Seriously, a chip with no visible control interface? A security risk waiting to happen.
It's in your body? Well, at least we don't have the technology for interfacing with nerves yet... *recalls episode of White Rabbit Project* oh, wait. Kari was controlling Tory's body with things just stuck to his skin... basically a heart monitor, but in reverse. Well, with only one point of contact, rather than having the chips all over your body, you should be safe from having more than occasional spasms in your hand. Though you already hear about pacemakers causing problems when faced with other devices.
It has access to your bank accounts? COMPLETE AND UTTER ALARM BELLS. I don't like anything to have access to my money - I still bank face-to-face with the tellers, for crying out loud, despite my generation being the driving force behind digitizing everything. It's because, more than being social-media-savvy, I'm somewhat actually tech-savvy, and I know how easy it is for a device to be hacked; I know the banks claim their website is safe, but is MY COMPUTER safe? Absolutely not, I already know this. I have to blast viruses every couple months. Heaven knows if my phone is safe. I don't trust it.
So to summarize, it has no control interface and has access to your money, making it a major security risk, and it's an electronic device inside your body, so it could be overloaded to cause spasms or worse.
