The second-generation resident id ™entity card of the Peopleδ©σ's Republic of Chin∑≠≈a is a single page card type doc§✔ument made of multiple layers of polyes☆€φter materials, and is produced₹¶ using non-contact IC card↕≠♣​ technology.

Starting from January 1, 20∏ασ‍04, second-generation ≠α φresident identity cards were gr÷✔₹adually issued to Chineβ¥€se citizens. With the prπ✔£×ogress of the replaceme↕×nt work, some related supp§→∑×orting industries wer≈•φ§e also born.

The second generation of ID c∑φ"$ards has six major charac≥‌<teristics: integration of IC card t✘♠★↓echnology, improved anti-counte&ε≥rfeiting performance, shortened prφ‌☆ocessing time, increas •≈'ed storage information, rede'λfined validity period, and expanπ₩ded issuance scope. ≥™✔α It adopts advanced TypeB λΩnon-contact IC card reading tec™≥♠hnology international♦δly, equipped with a dedicat∑$ed identity card secur↔×∑ity control module (SAM) authorized b>÷y * * department. After secure γδ authentication with the de←£<"dicated chip in the second-&♣✘generation resident identit↓←y card through wireless tra ÷÷nsmission, the personal info ​&rmation data in the chipπ™☆ is read out and uploaded to t Ωπ<he computer, and functi™≤ons such as decoding, display, storage≤β∞, query, and automatic ÷±®™input are completed.

To read the information oλβf the second-generation ID card, a £λ₩nationally designated dedicated©×® read-write module must Ω∏be equipped. This read-®♣≥write module can only read the physic÷αal serial number of the second-gener ₹<ation ID card and cannot read the n≤★ame, photo, and other σ information on the card.

The second generation ID c₹®ard reading module can read ×♥the physical card number (serial nΩ★γumber) of the second geneδ♠ration ID card and Mifare card, →≥but cannot read the name, ID•₽ number, native place, ad∏‌dress, photo and othe¥£βλr information in the second generatiγ↓on ID card.

Users do not need to unde↓∏≥®rstand the complex co §™±ntrol commands of RF chips such as RC5™★23, nor do they need to understand the↕™ complex key and access control issues↔↑Ω≈ of second-generation ID cards≠≠/Mifare cards. They only need to♦™ call the simplest command δ→↓$to immediately read the ₹§♣physical serial number of •←✔the card.

Attention: Although the antenna integra₹ ted module has an antenna interfε♠δ♠ace, it is already connected to thα£$e built-in antenna of the mod∞εule. Therefore, in act≠↓§♦ual use, it cannot have any♣σα÷ electrical connecti←©on with the outside, otherwise the m♣∞★‍odule will not work properly¥£.

3.1 UART communication interfa→€★ce:

The power communication inte ♣rface definition of UART interface read-write ᶮmodule is shown in Table ∏©&2.

Table 1 Definition of Pow‌λer Communication Interface

The circuit connecting the UART interfε↕ace read-write module to a gen↓☆eral microcontroller (MCU) is shown in Figure 3-3, and the antenna integrat© ed read-write module does not require'π₩ it  External antenna.

The timing diagram of UART communication between the UART int♦✔erface read-write module and the mσ₹₹icrocontroller connected to the host an↔&d module is shown&nb$↔∞↔sp;in Figure 3-4.

3.3 Connection between S"←plit Module and Antenna

The split module requires an external antenna to functionα≈ε×, and the definition of its antenna in±★β←terface is shown in Table 4.

Table 3 Definition of antenna inter‌∏≠face

The circuit connecting the split module and antenna is shown in Figure 3-8. Cs1, Cs2, Cp1, Cp2, and Rp1≠÷↕ are tuning elements of the a≥βΩntenna, and their parameter§≥÷s are different for each antenna andγπ need to be adjusted accor∏∑ding to the actual situation. The p±↔&→arameters in the figurσ∞→δe are for reference only. &nbs←&↕÷p;(Cp1+Cp2) is general¶→•ly 50pF~200pF, and the ant‌♣¶®enna usually has 1~4 turns. Generally≠✘, the larger the coil area, the fewer↓ λ→ turns are required.

Figure 3-8 Split modul"≤λe and antenna connection

3.4 Auxiliary Output

The module has one aux₽•iliary output port, which can be♥β used to connect LED or buzzer. T→♣£§he host can control the module's ™♣δ★auxiliary output through commands

Turn on (output high lev<'®σel) or off (output low level) to contr♠γ₹ol the on/off of the LED and the b¥β÷eep of the buzzer.  The&n¶πbsp;connection between the module auxiliary outpu∏α₹t and the LED or buzzer is shown in Figure 3-9. The auxiliary output can directly dri&★ve the LED, but cannot dir®≤​ectly drive the buzzeβ  r, so an external transiλ™stor is required to driv♣←®e the buzzer.  When powered on, th•≤≠₽e auxiliary output port defa§"‍₽ults to a low level output.

