Question for those who own an iCopy device: is it anything more than a Proxmark3 RDV4 with a small battery-powered computer running a specialized client, or are there improvements to the Proxmark3 part of it - like better antennae or something?
In other words, if you already have a PM3 RDV4 and you’re happy enough with the regular client, does it bring anything to the table that’s worth buying?
