Encrypted Smiley Secure Protocol - eSSP

In Python 3

eSSP version : 6

Officialy Support :

• NV200
• NV11
• NV10

Maybe that other models works, but we haven't tested them.

Installation

Over PIP :

pip install eSSP6

or for the latest version ( maybe unstable )

pip install git+https://github.com/Minege/eSSP

Functionalities

• Multi-currency support
• Poll events interaction
• Response data interaction
• Route to storage
• Route to cashbox
• Payout
• Payout next note (NV11 Only)
• Stack next note (NV11 Only)
• Disable the validator
• Disable the payout device
• Reset the validator
• Empty the storage ( Send all storage's bills in the cashbox quickly )
• Get note amount

Running example 1 with a NV200 :

Set to storage 10 CHF and 20 CHF, putting 10 CHF and 20 CHF, and payout 10 CHF and 20 CHF.
