How much does RFID asset tag cost?

Could you please provide some insight into the pricing of RFID asset tags? I'm interested in understanding the range of costs associated with implementing this technology for inventory and asset tracking purposes. Are there any factors that typically influence the cost, such as the size of the tag, the type of material used, or the quantity ordered? Additionally, is there a difference in cost between passive and active RFID tags? Your expertise in this area would be greatly appreciated.
