Smart card reader JCR721 – overview of features and functions

7 min

Today we offer for consideration a new model of smart card reader – JCR721 production “Aladdin R.D.”… JCR721 is a professional domestic trusted smart card reader for working with smart cards in a corporate environment, it has a familiar look for the Enterprise segment.

A little about useful properties and body

The body of the reader is made of high quality plastic. There are rubberized feet on the body that prevent sliding on the table surface while working with the device.

The smart card sinks smoothly due to a special microlift mechanism TMthanks to which the smart card reader does not scratch the surface of the card.

Why is it important? When using smart cards in most organizations, it is important that the card does not fail as long as possible as a result of interaction with the card reader. If the contact pad is damaged, the smart card is no longer recognized by the device, a card replacement is required.

In the case of the JCR721 card reader, the contact pad remains intact even after 10,000 connections.

This is how the map and contact pad looks like after 1,000 connections on a conventional reader with sliding contacts

This is how the map and contact pad looks like after 10,000 connections on the JCR721 reader with microlift mechanismTM

Note that the resource of the JCR721 card reader is at least 200,000 smart card connections (instead of 50,000).

Appearance and connection

Smart card reader JCR721 has a plastic case, a cord for connecting to a personal computer. Cord connector for connecting a standard USB 2.0 Type-A. To work correctly on a PC, at least one free USB 2.0 Full-speed (12 Mbps) port is required, the reader can also work with USB 1.1, 2.0, 3.0, 3.1. It is necessary to provide a power supply of 5V ± 0.25V at a current of 300 mA, which must be provided by a working USB port (USB 2.0). For stable operation, a connection to a PC is required without using additional adapters, you can use USB hubs with an external power source, but if the USB hub does not have an external source, then this may not be enough for the reader to work. the USB hub itself provides less than 100mA per port.

Also, the JCR721 reader has a cord for connecting to modern laptops and portable devices with a USB 3.1 Type-C connector.

If we talk about the color of the case, then it can be noted that there are two standard colors, light and dark. The manufacturer allows customizing the case by adding an inscription on the case or a company logo. When ordering, you can determine the type of inscription or logo on the surface of the JCR721 reader – choose either pad printing or laser engraving.

It should be borne in mind that if you choose a black reader for ordering, then not all colors in pad printing will be clearly visible, for example, a black logo on a black case. But in some cases, even this option may be pleasant, a matter of taste.

Also, the manufacturer is ready to discuss the color of the case and the length of the cable for large quantities of batches.

It can be noted, taking into account all these parameters, that the reader is intended for intensive use with any type of contact microprocessor smart cards. Supports work with any contact smart cards (MCU) of the GOST R ISO / IEC 7816-3-2013 Class A, B, C (5V, 3V, 1.8V) standard using the T = 0 / T = 1 protocols. Can be used in GIS systems, APCS, to ensure the security of personal data of the 1st security level, at enterprises of CII (critical information infrastructure), in government agencies, at enterprises of the defense industry, the Ministry of Defense, in banks, multifunctional centers (MFC), service offices , in projects such as “Electronic Identity”, “Electronic Government”, “Electronic Declaration” and many others.

Aladdin R.D. company declares that the reader is a trusted means of working with user data that is or will be stored on smart cards. The reader is designed according to the new FSTEC of Russia Trust Requirements, including for working with state secrets.

If we consider a reader for supporting Memory-cards that worked under I2C (S = 8), 3-wire (S = 9), 2-wire (S = 10), with counter cards previously used in “calling cards”, this support is not available at this stage.

A little more about the advantages of the new smart card reader JCR721

The reader is very fast, it supports all modern smart cards, the real confirmed speed of data exchange with a smart card is up to 625 Kbps. The performance of smart card readers depends on several factors. Factor 1 – the speed of exchange with the host (PC) via the USB 2.0 interface, as well as factor 2 – the clock frequency supplied by the reader to the smart card.

