
routing, by the merchant center and in response to a first transaction request, merchant data and consumer identification data to the merchant center;
determining, by the merchant center, consumer payment data based on the consumer identification data, and wherein the merchant system does not obtain access to consumer payment data associated with the first transaction request; and
generating, by the merchant center and based on the consumer payment data, a second transaction request comprising the merchant data and the consumer payment data.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A rotary engine comprising
a housing having a first and second intersecting cavity disposed therein, the first and second cavities including cylindrical wall surfaces;
a rotor rotatably mounted in the first cavity, the housing and the rotor defining an annular chamber disposed therebetween, the rotor including a piston extending from the rotor into the annular chamber;
a first valve rotatably mounted in the second cavity, the first valve having a circumference and recess sized to accommodate the piston during a rotation of the rotor; and
at least one passage comprising an open portion formed in the cylindrical wall surface of the second cavity and an enclosed portion enclosed by the housing along a length of the enclosed portion, the open portion including a leading end and a trailing end with respect to a direction of rotation of the first valve and which open portion extends for at least about 20 degrees around a circumference of the cylindrical wall surface of the second cavity, and wherein the enclosed portion connects the open portion to the annular chamber downstream of the second cavity relative to a direction of rotation of the rotor.
2. The rotary engine according to claim 1 wherein the open portion extends for at least about 90 degrees around the circumference of the second cavity.
3. The rotary engine according to claim 1 wherein the open portion extends for at least about 180 degrees around the circumference of the second cavity.
4. The rotary engine according to claim 1 wherein a distance between the trailing end of the open portion and the intersection of the first and second cavities located on a downstream side of the second cavity with respect to the direction of rotation of the first valve is greater than a width of the recess at the circumference of the first valve.
5. The rotary engine according to claim 4 wherein a distance between the leading end of the open portion and the intersection of the first and second cavities located on an upstream side of the second cavity with respect to the direction of rotation of the first valve is greater than a width of the recess at the circumference of the first valve.
6. The rotary engine according to claim 1 further comprising
a third cavity disposed in the housing and intersecting the first cavity;
a second valve rotatably mounted in the third cavity;
at least one intake port disposed within the annular chamber;
at least one exhaust port disposed within the annular chamber; and
wherein a flow of gases through the intake port and the exhaust port is varied by the second valve.
7. The rotary engine according to claim 1 further comprising at least one fuel injection port opening into the second cavity wherein a fuel may be injected through the fuel injection port into the recess in the first valve.
8. The rotary engine according to claim 7 further comprising at least one ignition port opening into the second cavity and adjacent to an end face of the first valve.
