: Write to EPC
Writes to the EPC memory area of a data carrier that was previously selected with the Select
command.
In Single-Tag mode, that is, if only one data carrier is located in front of the active read/write zone
antenna, then the Select command can be disregarded. The
Write to EPC
command will be
automatically executed on the data carrier that is located in front of the antenna.
Note
If the order is executed without the preceding Select and more than one data carrier is
located in front of the antenna, the command will then be acknowledged with the
Multiple-Tags status code.
The EPC can have a length of 2...62 bytes; the number of bytes must be
even.
