Its called progress. Who writes cheques these days ? Soon it will be, who carries cash around ? followed by who carries cards around ?
There will always be criminals, ergo there will always be someone after your money whatever mechanism you use. Soon you will be wearing under skin implants and bringing them in close proximity to someone else's to transfer money (yes, i've been reading Iain M Banks (rip) culture book, but find the future tech he describes very plausible).
New technologies will always attract criminals, but that's inevitable. I find all this tech adversity very Victorian.
