Would you recommend using UHF tags for this application?

Juan,

Writing to a tag, in particular, takes some time, so I would not recommend writing to a tag that is moving, for example, through a toll-collection gate. It would be better to have the car stop, write data to the tag and then have the vehicle proceed again. (If any of our readers disagree and can recommend a tag that might work for this application, they are invited to post information below. Thank you.)

We have published a number of articles about passive UHF RFID tags on moving vehicles being read, but not written to. See the following examples for more information:
