JLTRFID TK4100 Card Features
Before purchasing a TK4100 card, it is important to understand what it can do and how it works in real life.

Our TK4100 cards are compatible with lots of EM4100 readers that operate at 125KHz. So, they’re great if you need replacement cards or extra cards for your current access control system.

The card doesn’t have a battery. When you approach it to the reader, it is activated.

JLTRFID TK4100 card operates at 125KHz, which is common in access control and ID systems. This frequency is commonly used for such applications.

This TK4100 ISO card is approximately 85.6 × 54 mm, easy to carry, print, and issue, like a normal credit card.

Most of them are PVC and are smooth and light. They are ideal for daily use in offices, schools, apartments, and for membership systems.

TK4100 Compatibility Guide
JLTRFID TK4100 card is compatible with 125KHz EM proximity systems and is compatible with many common access control readers. However, it will not work with all RFID systems. Your reader needs to use the same frequency and format; otherwise, the card might not work.
This is important to check first. Even if the card is flawless, it may not work with your system if the chip or frequency is incorrect. For instance, a TK4100 card won’t work with a 13.56MHz MIFARE reader. This will prevent you from delays, card registration issues, and additional expenses.

How to Choose the Right TK4100 Card for Your Access Control
When picking a TK4100 card, consider how you’ll use it and what materials and features you need.
PVC works well for regular stuff like access cards, staff IDs, and membership cards.
PET lasts longer for rougher use, whereas composite material is best for durable cards, like clamshell cards.
If you plan to print at your place, get blank cards; otherwise, opt for custom-printed ones which have logos, UID numbers, barcodes, QR codes, and other user info. Since the TK4100 is read-only, ensure you really need that UID printed on the card.
Also, choose JLTRFID for sample requests, help with compatibility, special order options, large orders, and keeping a steady supply.
