RFID NFC Changeable UID (4 byte) 1K Gen1a Magic Sticker for Proxmark3 US SHIP

Description

RFID NFC Changeable UID 1K Gen1a Magic Sticker, 4-byte UID
Sticker is 1 inch/25mm diameter, self-adhesive with waxed backing and a glossy, sort-of-printable top surface.  Laser printing not recommended.
This is a Gen1a Magic device, the UID and Block 0 contents can be changed with Proxmark or other specialized hardware.
Note that this
CAN NOT BE UID CHANGED
with Android MCT App unless you have a rooted phone with capable hardware and some drivers.
If you want a specific UID set, message & I'll write it for you before shipping.  I am unable to accommodate other, more tedious writing requests, but anything outside block 0 can be written with standard tools.
This product is NOT manufactured by, endorsed by or in any way associated with any spammy corporate entities that like to submit VERO takedowns for their trademarks that are already hopelessly diluted, though it does act very much like a classic brand of NFC device with a 1K capacity and a 4-byte UID.
