Thanks for the question. We are pleased to inform you that we do offer both of your preferred methods.
1. Event-Attendance Pro - this is a desktop application that is designed primarily to track attendance for your events, classes, or any meetings. It supports RFID and Barcode technologies. We offer this as a license to install locally on your windows desktops or laptops. Please visit http://www.event-attendance.com for more information and pricing.
2. i-Attend On-Premise Edition - The i-Attend platform is offered both as a subscription (monthly/yearly), or as an On Premise. The latter allows you to purchase a license of the software which you then can install on your own network using your servers and database. If interested, I can provide you a quote for this - please email firstname.lastname@example.org.
I hope this information helps you!
