ive seen quite a number of interesting cryto gadgets - one of them was a credit card / debit card looking device - although it had a computer screen on it and required a finger print held on a power button to even use - VERY interesting stuff ; i very much would love to get into this with even greater detail although im a big noob when it comes to things like that - although i have very great math skills ; i feel like i would catch on very quick .
if anyone would like to let me know more information - follow for followw ?!
