Hey guys,
I was wondering whether or not the smartphone wallet app, Softcard (previously Isis Wallet) is from a security standpoint, safe to use.
Being a mainstream wireless payment app, I'm a bit skeptical on the risk of something like this being gleaned similar to a wireless packet, although its using the very short range NFC wireless system. I'm basing this skepticism on the research done by several teams a couple years back at DEFCON on extreme long range RFID and Wireless signal capture and see this technology is not exactly safe only due to range.
I was also wondering whether or not any open source possibilities exist in this technology, if the bump terminals being sent with the new POS systems in stores and restaurants are strictly proprietary APIs.
Thanks,
Jace
