Description
SLE4442 card is a reliable, secure, and versatile choice for applications requiring moderate memory capacity with high security. Its byte-level write protection, PIN code security, and compatibility with standard readers make it ideal for access control, loyalty programs, prepaid systems, and more. For systems requiring enhanced chip performance or backward compatibility, the SLE5542 is a suitable alternative.
SLE4442 card is a kind of contact IC card using the imported Siemens SLE4442 chip, with the advantages of write protection and logic encryption, the company now provides users at home and abroad blank SLE4442 chip card and excellent card printing and custom processing services. At present, this kind of card is mainly suitable for telecom card, IP card, smart card, integrated circuit card, membership card, e-ticket, VIP card, medical, insurance, transportation, school and so on.


SLE4442 card and SLE5542 card
The SLE4442 card upgrade chip is the SLE5542 card, the difference between the two models is only in the production process and production cost, the SLE5542 production cost is much lower than the SLE4442. For the user, the performance of the two models is exactly the same, and there is no difference in use.
Fully compatible with SLE4442 chip is FM4442, FM4442 chip performance, use, use method is exactly the same as SLE4442, but because SLE4442 is the original imported chip, there will be many additional costs such as tariffs, so the price is relatively high.
SLE4448 card and SLE5528 card
The SLE4428 card upgrade chip is the SLE5528 card, the difference between the two models is only in the production process and production cost, the SLE5528 production cost is much lower than the SLE4428. For the user, the performance of the two models is exactly the same, and there is no difference in use.
Fully compatible with SLE4428 chip is FM4428, FM4428 chip performance, use, use method is exactly the same as SLE4428, but because SLE4428 is the original imported chip, there will be many additional costs such as tariffs, so the price is relatively high.
Key Differences between SLE4442 card, SLE5542 card, SLE4448 card and SLE5528 card
- Memory Size
- SLE4442/SLE5542: 256 bytes of memory.
- SLE4428/SLE5528: 1 KB of memory, suitable for applications requiring more storage.
