Hi. I'm new. I'm also a computer networking and security professional in my day job. My wife has a Shopify store and we're very interested in the new chip/card reader for POS transactions.
What can you tell me about how secure the bluetooth connection is between the reader and the paired mobile phone/tablet? I want to know that it's secure, unbreakable, safe, non-toxic, etc. against hackers lurking neaby hoping to to steal credit card numbers or transactions or even modify them or enter their own.
Does Shopify have an official statement about security and their reader's use of bluetooth? If not, why would anyone use it in a scary hacker-filled universe full of bad guys who want to steal identities, money, etc.?
