Identiv here means desktop smart card readers for contact and contactless cards. The uTrust 4701 F handles both in a single unit, reading contact chip cards and contactless cards from the same reader. The uTrust 3700 F is contactless only, so it suits sites that have settled on one card type rather than a mix.
Choosing between them comes down to what your cards already use. If your setup involves chip-and-contactless cards or you expect to run both, the dual-interface 4701 F saves you keeping two devices on the desk. If everything is contactless, the 3700 F does the job without paying for the contact side. Both connect to a workstation for enrolment, verification and encoding tasks. If you are unsure which reader matches your existing cards or software, tell us what you are running and the team at Plastic-ID.com will confirm the right fit before you order.
Identiv uTrust smart card readers are USB desktop readers that plug into a computer. A card can then log a user in, authenticate a transaction or be read into access control or card management software at an enrolment desk. The uTrust 3700 F reads contactless cards on its own. The uTrust 4701 F is a dual-interface reader that reads contactless cards and contact chip cards through a single unit. That contact chip interface is the difference between them.
Both work at 13.56 MHz on the contactless side, the frequency behind MIFARE, DESFire and NFC credentials. That covers the tap-to-read cards most UK organisations issue for logon. Neither reads 125 kHz proximity cards such as EM4200 or EM4305. If the cards on your site are low-frequency prox, a 125 kHz reader is what you need. Tell us the card type you hold and we will confirm compatibility with your specific reader technology before you order.
Pick the uTrust 3700 F when every credential on site is contactless. It keeps the desk setup simple at reception or on a shop floor. The uTrust 4701 F earns its place where a mix of card types is in use. It also suits a card that carries gold contact pads as well as a contactless aerial, where one device must read either interface.
Both are ordered as individual readers. Plastic ID can talk through which reader fits your setup, alongside the cards, ribbons and accessories that go with it. Call or email the team and we will point you to the right one.
