ST25TB04K cards are contactless RFID cards operating in HF at 13.56 MHz (carrier frequency) and 847 kHz (subcarrier frequency). They are designed in accordance with standard ISO 14443 B, with respect to parts 2 (for RF signal strength) and 3 (for anti-collision filtering). The anti-collision algorithm is particularly important because it allows tags present in the same magnetic field to be identified at the same time.
ST25TB04K RFID cards are designed for multiple applications, such as access control, attendance control, identification and as electronic wallets.
Finally, all ST25TB04K cards are available with dimensions 86 mm x 54 mm x 0.86 mm for PVC and PETG, and 86 mm x 54 mm x 1.3 mm for wood.
