Fine with me. Who is gonna steal my finger to pay? Actually, I want to keep my American Express Membership Rewards Card...I like earning free airline flights. :)
Do you want to know the answer to that question? Kids have been killed for tennis shoes. Killing you to get a finger as a means of wholesale access to your electronic accounts is a much better payback than a pair of fancy tennis shoes.
If you are lucky, you'll just loose the finger to a miscreant with a PVC pipe cutter and a desire to go shopping.
