Video greeting card module

The choice depends on the card dimensions and budget. Common sizes range from 2.4 to 10.1 inches. For standard A5 cards, a 4.3-inch or 5.0-inch screen is the industry standard. Ensure the resolution is at least 480x272 for small screens and 1024x600 for 7-inch screens or larger to maintain visual clarity. Always verify if the screen is IPS (In-Plane Switching) for wider viewing angles and better color reproduction.

Memory capacity typically ranges from 128MB to 8GB. A 256MB memory is usually sufficient for a 1-2 minute high-quality video. For the battery, ensure the module uses a rechargeable lithium battery with a capacity of at least 300mAh to 1000mAh, providing 1.5 to 2 hours of continuous playback. Confirm that the module supports Micro-USB or USB-C for both charging and data transfer.

Since these contain lithium batteries and circuit boards, they must meet CE, RoHS, and FCC certifications for international trade. For the North American market, UL certification for the battery cell is highly recommended. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and a UN38.3 test report to facilitate smooth air and sea freight.

The most common trigger is a magnetic induction switch (video plays when the card opens). Other options include light sensors, motion sensors, or physical push buttons. For high-end marketing kits, you can request multiple buttons to control volume, play/pause, or switch between different video files.

Lithium batteries are classified as Dangerous Goods (DG). Shipping without proper labeling or documentation can lead to customs seizures or heavy fines. Always use a freight forwarder experienced in Battery Shipping and ensure the modules are packed according to IATA/IMDG regulations to prevent short circuits during transit.

Request a Pre-Shipment Inspection (PSI). Key checkpoints include screen dead pixels, speaker clarity (no buzzing), and battery cycle stability. It is advisable to source from verified manufacturers on Made-in-China.com who offer Trade Assurance to protect your payment until the quality is verified.

Focus on the PCBA (Printed Circuit Board Assembly) quality and screen grade. Ask if they use Grade A screens (no defects) or Grade B. Negotiate based on volume tiers; for orders over 1,000 units, you should expect a 10-15% price reduction. Also, clarify the defective rate allowance, which should ideally be below 1%.

To save on labor, ask the supplier to pre-load the video content at the factory. Ensure the video format is optimized (usually MP4 or AVI) to match the module's hardware decoder. If you plan to upload content yourself, confirm the module is 'Plug and Play' compatible with both Windows and Mac OS.
