Could a heart attack lock down your bank account in Halifax?

Halifax is the town in West Yorkshire where I live, and it also happens to be the name of a well known UK Bank which started life there. Best known on the this side of the pond for TV adverts featuring a friendly chap called Howard Brown, a former customer services representative and sales ambassador for HBOS which owns the Halifax. If recent reports are correct, then before long the Halifax could also gain notoriety for replacing passwords and PIN codes with bio-metrics. Not just any old biometrics mind, none of this old-fashioned fingerprint scanning malarkey for Howard and co; the Halifax wants to verify customer identify using their heartbeat. With wearables becoming the media luvvie dish of the day, and not just in the tech media space either now that Apple is entering the market for fashion conscious hype junkies, the Halifax would appear to be following suit and assuming that customers will be happy to wear an electronic tag. OK, not the kind that some offenders are required to sport but rather a Nymi wristband. I think that not only is that assumption wrong (my elderly mother would certainly not wear one and nor, for that matter, would my punk rocker teenage son) but the Halifax are equally erroneous when it comes to the identity verification side of things as well.
