Which USB Dongle License Key Is Worth Your Money? AVEVA, Simplex, Datacard, MICROS

Four USB license dongles range from $10 to $6200. Compare AVEVA, Simplex, Datacard, and MICROS hardware keys by price, condition, and the software they unlock.

Last updated Aug 9, 2026

When your software depends on a physical USB license key, choosing the right dongle is not a casual purchase. These physical license media hardware keys are often tied to a specific application, and a mismatch can leave you with a key that won't unlock anything. The four options here range from a low-priced used dongle to a high-priced new license kit, so the decision is as much about budget as it is about compatibility.

Quick take

  • The AVEVA License Kit is a new hardware key for industrial mining equipment software, making it the highest-priced option in this group.
  • The Datacard ID Works Standard v6.5 kit bundles the software set and a USB security dongle for ID card printing.
  • The Simplex 4120 4100 TSW dongle is a used security key for Simplex fire-alarm software, but the exact program it unlocks is not specified.
  • The MICROS E7 Software License Key is the most affordable option, a used dongle for MICROS E7 systems.

Product notes

Simplex 4120 4100 TSW security software hardware USB dongle key sentinel 741-780

The Simplex key is a used USB dongle priced at USD 1,200.00. It carries the Simplex part number 741-780 and is a security key for Simplex fire-alarm systems. It isn't specified whether the dongle unlocks the Simplex 4100 programmer, the 4120 programmer, the TSW True Site Workstation programmer, or the TSW Runtime operations. If you already work with Simplex equipment and need a key with this part number, the dongle could be exactly what your software expects. The limitation is the lack of a confirmed unlock path, plus the used condition, which means you're taking on uncertainty with a four-figure price.

Datacard ID Works Standard v6.5 Identification Software CD & USB Dongle Key

The Datacard kit is a pre-owned package at USD 699.99 that includes the original case, installation CD, inner setup instructions, and the SafeNet Sentinel USB security dongle needed to activate the software. This is the Standard Edition with advanced ID program capabilities such as open database connectivity (ODBC) and proximity card plug-ins. For someone restoring a Datacard ID printing station, having the physical CD and dongle together is a practical advantage. The drawback is that the whole package is pre-owned and the version is fixed at v6.5, so you're not getting a brand-new license key.

AVEVA License Kit USB Dongle Hardware Key, Software License Key, MPN 100377040

The AVEVA kit is a new, unused hardware key priced at USD 6,200.00. It's labeled for Joy continuous miners, long wall shearers, JOS enclosures, AFCs, loaders, and FCTs, with licensing software for Face Boss 1 operating systems. For an operation running that specific AVEVA licensing environment, a new hardware key is a direct replacement option. The obvious limitation is cost: among these four options, this is the highest price, so it should be reserved for a system that genuinely uses this exact license kit.

MICROS E7 SOFTWARE LICENSE KEY 100074-279 = USB DONGLE

The MICROS dongle is a used USB software key priced at USD 10.00, and it comes from merchant i-UayBiQri. It's designed for MICROS E7 systems. Unless an item is listed as new, it may have cosmetic scuffs or scratches, and the photos show the item's condition. If you have a MICROS E7 system and need a spare dongle at the lowest price, this is the least expensive option in this comparison. The limitation is that it's used, and when multiple items are available, pictures may be representative, so the exact dongle you receive could differ cosmetically.

Final recommendation by use case

If you're outfitting an industrial automation setup with a brand-new license key, the AVEVA License Kit is the one that matches that need, though it demands the highest budget. For a Datacard ID card software installation, the Datacard ID Works Standard v6.5 kit gives you the software media and the required Sentinel dongle. If you're working with Simplex fire-alarm software and need the 741-780 part, the Simplex dongle is the only product here tied to that Simplex part number, but the unspecified unlock path is a major caveat. And for a cost-conscious MICROS E7 user, the MICROS E7 dongle is the least expensive path to a hardware key for an E7 setup.
