An integrated reader combines the reader electronics and antenna into a single enclosure. No external antenna is required. This simplifies installation, reduces cabling, and lowers total cost of ownership — ideal for parking gates, garbage trucks, and outdoor portals. A fixed multi-port reader, on the other hand, connects to external antennas via multiple RF ports (4 or 8 ports). This allows flexible antenna placement for large coverage areas such as warehouse dock doors, production lines, and ETC lanes. The choice depends on your deployment: integrated for simplicity, multi-port for flexibility.
