Mobile credentials: your smartphone opens the door

A mobile credential replaces the card, or complements it: it is created remotely, revoked in a few clicks and never gets lost in a drawer. Five solutions, each with its own way of working. SCAP knows them, distributes them and helps you choose.

See the comparisonAsk for advice

How it works

Whatever the solution, the principle is the same: the phone carries a secure credential, which the reader reads over Bluetooth or NFC.

Bluetooth

The reader detects the phone from a few metres away, depending on the setting. It allows hands-free opening, from a pocket or a bag, and remote opening. This is the mode for car parks and gates.

NFC

The phone has to be held a few centimetres away, like a card. The gesture is deliberate, which avoids accidental openings. It works even when Bluetooth is switched off.

QR code

Some readers also read a QR code shown on the screen, for a visitor or a booking for example. The guest does not need an app.

In every case, the phone does not need the Internet to open the door: reading takes place directly with the reader. The Internet is used to create, modify or revoke the credential.

The solutions one by one

How each one is used day to day, what it brings and what you need to know before choosing it.

HID Mobile Access

A Seos credential in the phone, managed from a cloud portal.

How it is used

The administrator creates the user in the HID portal and sends an invitation. The person adds the credential to their wallet (Apple or Google), or installs it in the HID app. With the wallet, there is no app to open to present the phone. Readers in the SIGNO range have Bluetooth and NFC built in and accept Apple Wallet thanks to the ECP (Enhanced Contactless Polling) feature.

Its strengths

  • A very widespread ecosystem: many controllers and software packages already know how to use it.
  • Apple and Google wallets: the user opens without an app.
  • The same readers also read physical badges, for a gradual migration.

Good to know

  • The model is a per-user subscription, for 1 year or 3 years.
  • The reader and the credential must share the same key: a mobile credential only talks to readers from its own key set.

At SCAP: readers 20NS-SEOS, 20NS-SMART and 20NS-STANDARD, and the MID-SUB-T100 (1 year) and MID-SUB-T103 (3 years) licences.

STid Mobile ID

One app, one customisable portal, five ways to open.

How it is used

The administrator creates the virtual cards on the STid web portal, then the user retrieves them in the app (Apple and Android). The user then chooses a mode: badge (present the phone or watch), slide (pass a hand in front of the reader), hands-free, double tap on the phone even in a pocket, or remote. A simple-identifier virtual card is created automatically when the app is installed.

Its strengths

  • The widest choice of opening modes.
  • Portal that can be branded for you, or connected to your tools through a programming interface.
  • Hosted in a GDPR-compliant French infrastructure, with a dedicated server option.
  • Business model: credits are bought once, with no annual subscription according to STid.
  • Readers in the Architect Blue range also read QR codes and DESFire® EV3 badges.

Good to know

  • Bluetooth features are found in the "Blue" versions of the Architect range.
  • Supported protocols range from OSDP and SSCP to Wiegand.

At SCAP: STid Architect range ("Blue" versions on request). Contact us for the part numbers suited to your site.

XPR Mobile ID

An on-premises solution: you keep control of the credentials and the data.

How it is used

The user installs the XPR Virtual Card app (iPhone and Android). In Basic mode, a free card is created automatically: it suits demonstrations and simple access. In Professional mode, the user sends a request from the app, the administrator creates the card with the VC Manager software and sends it back by e-mail or messaging. The card is tied to a single phone. The modes are: hands-free, remote, card and double tap.

Its strengths

  • Works without the cloud: local management, data kept on the customer's premises. Suited to industrial, public or sensitive sites.
  • One-off payment: one credit per virtual card, in packs of 10, 50, 100 or more.
  • The phone is unlocked with Face ID, a fingerprint or a code.

Good to know

  • Bluetooth is used for all modes, NFC only for card mode.
  • A PC with the software and a desktop reader is needed to load the credits.

At SCAP: Xpro Bluetooth readers XPM-MFBT-WO (narrow), XP-MFBT-WO (standard) and XP-K-MFBT-WO (standard with keypad).

LiNEGUARD Access

The badge is tied to the phone number, which makes changing devices simpler.

How it is used

The user receives an invitation by e-mail (link or QR code), installs the free app and activates the virtual badge. Activation is confirmed by a code received by SMS: the badge is tied to the mobile line. There are three ways to open: hold the phone up like a badge, hands-free (for 2-wire bus installations) or remotely from the screen.

Its strengths

  • Change phones without reconfiguring: with the same number, the rights remain. Otherwise, a new invitation is enough.
  • Loss or theft: the number is revoked from the management software. The readers keep no profile.
  • The phone is unlocked with its own lock (code or biometrics); exchanges are encrypted with 128/256-bit AES.
  • GDPR compliance: only an anonymised phone number is stored, with no geolocation.
  • A single phone can hold the badges for several sites.

Good to know

  • For readers with a keypad, "mobile" mode is enabled with a dedicated activation card.
  • The app is designed for LiNEGUARD readers.

At SCAP: Bluetooth activation card FD-010-218, PID + Bluetooth card FD-010-246, and for configuration: FD-LOG (software licence) and FD-KIT-LOG.

MACS: MobileID and MobileAccess

A platform for readers and also for wireless locks.

How it is used

MobileID turns the phone into a credential for badge readers already installed: in the universal version it presents itself as a card; in the per-door version an app shows the authorised doors, which is very useful for delivery drivers. MobileAccess opens battery-powered standalone locks and cylinders, with no wiring: padlocks, lockers, handles. The MACS platform, distributed in France by SCAP, manages both services.

Its strengths

  • One service for readers, locks, lockers and padlocks from several manufacturers.
  • No wiring for MobileAccess: fast installation, lower costs.
  • Works with partner readers you already know (CIDRON, XPR).

Good to know

  • Terms depend on the service chosen: please contact us.
  • The MACS page lists the compatible manufacturers and readers.

At SCAP: discover MACS, comparison of compatible readers, CIDRON VG3 readers KSR-K200509, KSR-K200452, KSR-K200792 and KSR-K200484, QR modules SC9192-SQ and SC9292-SQ.

Which one should you choose?

A few pointers, depending on your situation. We help you decide for your project.

Your situationLook at first

You want to keep your current badges during the transitionMulti-technology readers read both badges and mobile credentials: all the solutions allow this.

Common points to check before you start

The readers

Not all readers read mobile credentials. You need a model with Bluetooth or NFC and the right key set. SCAP checks your installation before any purchase.

The link to the controller

The reader passes the credential to the controller over Wiegand or OSDP. For good security, OSDP Secure Channel is preferable: see the page on securing your installation.

Organisation

Who creates the credentials, who revokes them, what happens when a phone is lost or an employee leaves? The technology is simple; the procedure must be written down.
