Container House Electric Card

The electric card for container houses is usually a smart induction power card, using T5577 or T5557 chips, and needs to be used in conjunction with the smart electricity meter system pre-installed in the house. Here are the specific details:

Electric Card Types and Functions

The electric cards for container houses are mostly smart induction power cards, with common types including:

• T5577 Chip Card: Widely used in hotels, apartments, and other scenarios, supporting induction power extraction. Users can connect the house's power supply by inserting the card and automatically cut off the power by removing it. These cards are available for wholesale on Alibaba, with prices ranging from 0.71 yuan to 4 yuan per card. They have a high repurchase rate (up to 22%) and are mainly produced in Shenzhen and Dongguan.
• T5557 Magnetic Card: Some houses use magnetic card induction power extraction systems, which need to be used with dedicated electricity meters. The price is about 3.8 yuan per card, with a repurchase rate of 13%.
• Composite Card: Some electric cards integrate high and low-frequency functions, serving both as access control and power extraction cards, suitable for scenarios requiring integrated management.

Correlation Between Electric Cards and House Systems

Electric cards need to be matched with the smart electricity meter system pre-installed in the house:

• Prepaid Electricity Meters: Some container houses use prepaid card-inserting electricity meters. Users need to recharge for electricity first and then insert the electric card into the meter to complete the electricity loading. These meters are equipped with IC recharge cards, priced at about 1.71 yuan per card, with a repurchase rate of 17%.
• Postpaid Systems: If the house uses a postpaid model, the electric card may only serve as a power switch, with electricity metering directly uploaded to the management platform by the meter, eliminating the need for users to insert the card for recharging.

Procurement and Adaptation Recommendations

• Confirm the House's Electricity Meter Type: Before procurement, clarify whether the house uses a prepaid or postpaid electricity meter, as well as the card type supported by the meter (such as T5577, T5557, or composite cards).
• Choose a Reputable Supplier: It is recommended to contact suppliers in Shenzhen, Dongguan, and other places through platforms like Alibaba, prioritizing those with in-depth factory inspections and high repurchase rates to ensure card compatibility and stability.
• Bulk Purchase Discounts: The unit price of electric cards decreases with the purchase volume. For example, a T5577 chip card from a supplier in Shenzhen costs 3.33 yuan per card, and further price negotiations are possible for bulk purchases.
