1.0. Introduction ACR321 – Ticket Validator is designed specifically for the use in Automatic Fare Collection (AFC) systems for public transport, e.g. for buses, ferries, trams, railway and other transportation means. ACR321 supports all smart cards/tags compliant to ISO14443 Type A & B, Mifare, and Near Field Communication (NFC) standard. By virtue of the embedded powerful 32bit ARM 11 processor, ACR321 enables a high speed transaction processing and transaction records collection.

3.0. Illustration 3.1. ACR321 device and parts The main components on the front side of the ACR320 are shown below: Page 5 of 11 ACR321 - User Manual Document VersionTitle 1.00 Here Document Title Here info@acs.com.hk www.acs.com.
3.2. Battery A rechargeable Li-ion battery supplies energy to the device once the external power source cannot supply power to the device. So, transactions can still be processed even the power supply of the bus is out of order. The battery locates at back of the device. In order to change the battery, turn the screw in the circle in the figure below to left to remove the battery cover. Follow the direction of the red arrow to take away the cover.
3.3. SAM card slots There are 4 SAM card holders on ACR320. Each holder can contain 1 SAM card, so ACR320 has 4 SAM card slots in total. They are located behind the battery. In order to insert or change SAM cards, please follow some simple steps below. 1. Follow the instruction in chapter 3.2 to remove the battery cover 2. Unplug and remove the Li-ion battery and the SAM card slots will be seen Page 7 of 11 ACR321 - User Manual Document VersionTitle 1.00 Here Document Title Here info@acs.com.hk www.
