Jelly Bean may be all the rage at the moment, but the CyanogenMod team hasn't forgotten about their Ice Cream Sandwich implementation. Tucked in with the newly updated CyanogenMod 9.1 is support for the brand new SimplyTapp near-field communication system. SimplyTap is the labor of love of two dedicated CyanogenMod users, with the aim of broadening NFC payment usage via a more open implementation of the embattled standard. Currently the Tapp app is only compatible with CyanogenMod 9.1 - CM10 is moving a little too quickly to reliably add the necessary code.
Naturally, you'll also need an NFC-enabled device to use the SimplyTapp service.
