Following the successful introduction of cryptocurrency features for this year's Galaxy S10 handhelds, Samsung now plans to add blockcahin-related services to budget and mid-range models, as well. Besides crypto wallets and digital signage apps, Samsung may also add digital identity verification tools in upcoming Galaxy models.

I think these systems might not be secure. Samsung should avail identity verification service from companies like IDMERIT to verify identities and prevent frauds.
