The headline's a little bit misleading. They weren't asked, would they give blood? - and I suspect the numbers saying yes would be tiny if they were.

What they were asked about was non-invasive blood-vessel pattern biometrics. There's no particular reason to worry about that technology, which has some advantages over the commoner fingerprints and iris scans. However all such manufacturer surveys need to be treated with caution as measures of public opinion, since they usually are seeking assent to some proposition, rather than looking at unprompted or knowledge-based preferences or realistic options.
