What is the best way to identify people: card, fob, phone, PIN or fingerprint?
It depends on what is lost if that credential ends up in the wrong hands, and it is almost never the same answer at the street door as in the server room. The useful question is not which technology is best, it is what happens the day somebody uses it who should not.
Each one has its trade-off and it is worth saying it in full. The card and the fob get lent and get lost, and they are the most convenient and the cheapest to replace. The PIN can be given out over the phone, so more people know it than are on the list. The phone hardly ever gets lent because nobody hands over their phone, and it runs out of battery. The fingerprint does not get lent, and in exchange it drags a serious legal problem behind it and does not work with gloves or with very worn hands. The number plate identifies the car, not the driver.
The rule that works is duller than the technology: one credential per person, in that person's name, and two factors only on the doors where the risk justifies it. What we have seen since 2006 is that these systems rarely fail on the credential technology. They fail because nobody takes people off the list.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
