Data Protection and Security-Enabling features
Rev. 1.3
mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet
4.1.4 Unique Identification (UID) Number
Each mDOC H3 is assigned a 16-byte UID number. Burned onto the flash during production, the
UID cannot be altered and is worldwide unique. The UID is essential for security-related
applications, and can be used to identify end-user products in order to fight fraudulent
duplication by imitators.
4.1.5 One-Time Programmable (OTP) Partitions
OTP feature is implemented on a per-partition basis, for full flexibility. Once a partition has been
defined as OTP (upon initial media-formatting), it can be written only once, after which it is
automatically and permanently locked. After it is locked, the OTP partition becomes read only,
just like a ROM device.
Regardless of the state of any of the LOCK options, OTP partitions cannot be erased.
Typically, the OTP partition is used to store customer and product information such as: product
ID, software version, production data, customer ID, PKI keys, service provider information and
tracking information.
