RFID Commands
This section describes all of the RFID-specific commands that are used to select tag ID’s, and read and
write on-board tag data.
GET_TAG_ID (01h)
Description
Returns the tag ID of the first tag found in the RF field. Note that tag data is not retrieved, only the
unique tag ID.
Parameters
Tag id
Unique tag identification number. The least-significant byte (LSB) of the tag id is sent first. Note:
when developing a driver library, the byte order for the tag ID should be reversed before passing the
tag ID back to a user application (as the standard method for printing and displaying the tag ID is in
MSB order).
Returns
A GET_TAG_ID packet containing tag ID of tag in the read field, or NACK if no tags are present in the
field.
