Chapter 6 · Approver

Read the sentence. Sign it.

The amount and the payee are inside what the signature covers, so neither can change afterwards.

This chapter starts where chapters 1–5 leave off. Catch up in one go: the steps that are not signatures run for you, and your device asks twice — the same signatures those chapters make.
