The ACR350 Secure Validator is an advanced version of ACR330 Validator. It is designed specifically for Automatic Fare Collection (AFC) systems to offer the convenience of cashless and secure payment in buses, ferries, trams, railways and other transportation modes. 

This validator enables high-speed transaction processing through 13.56 MHz contactless (RFID) technology. It supports ISO 14443 Type A and B cards, MIFARE®, and FeliCa. Being certified with PCI PTS 5.1 with SRED, major payment standards such as PBOC Level 1 (Contactless) and EMV™ Levels 1 and 2 (Contactless) including MasterCard® Contactless and Visa PayWave®, this Validator offers flexibility and security to open-loop payment systems. The embedded barcode scanner enables transactions through the use of print or mobile barcodes or other QR payment applications. 

It has advanced wireless connectivity options for data transfer such as GSM/GPRS, 3G/4G, and Wi-Fi.  With an optional GNSS feature, it can be used to locate vehicles, manage fleets and set flexible distance-based fares. Protecting the bus validator from harsh environments is its IK08 rating for mechanical impact, IP65 rating for dust and water protection and the additional Military Standard MIL-STD-810 for Shock and Vibration.

Control Signals, Ignition sense and Bluetooth 5.1 are featured in this brand-new validator. With these new features, ACR350 could be a perfect choice for transit operators.
