Application of RFID in Bank File Management

I. Practical Dilemmas of Bank File Management

Bank files are the core vouchers of financial businesses, including credit files, accounting vouchers, customer documents, bills & deposit certificates, collateral title deeds, etc. Their management faces unique challenges.

Extremely Strict Security Requirements

Bank files involve customer privacy, capital transactions and credit risks with high confidentiality levels.

Regulatory requirements mandate full traceability of file inbound/outbound and real-time alarms for unauthorized outbound movement.

Traditional manual management carries risks of favor-based borrowing, file loss and information leakage.

Massive Volume with Continuous Annual Growth

A provincial branch of a large bank stores over one million files in the archive repository, with hundreds of thousands of new files added each year.

Retention periods can be as long as 30 years, bringing enormous pressure on warehouse space.

Manual inventory of 1 million files requires 10 staff working for 30 days, with accuracy merely 95%.

File Access Efficiency Restricts Business Operations

File inquiries are frequent for credit approval, audit inspections, regulatory reviews and customer disputes.

The traditional process — submitting application → approval → manual retrieval → registration → borrowing — takes an average of 2 hours.

Emergency services such as court freezes cannot respond promptly, damaging bank reputation.

Escalating Compliance & Audit Pressure

The Banking and Insurance Regulatory Commission, the People’s Bank of China and audit authorities conduct regular inspections requiring complete file circulation records.

Paper records are easy to tamper with or lose, leaving no credible evidence for compliance defense.

File destruction requires dual-person supervision and full video recording, incurring high manual costs.

Core Value of RFID:

Assign an electronic ID card to every file, enabling contactless identification, precise positioning, full lifecycle traceability and real-time monitoring. Upgrade million-level file management from labor-intensive manual work to intelligent standardized control.

II. RFID Application in Seven Key Business Links

Link 1: File Warehousing — Establish Digital Identity at the Source

Scenario Overview

Various business departments (credit, accounting, retail) generate massive files daily for handover to the central archive. Traditional workflows rely on manual handover lists, on-site counting, cataloging and shelving — featuring long procedures, high error rates and poor traceability.

RFID Implementation

1. File Packaging & Tag EmbeddingEach file is placed in a standard file box with an RFID electronic tag attached to the side (13.56MHz HF, 50×50mm).The tag stores core file information:

• File No.: e.g. XD-2025-001234 (Credit File No.1234 of 2025)
• File Type: Credit contract / Accounting voucher / Bill & deposit certificate
• Affiliated Institution: XX Sub-branch / XX Branch Business Department
• Retention Period: 10 years / 30 years / Permanent
• Confidentiality Level: Secret / Confidential / Internal
• Warehousing Date: 2025-04-02

2. Batch Inbound IdentificationStaff push a file trolley holding 50 boxes through the RFID portal gate.Built-in readers and antennas automatically identify all 50 file tags within 3 seconds.The system auto-verifies quantity; exact matching triggers automatic receipt.Quantity discrepancies trigger audible & visual alarms and display missing file numbers instantly.
3. Intelligent ShelvingFile boxes are placed on intelligent compact shelves equipped with built-in RFID antenna boards on each layer.The antenna instantly recognizes the tag once placed; the system automatically records the exact location:Repository 3, Compact Shelf 5, Layer 2, Column 3.No manual location registration required; the system tracks the real-time position of every single file.

Actual Benefits

Warehousing efficiency increased 10 times: counting 50 files shortened from 30 minutes manually to 3 seconds automatically.

Precise location management replaces vague regional positioning, achieving meter-level accuracy.

Link 2: Intelligent Storage — The Intelligent Apartment for Archives

RFID Implementation

1. Intelligent Compact Shelf — Navigation & PositioningThe system displays real-time location (repository – shelf – layer – column) of every file.When searching by file number, the system automatically:

• Electrically opens the corresponding compact shelf
• Activates flashing LED indicator at the exact position
• Displays precise location guidance on screen

Staff retrieve files directly without rummaging; average search time shortened from 30 minutes to 3 minutes.

2. Misplacement AlarmIf a file is returned to the wrong layer or column, the RFID antenna detects mismatched location data:

• Red warning mark displayed for the misplaced file
• Buzzer prompts correction
• System records abnormal operation and alerts administrators

3. Intelligent Environmental MonitoringDeploy sensors for temperature, humidity, PM2.5, formaldehyde and ultraviolet radiation inside the repository.Automatic linkage with air conditioners, dehumidifiers and purifiers when parameters exceed thresholds.Stable long-term preservation environment maintained: temperature 14–24℃, humidity 45–60%RH.

Actual Benefits

3. Automatic Discrepancy AnalysisThe system compares inventory data with warehouse records and classifies results automatically:

• Normal: consistent location and status
• Misplaced: in stock but wrong position with correct location prompted
• Missing: recorded but not found, triggering traceability procedures
• Unregistered: physically present without warehousing records for source verification

Actual Benefits

Inventory efficiency increased by 90% and labor costs reduced by 80%.

Annual inventory completed easily by 2 staff within 2 days instead of company-wide mobilization.

Link 5: File Destruction — The Final Compliance Gate

Scenario Overview

Files reaching retention limits (10 years / 30 years) require appraisal and destruction. Regulatory rules mandate dual-person supervision, item-by-item verification, full video recording and irreversible disposal. Manual verification is inefficient with risks of improper retention or wrongful destruction.

RFID Implementation

1. Automatic Destruction List GenerationThe system screens expired files and generates a destruction list with file number, name, expiry date and retention period.Approval workflow: file administrator → department head → senior leader → bank president.
2. Pre-destruction VerificationFiles pending destruction are placed in dedicated containers and pass through the RFID portal for batch identification.System verifies quantity consistency; exact match permits destruction.Quantity discrepancies trigger immediate alarm and traceability of missing items.
3. Destruction Process MonitoringRFID readers deployed at the destruction site monitor container position in real time.Final tag identification is performed before files enter shredders/incinerators to record destruction time.Tags are destroyed together with files to ensure irrecoverability.
