Vietnam-Compliant Library RFID Frequency: 918.4–923 MHz

The library RFID frequency in Vietnam must fall within the 918.4–923 MHz band per Circular 08/2021/TT-BTTTT of the Ministry of Information and Communications. Importing UHF RFID equipment that does not operate in this band will make it impossible to obtain a usage license, stalling digital library projects and incurring costs to replace all hardware.

#Why is the 918.4–923 MHz band mandatory for library RFID in Vietnam?

The 918.4–923 MHz band is designated by the Ministry of Information and Communications specifically for RFID (radio frequency identification) applications in Vietnam. Imported UHF RFID equipment must operate within this band, with transmit power not exceeding 500 mW ERP, and must have a Certificate of Conformity before being put into use.

This regulation is set forth in Circular 08/2021/TT-BTTTT on the National Radio Frequency Spectrum Plan, replacing the previous Circular 04/2013/TT-BTTTT. This is a mandatory legal document, not a recommendation. All UHF RFID equipment imported and used in Vietnam, including library management systems, must comply with this frequency band.

Key point: many RFID devices imported from the US or Europe use the 902–928 MHz band (FCC standard) or 865–868 MHz band (ETSI standard). These devices are not compatible with Vietnam's frequency plan, even though they use the same UHF EPC Gen2 technical standard. When bidding, if frequency specifications are not carefully checked, the library may receive equipment that cannot obtain an operating license.

Circular 08/2021/TT-BTTTT stipulates the 918.4–923 MHz band for RFID equipment, maximum transmit power of 500 mW ERP, and requires equipment to have a Certificate of Conformity per National Technical Regulation QCVN 124:2021/BTTTT before being circulated.

The main contents of Circular 08/2021/TT-BTTTT related to RFID:

• The 918.4–923 MHz band is designated for RFID equipment — this is the only band permitted for UHF RFID in Vietnam.
• Maximum effective radiated power (ERP): 500 mW — equivalent to +27 dBm ERP.
• Equipment must comply with National Technical Regulation QCVN 124:2021/BTTTT on RFID equipment.
• The Certificate of Conformity is issued by a designated certification body, based on test results from an accredited laboratory.

Libraries implementing RFID should require contractors to provide a copy of the Certificate of Conformity for each device, along with frequency test results. This is mandatory documentation during acceptance and frequency usage license application.

#How to check if RFID equipment is compliant before bidding?

Check RFID equipment compliance by cross-referencing 4 documents: the Certificate of Conformity, frequency test results, the CR conformity mark on the device, and the datasheet confirming the 918.4–923 MHz band.

4-step verification process:

1. Request the Certificate of Conformity — issued by a certification body designated by the Ministry of Information and Communications. Check that the device name, model, and frequency band on the certificate match the bidding documents.
2. Cross-reference the Test Report — confirming the device transmits within the 918.4–923 MHz band and power ≤ 500 mW ERP. Test results must be from an accredited laboratory (such as Quacert, VNPT).
3. Check the CR conformity mark on the device body — per regulations, compliant equipment must bear the CR (Conformity) mark before circulation.
4. Cross-reference the manufacturer's datasheet — confirming the operating frequency range. If the datasheet states 902–928 MHz or 865–868 MHz, the device is not compliant in Vietnam.

In the bidding documents, clearly state the condition: "Equipment must have a Certificate of Conformity per QCVN 124:2021/BTTTT, operating in the 918.4–923 MHz band." This helps eliminate contractors offering non-compliant equipment from the technical evaluation stage.

#What risks occur if a library uses RFID equipment on the wrong frequency?

RFID equipment on the wrong frequency will not obtain a frequency usage license, will be ordered by regulatory authorities to cease operation, and the library may face administrative penalties under Decree 113/2022/NĐ-CP.

Specific risks of using RFID equipment outside the 918.4–923 MHz band:

• Inability to obtain a frequency usage license — the Radio Frequency Department will refuse to license equipment outside the planned band.
• System shutdown — if detected during inspection, equipment must be completely turned off, disrupting library operations.
• Administrative penalties — under Decree 113/2022/NĐ-CP, using unlicensed transmitting equipment is fined 20–30 million VND, and equipment is confiscated.
• Total loss of investment costs — RFID tags, readers, and security gates already installed cannot be used and must be fully replaced.
• Interference with other equipment — devices transmitting outside the regulated band can cause interference to nearby telecommunications and mobile systems.

When preparing project documentation, libraries should allocate budget and time for obtaining the radio frequency usage license, issued by the Radio Frequency Department. This procedure typically takes 3–5 working days after the application is complete.

