Go to your BBVA branch to sign up for an Android POS terminal (if you don't have one yet) and request the Smart Business Lite app.
Search for the app on your BBVA Android POS terminal and try the free DEMO version.
If you wish to sign up for the full payment version by Revo, the supplier of the Smart Business Lite app for BBVA, select the button enabled for this directly from the app.
Or if you wish, go to the Revo page and follow the indicated steps.
