How do you pay for RFID?

Excuse me, could you elaborate on the payment process for RFID technology? I'm curious about the various methods that are typically used to finance RFID implementations and the associated costs. Do businesses typically pay upfront for the tags, readers, and other necessary infrastructure, or are there financing options available? Also, how do ongoing maintenance and operational costs factor into the overall payment strategy? I'm trying to understand the financial side of adopting RFID technology and would appreciate any insights you could provide.
