Keypad vs Card Access Control explains a decision that can materially affect security, safety and administration. Use it to prepare for a site assessment, then have the final design checked against the building, door and operational requirements.
A PIN is remembered; a card is individually issued
A keypad can grant access from knowledge alone. A card or fob presents a physical electronic credential that can be assigned and revoked individually. Either can be shared improperly, but shared PINs make attribution and selective removal especially difficult.
Compare lifecycle and behaviour
| Question | Keypad | Card or fob |
|---|---|---|
| What does the user carry? | Nothing, but must remember and protect a PIN. | An issued credential that can be lost, forgotten or loaned. |
| How is one leaver removed? | Individual PINs permit removal; a shared code may need changing for everyone. | Disable the named credential without replacing others. |
| Can events identify a person? | Only if PINs are unique and not shared. | Events identify the credential; policy and investigation establish who used it. |
| What is the common misuse? | Watching, sharing or writing down a code. | Tailgating, lending or delayed reporting of loss. |
| Administration | Code issue, change and forgotten-PIN process. | Stock, encoding, issue, replacement, return and disposal. |
Use the user population to decide
Small internal room: a stable group uses a low-risk storeroom and individual attribution is unnecessary. A managed keypad may be reasonable.
Staff perimeter door: employees and contractors change, lost access must be revoked promptly and event history is useful. Individually issued cards or fobs usually create a cleaner lifecycle.
Higher-assurance room: supported card-and-PIN may add a factor, but only if PINs are individual, the platform implements the mode correctly and exception procedures do not undermine it.
Plan the change from a shared code
Inventory users, issue named credentials, set an expiry for temporary exceptions and communicate lost-card reporting. Remove or change the old shared PIN after the transition; leaving it active preserves the weakest route. Keep a non-discriminatory alternative for authorised people who cannot use the normal method.
