Action may be required before university moves to contactless‑only Purdue ID cards

In addition to door access, we recognize that some campus systems still rely on the magnetic stripe on the Purdue ID Card. These may include KeyWatcher systems, certain time clocks, and localized or legacy door access controls.

For most areas, no. The majority of Transact readers installed since 2013 are dual technology devices that support both magnetic stripe and NFC credentials. Disabling magstripe functionality on these readers does not require hardware replacement and will not disrupt operations. This approach protects prior departmental investments while allowing Purdue to move forward with modern security standards.

Since July 2025, ID Card Operations has replaced any magstripe‑only Transact devices at no cost to departments. Any remaining dual technology devices will have magstripe functionality disabled as part of the migration to the LenelS2 system.

No. Any new devices connected to the Transact or LenelS2 systems must be contactless‑only.

Departments have several options, including:

• Maintaining a limited supply of generic magnetic stripe cards for internal use that are not associated with the PUID number
• Transitioning to systems that support contactless credentials and the encrypted NFC chip
• Exploring alternative authentication methods for systems such as KeyWatcher
• Adopting mobile credentials as a long‑term solution where eligible

For departments that need to retain magstripe functionality for a short period, ID Card Operations can help identify third‑party vendors that produce generic magstripe cards. Departments would be responsible for issuing, managing, and securing those cards independently of the Purdue ID system.

Some campus systems—such as KeyWatcher, older time clocks, and legacy access control devices—may still use magstripe authentication. Purdue does not currently have a complete inventory of these systems.

To identify dependencies:

• Try tapping your Purdue ID card instead of swiping
• If the system only responds to a swipe, it likely relies on magstripe
• Check with your local IT support or building deputy
• Submit questions to transact@purdue.edu for confirmation

Yes. Because there is no centralized inventory, departments must identify and report systems that rely on magstripe technology. Early visibility will allow ID Card Operations to support transitions and help avoid disruptions during the 2026–2027 timeframe.

ID Card Operations will:

• Help identify alternative technologies or compatible hardware
• Provide guidance on NFC‑supported options and mobile credential readiness
• Assist in locating third‑party vendors for short‑term, non‑PUID magstripe cards if needed

There is no central funding for departmental system upgrades or replacements. Departments are responsible for evaluating their systems, funding modernization efforts, and coordinating purchases through procurement.

The Purdue ID Card uses an encrypted NFC contactless chip. Any new hardware intended to work with the Purdue ID Card or Mobile Credentials must support this standard. Departments should consult ID Card Operations for guidance on specifications and vendor options.

Existing physical cards will not have their magnetic stripes disabled. However, after July 1, 2027, Purdue will no longer produce ID cards with a magnetic stripe. All newly issued cards will contain only the encrypted NFC chip.