#Summary table of library RFID frequency regulations in Vietnam

The table below summarizes the key parameters for compliant library RFID in Vietnam: frequency band 918.4–923 MHz, max power 500 mW ERP, standard UHF EPC Gen2, and mandatory certification QCVN 124:2021/BTTTT.

Note: The technical standard UHF EPC Gen2 is the same across regions, but the frequency band differs. Equipment must be configured to operate in the 918.4–923 MHz band to be compliant in Vietnam.

#What to note when bidding for a library RFID system?

When bidding for a library RFID system, include mandatory requirements: Certificate of Conformity per QCVN 124:2021/BTTTT, frequency band 918.4–923 MHz, and a commitment to support license application. Evaluate contractors based on compliance documentation, not just price.

Key considerations for the bidding process:

• Specify the frequency band in technical requirements — state clearly "918.4–923 MHz" in the technical specifications, not just "UHF RFID". This prevents contractors from offering FCC or ETSI band equipment.
• Require compliance documentation — ask for the Certificate of Conformity, test report, and CR mark photos in the bid evaluation stage, not after award.
• Include license support in the contract — the contractor should assist with the frequency usage license application as part of the project scope.
• Verify tag-reader compatibility — ensure tags and readers operate in the same band and are tested together before acceptance.
• Plan for acceptance testing — include a frequency measurement step during acceptance to confirm actual operating parameters.

In the evaluation criteria, weight compliance documentation heavily. A bid with non-compliant equipment may be cheaper but will fail during licensing, causing project delays and additional costs.

#Common mistakes when selecting library RFID frequency

Common mistakes include assuming all UHF RFID equipment is the same, not checking the frequency band in the datasheet, and relying on the contractor's claims without verifying compliance documents.

Frequent errors in library RFID projects:

• Assuming "UHF" means compliant — UHF RFID has different frequency bands per region. "UHF" alone does not guarantee compliance with Vietnam's 918.4–923 MHz band.
• Not checking the datasheet — many devices are configured for FCC (902–928 MHz) or ETSI (865–868 MHz) bands. The datasheet must explicitly state 918.4–923 MHz.
• Trusting the contractor's verbal assurance — always request written compliance documentation, not just verbal claims.
• Ignoring the license requirement — some projects skip the frequency license application, risking penalties and system shutdown.
• Choosing the cheapest bid — low-cost bids often use non-compliant equipment, leading to higher long-term costs.

To avoid these mistakes, create a compliance checklist and verify each item before signing the contract.

#FAQ — Frequently asked questions about library RFID frequency

What is the library RFID frequency in Vietnam?

The compliant frequency band for UHF RFID in Vietnam is 918.4–923 MHz, per Circular 08/2021/TT-BTTTT. Maximum transmit power is 500 mW ERP. Equipment must have a Certificate of Conformity per QCVN 124:2021/BTTTT before circulation. Using the wrong band results in no license and penalties.

Can US-standard 902–928 MHz RFID equipment be used in Vietnam?

No. The 902–928 MHz band per the US FCC standard is not in Vietnam's frequency plan. Using this equipment will not obtain an operating license and is subject to administrative penalties under Decree 113/2022/NĐ-CP. Equipment supporting the 918.4–923 MHz band must be selected for compliance.

Do RFID tags require compliance certification?

Passive RFID tags do not actively transmit, so they do not require separate compliance certification. However, tags must operate compatibly with readers in the 918.4–923 MHz band. When bidding, require contractors to commit to tag readability with the selected reader to avoid risks.

Who issues the frequency usage license for library RFID systems?

The Radio Frequency Department (under the Ministry of Information and Communications) is the authority that issues radio frequency usage licenses. The application includes a license request form, equipment Certificate of Conformity, and technical documents. The procedure typically completes within 3–5 working days after the application is valid.

How much does it cost to obtain an RFID frequency license?

The fee for a radio frequency usage license is regulated by the Ministry of Finance, typically a few hundred thousand VND for low-power RFID equipment. However, if equipment is non-compliant, the cost of full replacement can reach hundreds of millions of VND.

How to distinguish compliant and non-compliant RFID equipment?

Check 4 factors: (1) Certificate of Conformity issued by a designated organization, (2) test results from an accredited laboratory, (3) CR mark on the device body, (4) datasheet stating the 918.4–923 MHz band. Missing any factor means the equipment is not permitted for circulation in Vietnam.

Does HF RFID at 13.56 MHz require a frequency license?

HF RFID equipment at 13.56 MHz (ISO 15693, ISO 14443 standards) falls within the industrial, scientific, and medical (ISM) band and does not require a separate frequency usage license. However, the read range is only 10–50 cm, suitable for counter checkout but not for wide-area security gates.
