Keep the capacity measures separate
Face, palm, fingerprint, user and transaction limits describe different resources. For example, MB10-VL lists 100 faces and 500 fingerprints, while D3 lists 500 standard faces with optional expansion. The larger number in one field does not expand another field.
Specify the hardware and reporting configuration
Establish card technology, required wireless connection, power backup and the supported attendance software. K40 identifies SSR as optional in its function list, so a requirement for local spreadsheet reporting must be named in the supplied configuration rather than inferred from a family heading.