 Figure 3-9 Module auxiliary₽≠ output control LED or buzzer

3.5 Communication indicator l↕←πight

The module has two commun£©>ication data transmission and receptio✔→n indicator lights. No® ↔☆rmally, the two indicator lights are↔¥δ not on. When the modu÷αle receives data, the green÷γ  reception indicator lφ¶®εight will flash;  When the mod×‌ule sends data externally, the π red send indicator light w→£ill flash.  In addition, when t÷β&he module is powered on, ★©the sending indicatoβ↑×r light will light up for 1 ≈₩♦second and then turn off, indicating t✘§hat the module is working properly.₹σ  By using these two indi₩©↑δcator lights, you ca δ₩n clearly know the status of commu® ↕nication, quickly troubleshoot, anβ↔'d avoid the trouble of using an osc‌♥'illoscope.

4. Communication Protoco‍ ↔l

When the host (referred to as thγ↓e device that communicates wi↓★th the module) communicates with the ₽♠Ω module through UART or SPI interf§±Ω←ace, the "command response" ☆Ω​®method is used. The ho♦↔₹→st sends command data to the modu£¥‍le, and the module execut≠♥es the corresponding action, and ≥α₩ then returns the execution resu$≠lt to the host.  When the host 'π↑communicates with the₹₹§λ module through the Wiegand interface,≥∏ the module will actively read the≠£→ card data and then send the card dat₹↑a to the host through the Wiegand ₩¶✔★protocol. The host only needs t↕•≥ o wait for reception.

The parameters for UART communicat​₽✘σion between the host and mεφodule are: baud rate of 19200bps, 8-bit↔λ data bits, 1-bit stoα↑→&p bit, and no parity check.

4.1 Data Frame Structure

The data frame format is divided i÷←"nto host command data fr&¥®↕ames and module response data fram ♣es.

6. Common fault analy>¥sis

6.1 Failed to open serial port

If the demonstration software pro÷©mpts "access denied" when connectin→π±πg to a module, the re¥&βason is usually that the serial port  >∏has been opened and occupi π​¶ed by other software (such as serial  ←σassistant, access control manage©↔ment software, etc.). Please exit th>≈™‍e software that is occup¥☆→★ying the serial port×α☆, or switch to another serial por$♦&t and try again.

6.2 Unable to communicate with module

If the serial port can be opened but co​ ¥mmunication with the module fails, pl₹γease check and confirm the following i®εtems one by one:

1) Is the selected serial port on the Ωσ software the serial port of the ho★♣↔λst connection module? If a USB-UU" ✘ ART converter is used©£÷, please check the virtual αγ‍$serial port number in t   ™he "Ports (COM and LPT)" item in th£'e System Device Manager;

2) Is the communication data cable '≈∏×between the host and the module i©¶n good contact;  Is the TXD and ≠↕≈ RXD data cable of the seria∑¶l port connected corr∏γ ectly and not reversed; &nbs×α‌p;Is the GND of the h®γφost connected to the GN♣εD of the module.  I↕•f the connection is co♦>βrrect, the green receiving ind€✔πicator light of the module will flash ‌¥when the host sends data. ¶Ω If you only see thπ®€e red sending indicator light fl↑≤ ashing, it should be because ¥§₩the TXD and RXD wires are ₩ ₩reversed. Please swap them over;

3) Is the communication parameter sett♣•ing correct? The correct serial co×≥mmunication parameters should be bau↕→£πd rate of 19200, 8-bit data>&₹ bit, 1-bit stop bit, and no pa<₽rity check bit;

      4) Cheε✘♥ck if there are any errors in the data<δ♦‌ sent, especially pay at♠→₽<tention to whether the ε★♥ checksum is correct.

6.3 Unable to read card serial number

If the host can read the information✘↔©σ of the module (indicatin∞∞☆g that the communicaΩ₹≈®tion between the host and the ₹♣module is normal), but cannot ¥•©×read the serial number of theΩ>≈ card, please check if it is ca☆ used by the following situat㮣ion:

       1)ε ® Is the card too farφ♠₩ from the card reading ant★‍enna (less than 5cm)? Try placing th≈&£e card close to the antenna before α≤₽÷reading;

2) Is there any large area of metal ar©≥ound the card or module antenna (wit<♣'₽hin 5cm)? Large area metal can ♥₽✔←seriously affect card reading. Please  ∞ move the module to an environmen✔'βt without metal before reading;

3) Is the card a Mifare card? Cε>ommon cards on the market i←®₽δnclude ID cards, etc. Due to€♥♠ the significant differe♥∞>nce in their operating frequency and pr₹λΩ inciple, this module cannot support su‍σch cards.
