Advanced Card Systems Ltd. — MAC prefix 00:23:2F identifies a registry assignment
Summary
- // what this is
- Advanced Card Systems is registered to MAC prefix
00:23:2Fin the IEEE OUI database. When a device's MAC address begins with00:23:2F, that block was registered by Advanced Card Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible suffix values; this is not a device or shipment count. For the exact literal prefix 00:23:2F, the first-byte Group and Local bits are both 0. Changing either bit changes the prefix. The assignment does not establish product use, deployment, traffic prevalence, current legal identity, or security state.
About this vendor.
A MAC address beginning 00:23:2F matches an IEEE MA-L assignment to Advanced Card Systems Ltd.; that match identifies the registered organization, not a specific device or product. The supplied evidence does not map this prefix to a device category or to any ACS product.
The company describes itself as a supplier of PC-linked smart card readers and says it develops smart card reading and writing devices, smart cards, and related products. Its WalletMate II Mini is an NFC reader module for mobile wallet applications, but no supplied evidence connects that product to this prefix.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values, not an observed device or shipment count. The first byte 00 has Group bit 0 and Local bit 0. These bits are fixed for an exact literal prefix match; changing either produces a different prefix. RFC 7042 explains the Group and Local bit interpretation for MAC identifiers.
