Technical challenges |
Despite their wide application, flexible electronic tags still need to solve the following problems: |
Cost issues: Large-scale production reduces unit prices (currently 3-5 times more expensive than traditional tags). |
Endurance: Passive RFID tags rely on readers for power supply, and active tags require thinner batteries. |
Durability: Stability of conductive materials after repeated bending (such as the risk of silver nanowires breaking). |
The diverse applications of flexible electronic tags are driving the transformation from 'static identification' to 'dynamic interaction', and may be further integrated with biosensors and energy collection technologies (such as light power supply) in the future. |

Technical details of dynamic barcodes? |
Dynamic Barcode is a barcode technology that can update content or status in real time. It combines traditional encoding, cloud data interaction and encryption technology, and is widely used in payment, logistics, anti-counterfeiting and other fields. The following are its core technical details: |
1. The core principle of dynamic barcode |
Dynamic barcode does not physically change the graphics, but realizes dynamic content through 'encoding + cloud linkage': |
Static part: The barcode itself stores a fixed ID or URL (such as UUID or short link) as a data index. |
Dynamic part: After scanning, the device obtains the latest information (such as payment amount, logistics status) from the cloud in real time through the ID/URL. |
Key difference: |
Traditional barcode: fixed content (such as product GTIN). |
Dynamic barcode: variable content (such as Alipay payment code refreshes every minute). |
|
2. Technical implementation process |
Take the payment scenario as an example (such as WeChat dynamic payment code): |
Generation phase: |
User initiates a request ? Server generates a unique ID and associates the user account. |
The encoder converts the ID into a barcode (such as a QR code) and sets a refresh policy (such as 60 seconds expiration). |
Scanning phase: |
The barcode scanning device reads the ID in the barcode and requests verification from the cloud. |
The server verifies the ID validity, timeliness, and associated data (such as account balance). |
Update phase: |
If the barcode expires, the server rejects the transaction and triggers the client to generate a new barcode (key rotation). |
|
3. Key technical components |
(1) Encoding and data storage |
Lightweight encoding: Use short strings or encrypted hashes (such as Base64-encoded 12xYz8@3) as cloud indexes to reduce barcode density requirements. |
Data separation design: The barcode only contains a key or URL, and the real data is stored in the cloud (such as AWS DynamoDB or Alibaba Cloud Table Storage). |
(2) Real-time communication protocol |
WebSocket/Long Polling: The client maintains a long connection with the cloud to ensure that the barcode status is synchronized in real time (such as the logistics code changes from 'in transit' to 'received'). |
Low-latency response: CDN edge computing nodes process requests nearby (such as Alipay payment code response within 100ms). |
(3) Security mechanism |
Dynamic key rotation: |
Each barcode is bound to a one-time key (such as TOTP time-based OTP), which becomes invalid after expiration. |
Example: The dynamic verification code of Google Authenticator works in a similar way. |
Encryption and anti-replay attack: |
Use AES-256 or SM4 to encrypt data transmission to prevent middleman tampering. |
The server records the barcode IDs that have been used to prevent repeated scanning (such as movie theater e-tickets). |
(4) Graphic generation optimization |
Fault tolerance and refresh balance: |
Even if part of the graphic is damaged (such as 30% occlusion of the QR code), it can still be decoded by the Reed-Solomon error correction algorithm. |
Keep the graphic structure stable during dynamic updates (to avoid scanning failures caused by frequent changes). |
|
4. Technical adaptation of typical application scenarios |
(1) Dynamic payment code (such as Alipay/WeChat Pay) |
Technical points: |
Short validity period (usually 60-120 seconds) to reduce the risk of fraud. |
Two-way authentication: The scanning device needs to have a two-way encrypted handshake with the payment platform. |
(2) Logistics tracking code (such as FedEx smart label) |
Technical points: |
The barcode is linked to the cloud database, and the real-time location, temperature and humidity records are displayed after scanning. |
Permission classification: The recipient only sees the logistics status, and the warehouse staff can view the detailed route. |
(3) Anti-counterfeiting dynamic code (such as Moutai blockchain anti-counterfeiting) |
Technical points: |
After the first scan, it is marked as 'queried' to prevent counterfeiters from querying multiple times. |
Combined with the blockchain to store hash values, ensure that the traceability data cannot be tampered with. |
|
5. Frontier technology evolution |
AI-driven dynamic graphics: |
Generate variable pattern barcodes through GAN, which are difficult for the human eye to detect the difference but can be recognized by the device (experimental stage). |
No network pre-authorization: |
Based on edge computing, some logic is executed locally (such as pre-generating a limited number of dynamic codes when offline). |
Biometric binding: |
The user's fingerprint/facial feature hash value is integrated when the dynamic code is generated, and the secondary biometric verification is performed when scanning. |
|
6. Challenges and limitations |
Network dependency: Cannot be updated without a network (need local cache emergency plan). |
Performance bottleneck: High concurrency scenarios (such as Double 11 payment) require distributed database support. |
Compatibility: Old barcode scanning devices may not be able to parse high-density dynamic codes (need to downgrade to compatible mode). |
The essence of dynamic barcodes is the integration of 'physical identification + cloud services', and its technical core lies in the balance of lightweight encoding, real-time communication and security mechanisms. With the popularization of 5G and edge computing, millisecond-level updates and offline dynamic verification may be further realized in the future. |
