9651T vs. 9691T — Single-Tech vs. Multi-Tech
Schlage offers two closely-related smart keyfobs in this product line. The difference is single-technology vs. multi-technology:
| Feature | 9651T (this page) | 9691T |
|---|---|---|
| Technology | Single — 13.56 MHz only | Multi — 125 kHz proximity + 13.56 MHz |
| MIFARE chip | MIFARE Classic 1K | MIFARE Classic 1K |
| Memory | 1K byte / 8K bit | 1K byte / 8K bit |
| Best fit | Properties standardized on 13.56 MHz only | Properties undergoing phased migration from 125 kHz Prox |
| Cost | Lower | Higher |
Choose 9651T when the property has already standardized on 13.56 MHz Schlage / aptiQ readers and there is no legacy Prox population to support. Choose 9691T when the property still has Prox readers in service and the keyfob must work on both reader generations during the phased migration.
