A supermarket in London is trialling a biometric payment system that uses the unique vein pattern in fingertips to pay for goods.
Costcutter said it would consider rolling Fingopay out more widely if the test, at Brunel University, was successful.
An electronic reader maps the user's finger veins, generating a unique key.
But one expert questioned whether biometric systems had any benefit over traditional methods of payment.

exponential function - Feynman's Trick for Approximating $e^x$ - Mathematics Stack Exchange
1. e^2.3 ~ 10
2. e^.7 ~ 2
3. e^x ~ 1+x
e = 2.71828...

errors (absolute, relative):
1. +0.0258, 0.26%
2. -0.0138, -0.68%
3. 1 + x approximates e^x on [-.3, .3] with absolute error < .05, and relative error < 5.6% (3.7% for [0, .3]).

If you ask someone who they are on the Internet, they will likely give you an email address or point to their profile on Twitter, Facebook, Google, or LinkedIn. Some people might instead reference a profile on a more industry specific network such as Behance for creatives or Doximity for doctors. Others use a personal home page provider like and an even smaller fraction have their own domain. This is a pretty unsatisfactory state of the world from both an individual and a service creator perspective.
