Method and apparatus for payment transactions
A contactless card reader system comprises the a contactless card reader for short range wireless communication with a payment device using a contactless card protocol. The reader also comprises a terminal for exchanging data with the payment device and with a remote server to perform a contactless card transaction. The terminal is comprised in a personal computing device. The remote server may provide functionality to the terminal in performance of the transaction. A method of performing a transaction is also described.
1. A contactless card reader system comprising:
a contactless card reader for short range wireless communication with a payment device using a contactless card protocol, wherein said contactless card reader includes therein a protected execution environment, which is a physically secured environment within the contactless card reader that is separate from other components within the contactless card reader, that (i) includes at least a protected environment processor and a protected environment memory and (ii) is configured to run a contactless protocol kernel that provides for contactless protocol compatibility; and
a terminal for exchanging data with the payment device and with a remote server in order to perform a contactless card transaction, wherein the terminal is comprised in a personal computing device.
2. A contactless card reader system as claimed in claim 1 , wherein the personal computing device is one of a personal computer, a tablet computer and a laptop computer.
3. A contactless card reader system as claimed in claim 1 , wherein the contactless card reader is integrated with the terminal in a single device.
4. A contactless card reader system as claimed in claim 1 , wherein the contactless card reader is provided as a separate device to the terminal.
5. A contactless card reader system as claimed in claim 4 , wherein the contactless card reader is a dongle attached to the terminal.
6. A contactless card reader system as claimed in claim 1 , wherein the contactless card reader comprises a wireless chipset and an antenna.
7. A contactless transaction system, comprising:
a contactless card reader for short range wireless communication with a payment device using a contactless card protocol, wherein said contactless card reader includes therein a protected execution environment, which is a physically secured environment within the contactless card reader that is separate from other components within the contactless card reader, that (i) includes at least a protected environment processor and a protected environment memory and (ii) is configured to run a contactless protocol kernel that provides for contactless protocol compatibility;
a terminal for exchanging data with the payment device and a remote server for performing a contactless card transaction,
wherein the terminal is comprised in a personal computing device, and the remote server is configured to provide at least a part of a transaction functionality to the terminal.
8. A contactless transaction system as claimed in claim 7 , wherein the server provides some or all of a transaction application used to exchange data with the payment device.
9. A contactless transaction system as claimed in claim 7 , wherein the server provides a database for configuration data.
10. A contactless transaction system as claimed in 7 , wherein the server provides a firewall to protect other systems.
11. A contactless transaction system as claimed in claim 7 , wherein the contactless transaction system is adapted to perform in accordance with EMV protocols.
12. A method of performing a contactless transaction with a payment device, comprising:
contacting the payment device to a contactless card reader by short range wireless communication using a contactless card protocol, wherein said contactless card reader includes therein a protected execution environment, which is a physically secured environment within the contactless card reader that is separate from other components within the contactless card reader, that (i) includes at least a protected environment processor and a protected environment memory and (ii) is configured to run a contactless protocol kernel that provides for contactless protocol compatibility;
running, by said protected execution environment of said contactless card reader, a contactless protocol kernel; and
exchanging data, by the payment device exchanging with a terminal and the terminal communicating with a remote server, to perform a contactless card transaction, wherein the terminal is comprised in a personal computing device.
