On: Getting a biometric security key right

[iam-TJ]

Thanks for the link - this is an ideal solution to the problem of forgetting to carry, or mislaying, tokens.

I was about to press the Buy button for the McLear payment-enabled ring priced at £89.99

https://mclear.com/product/payment-ring/#

but paused for thought after reading the terms and conditions (it's a PrePay Visa account) and finding this gem:

"Your McLEAR Product(s) will be valid for 24 months from date of registration, after which your Product(s) will no longer be able to make contactless payments or have any funds available into your Account."

and less severe but annoying opt-out not opt-in:

"You can tell us if you don’t want to receive any marketing materials from us in accordance with the GDPR 2018, by emailing dpo@mclear.com."

Well I wasn't linking the payment ring, but rather a smartcard in a ring formfactor. As for payments, you can go this daring route

I realised that, but I was side-tracked by the novelty of the payment ring.

That 'daring route' looks like an ideal project for our maker-space -thanks!

Wait, so the ring just stops working two years later for no reason?

Think of it as a temporary Visa card. It's not under their control.

Oh, so the underlying Visa expires and they have no way to renew the same chip? That sucks.
