Access cards & fobs

Access-Card Quantity Calculator

How many access cards or fobs do you actually order? Enter your regular users, a spare-stock buffer, a visitor/temporary pool and an annual loss rate to get the initial order, the replacements you will burn in a year, and the first-year total — so you buy one batch with the same encoding and never run short. Planning figures; runs in your browser.

Tip: order in one batch so every card shares the same encoding and format — and de-commission a card the moment a person leaves. A live card in the wrong hands is a security hole, not a spare.

Planning estimate only — real numbers depend on your turnover and whether you also run PIN, biometric or mobile credentials. Mobile credentials cut physical card use sharply, so adjust the figures to your site and re-order against actual loss records.
