Access Control for Offices: Cards, Fobs or Mobile Credentials?

April 22, 2026 · SecXpert Resources

When planning access control for an office, one of the first decisions is which type of credential your team will use day to day. Each option has practical trade-offs.

Proximity Cards

Cards are familiar, inexpensive to issue, and easy for staff to use — tap or present the card at the reader. They're a common default for offices of most sizes.

Key Fobs

Fobs work on the same principle as cards but attach easily to a keyring, which some teams find more convenient than carrying a separate card.

PIN / Keypad Entry

A numeric code entered at a keypad can work well for lower-turnover access points or as a secondary method alongside cards or fobs.

Mobile Credentials

Depending on the platform selected, some systems support smartphone-based credentials — reducing the need for physical cards, though this depends on staff smartphone use and the specific access-control platform's mobile support.

How to Decide

  • Team size and turnover. Larger or higher-turnover teams may value the simplicity of quickly issuing and deactivating cards or fobs.
  • Existing infrastructure. If you're integrating with an existing reader system, credential type may already be constrained.
  • Future flexibility. Mobile credential platforms can offer more flexibility for future changes, depending on the system chosen.

Many offices use a combination — for example, cards for general staff access and PIN entry as a backup at a specific door.
