Frequently Asked Questions
Q: What standard do these NFC coin tags comply with?
A: These coin tags are fully compliant with ISO/IEC 15693, a widely adopted international standard for vicinity contactless smart cards operating at 13.56 MHz. This ensures broad compatibility with ISO15693-capable readers used in access control, inventory, and library systems.
Q: Are these SL2ICS20 coin tags rewritable?
A: Yes, the SL2ICS20-based PVC coin tags are rewritable. Their write distance is equal to their read distance (2–10 cm), and the EEPROM memory retains data for up to 10 years, making them reliable for long-term applications.
Q: Do I need a battery to power these coin tags?
A: No battery is required. These tags use contactless energy transfer — they draw power directly from the reader's antenna field, making them maintenance-free and ideal for embedded or hard-to-access applications.
Q: How many tags come in each pack?
A: Each order includes 100 PCS of 25mm SL2ICS20 PVC coin tags, making this pack a cost-effective solution for bulk deployments across retail, industrial, and institutional environments.
