GeminiRFID Demo Application 5 - 11
Program Tag
This option can be used to program Gen2 RFID tags. 
Gen2 tags can be programmed, erased, locked and killed. Each tag contains 88 or 120 bits, which includes the 
EPC number (64 or 96 bits), CRC, and Kill Code. Locking, and killing tags requires a Kill Code which is 1 byte (8 
bits) long. Since a tag has a very small Kill Code and can be thwarted with many lock/kill attempts, it shuts down 
after a failed attempt for a extended amount of time (possibly up to 10 hours). In addition, data can be collected by 
decoding in-range EPC RFID tags that beam back to the mobile computer the information they contain.
To program RFID tags:
1.
Tap 
 in the main Tags window or tap Mode - Program Tag.
 Figure 5-8    
RFID - Tag Programming Window
2.
Select the Class: 1 radio button to program tags.
3.
In the Tag ID (Hex string) text box below Class:, enter an 8-byte (64 bits) or 12-byte (96 bits) hex string to be 
programmed into the tag. This string can contain any number from 0-9, and a letter from A-F. Each byte must 
consist of 2 characters. Each byte should be separated by a space character.
For example, if the tag should contain 80012390AAFD3617, type 80 01 23 90 AA FD 36 17 as shown in 
.
4.
Set the write strength by moving the Write Att: (attenuation) slide bar to a value in a range between 0 (full write 
power) and 255 (low write power/off).
5.
A password is required to lock a tag and kill a tag. In the 0x: Lock/Kill Code text box, enter a hex lock/kill 
password code. 
6.
Tap Program Tags. It might take more than one attempt to program the tag.
7.
When a tag is successfully programmed, a status message displays in the Status Message text box.
8.
Tap Read to read a newly programmed tag.

Remember the lock/kill code. Once a tag is locked, it cannot be killed without the lock/kill code.