In most readers, this frequency is fixed (usually 4 MHz). Some readers can supply different frequencies from a fixed list (specified in the functional descriptor of the CCID device). There are practically no smart cards operating at frequencies higher than 5 MHz, so the higher the frequency supplied by the reader to the smart card, the more chances that this reader will be incompatible with most of the smart cards available on the market. It is worth distinguishing between the speed of communication with a smart card and the speed when working with a smart card. The latter is made up of the time the command was sent to the smart card, the time the command was processed by the smart card, and the time the response was sent from the smart card to the PC.

The smart card reader JCR721 works with all modern operating systems, including Linux (with all Russian distributions), macOS, Elbrus OS, MS VS, Android, Sailfish / Aurora, on IA-32, IA-64, x86-64 processors , ARM, Elbrus, Baikal and on Microsoft Windows. Also, the reader can be connected to a PC where virtualization tools are used, such as Hyper-V, Citrix XenServer, Virtual Box, VMWare, etc.

The JCR721 reader does not require installation of special application software, the work is carried out through standard PC / SC software interfaces, it is a CCID-compatible device, does not require the installation of special drivers and works immediately when connected to the computer’s USB port (Plug and Play).

It should be noted that in modern versions of Windows, Linux, macOS, MS VS, Elbrus, Android 8 (Oreo), Sailfish Mobile, when connected, the reader in the system should be detected automatically, while a green indicator on its case should light up. These operating systems already have a preinstalled CCID driver and are included in these operating systems. But to work with operating systems of versions of Microsoft Windows XP SP3, the CCID driver can be installed by the administrator from the Microsoft Update Catalog at the first connection to a workstation. Also for the X86 architecture, the CCID driver can be downloaded from the link:

The current list of supported OS, hypervisors, virtual environments and processors can be found on the product page of the manufacturer’s website –

But if the reader is not automatically detected in the system, then one of the possible reasons may be the use of outdated OS versions or Firmware versions (“firmware”) of terminal equipment. To fix the problem, you should register the indicated VID / PID in Info.plis and / or contact the manufacturer of the OS or terminal equipment with this problem.

USB Device Class ID: 0x0B

VID (Vendor ID): 0х24DC

PID (Product ID): 0х0428

For Astra Linux 1.4, Astra Linux 1.5 and МС ВС 3.0, the PC / SC smart card support subsystem and the CCID driver must be installed on the workstation by the administrator before using the reader for the first time, according to the instructions for a specific type of operating system. The work of the reader in these operating systems “out of the box” is not guaranteed.

Many organizations that purchase readers for working with smart cards in their information systems often pay attention to the requirements for the operation of the product.

So, the manufacturer claims the following number of characteristics:

– Climatic version of the device: group 1.1 UHL-4

– Operating temperature: + 25 ± 10 ° С

– Relative humidity: 40% to 60%

– Atmospheric pressure: 96 kPa – 103 kPa (720 – 770 mmHg)

The limiting operating conditions are the parameters:

– Temperature: from 0 ° С to + 70 ° С, at air temperatures above + 30 ° С humidity should not exceed 70%

– Relative humidity: up to 80%, non-condensing

– Atmospheric pressure: 84 kPa – 106.7 kPa (630 – 800 mm Hg)

After transporting the reader at low temperatures and then raising the temperature to normal, moisture condensation may occur, which may cause the reader to malfunction. In this case, it must be completely dried, observing the temperature regime.

The reader is safe for human health and meets the requirements of the Unified Sanitary-Epidemiological and Hygienic Requirements for Goods Subject to Sanitary-Epidemiological Supervision. The certificate of conformity can be found on the manufacturer’s website in the “Additional resources” tab

The reader has increased immunity from breakdown by static electricity (up to 15 kilovolts), does not affect the operation of electronic equipment sensitive to electromagnetic radiation and interference, has increased immunity from electromagnetic radiation and interference.
