E-Signatures (Baptism and Baby Blessing)

Has anyone used E-Signatures for baptismal records and/or baby blessings? Seems like the process could get a lot more efficient if done this way?

Assuming you mean for the parental authorization to create a child membership record and record the ordinances, where do you see anything allowing, supporting, or facilitating using E-signatures?

The E-signatures I have had to deal with (employment and government related) have required a lot of infrastructure that would have to be set up by Church headquarters. As far as I'm aware, Church headquarters allows only ink-on-paper signatures.

Full-time missionaries use e-signatures for their baptismal forms, where the parent signs on the missionary's phone.
