Clone EM4100 Tag to T5577

What you will need:

1. Connect your Proxmark3 to your computer.

2. Launch the Proxmark3 client. If you do not have the Proxmark3 client setup check out our Getting Started Guide.

3. Once connected to the client run the ‘hw ver’ command. You should see output similar to what is below. If the version is not v3.0.1 your steps and commands may differ from the ones below.

4. Connect an LF Antenna to the Proxmark3 and run the ‘hw tune’ command in the client. You should see output similar to the one below.

proxmark3> hw tune

5. Place the EM4100 Tag on the LF Antenna. Run the ‘lf em4x em410xdemod 1’ command. Take note of your TAG ID. The TAG ID in this example is 1c003ca6ee.

proxmark3> lf em 410xread 1
#db# DownloadFPGA(len: 42096)          
#db# EM TAG ID: 1c003b3717 - (14103_059_03880727)          
#db# Stopped

6. Remove the EM4100 Tag and place the T5577 Card on the LF Antenna. Run the ‘lf em4x em410xwrite 1’ command. Replace with the Tag ID you noted in step 5.

proxmark3> lf em 410xwrite 1c003ca6ee 1
Writing T55x7 tag with UID 0x1c003ca6ee (clock rate: 64)

#db# Clock rate: 64          
#db# Tag T55x7 written with 0xff8f0001b14677bc

7. Test that the tag is working correctly by running the ‘lf em4x em410xdemod 1’. Your Tag ID should now match your previous EM4100 Tag.

proxmark3> lf em4x em410xdemod 1
#db# EM TAG ID: 1c003ca6ee - (42734_060_03974894)
