There are no spend functions with run IOTA paper, it is designed to only receive IOTA payments, with separation between Seed owner and people (staff) with permission to view the transfers on the Seed.

The app generates Two separate wallets…

The Master Digital wallet simply provides access to the Seed, password encrypted and compiled to a self contained html file, run anywhere, no internet required or wanted. The Slave / View wallet provides ledger access to view the Addresses on the seed, Also encrypted to reveal a predetermined number of Addresses generated… This wallet has no need for the Seed, just Addresses… the wallet will enable to attach them and start receiving IOTA, view, and export all transfer data.

It is strongly recommended to use separate passwords for the Master and Slave wallets even if for solo use.

A basic simple use case scenario: a boss generates Master and Slave wallets, keeps master (Seed) and gives Slave (Viewer) wallets to Accounts and Sales departments safe in the knowledge that Seed access is never given out, each department can use the viewer wallet to access all transaction data on the Seed.

Built with security in mind, the app has is no Internet access and it disallows keyboard use around seed (key logger safe), it also does not persist to disk (apart from the encrypted wallets that you generate). Lastly there is also a Secure delete function which overwrites randomised data (Trivium cipher) before deletion of wallets not wanted on the device.
