The contactless transaction terminal includes a processor, a polling signal generator operably connected to the processor, an NFC circuit operably connected to the polling signal generator, and a receiver operably connected to the NFC circuit and to a data recovery circuit that is operably connected to the processor. Also included is a storage device operably connected to the processor. The storage device stores program instructions which when executed cause the processor to generate, via the polling signal generator, short-distance radio signals including at least three polling signals; emit, via the NFC circuit, the at least three polling signals at frequent intervals for detection by a payment-enabled mobile device; receive at least one of a Type A or Type B signal from the payment enabled mobile device; and permit access to at least one of a location or service. ## Claims ### Claim 1 A contactless transaction terminal for interacting with a payment enabled mobile device to permit access to a location or to a service comprising: a processor; a polling signal generator operably connected to the processor; an NFC circuit operably connected to the polling signal generator; a receiver operably connected to the NFC circuit and to a data recovery circuit, wherein the data recovery circuit is operably connected to the processor; and a storage device operably connected to the processor, wherein the storage device stores program instructions which when executed cause the processor to: generate, via the polling signal generator, short-distance radio signals comprising at least three polling signals including a Type A polling signal immediately followed by a first Type B polling signal and immediately followed by a second Type B polling signal; emit, via the NFC circuit, the short-distance radio signals comprising the at least three polling signals at frequent intervals for detection by a payment-enabled mobile device; receive at least one of a Type A or Type B signal, via the NFC circuit, receiver and the data recovery circuit, from the payment enabled mobile device; and permit access to at least one of a location or service. ### Claim 2 (depends on 1) The contactless transaction terminal of claim 1, further comprising an antenna operably coupled to the NFC circuit, and wherein the at least three polling signals are emitted by the antenna at frequent intervals. ### Claim 3 (depends on 1) The contactless transaction terminal of claim 1, wherein the polling signals that are emitted are indicative of a non-retail contactless transaction terminal. ### Claim 4 (depends on 3) The contactless transaction terminal of claim 3, further comprising: a gate control circuit operably connected to the processor; an access gate interface circuit operably connected to the gate control circuit; and an access gate operably connected to the access gate interface circuit; wherein the storage device stores further program instructions which when executed cause the processor to transmit, via the gate control circuit and access gate interface circuit, instructions for controlling opening and closing of the access gate. ### Claim 5 (depends on 1) The contactless transaction terminal of claim 1, wherein the at least three polling signals comprise EMV card proximity coupling device (PCD) polling signals. ### Claim 6 (depends on 1) The contactless transaction terminal of claim 1, wherein the Type A polling signal generated by the processor comprises a Type A polling signal with an AFI (Application Family Identifier), the first Type B polling signal generated by the processor comprises a Type B polling signal with an AFI value of “10” and the second Type B polling signal generated by the processor comprises a Type B polling signal with an AFI value of “00”. ### Claim 7 A method for permitting access to a location or to a service comprising: generating, by a processor of a contactless transaction terminal, short-distance radio signals comprising at least three polling signals including a Type A polling signal immediately followed by a first Type B polling signal and immediately followed by a second Type B polling signal; emitting, by the processor via an NFC circuit operably connected to the processor, the short-distance radio signals comprising the at least three polling signals at frequent intervals; receiving, by the processor via the NFC circuit, and via a receiver operably connected to the NFC circuit and to a data recovery circuit operably connected to the processor, at least one of a Type A signal or a Type B signal, from a payment enabled mobile device; and permitting access, by the processor, to at least one of a location or service. ### Claim 8 (depends on 7) The method of claim 7, wherein emitting the at least two polling signals at frequent intervals comprises utilizing an antenna operably coupled to the NFC circuit. ### Claim 9 (depends on 7) The method of claim 7, wherein the emitted polling signals are indicative of a non-retail contactless transaction terminal. ### Claim 10 (depends on 9) The method of claim 9, further comprising controlling, by the processor via a gate control circuit operably connected to the processor, an access gate interface circuit operably connected to the gate control circuit and an access gate operably connected to the access gate interface circuit, opening and closing of the access gate. ### Claim 11 (depends on 7) The method of claim 7, wherein the at least three polling signals comprise EMV card proximity coupling device (PCD) polling signals. ### Claim 12 (depends on 7) The contactless transaction terminal of claim 7, wherein the Type A polling signal generated by the processor comprises a Type A polling signal with an AFI (Application Family Identifier), the first Type B polling signal generated by the processor comprises a Type B polling signal with an AFI value of “10” and the second Type B polling signal generated by the processor comprises a Type B polling signal with an AFI value of “00.
