The Compass Card was an orange or yellow, credit-card-sized contactless smartcard which held a transit pass. The Compass Card card must be tapped on electronic readers when entering and transferring within the system in order to validate it. Compass Card readers were integrated in bus fareboxes and standalone readers are located just outside the paid area of rail stations. Because the San Diego Trolley, Coaster and Sprinter operate on a proof-of-payment system, fare inspectors randomly checked to make sure Compass Card users have validated their cards by using a wireless handheld unit. The cards were "recharged" in person from TVMs in rail stations, at MTS or NCTD Transit Offices, at Albertsons stores, or online. The card is designed to reduce the number of transactions at customer service centers.
Initially the San Diego Association of Governments only offered monthly passes on the compass card system-wide, and 14-day passes via telephone. Stored cash value cards were introduced in 2017,[2] with plans in the future capable of automatically purchasing a day pass on the first tap.
Capabilities
Customers are able to perform the following transactions at the corresponding locations with a Compass Card as indicated below:
Select San Diego county Albertsons and check cashing locations
and Transit Center "MTS Station Shops"
Implementation
The following process took place when a user tapped their card on a reader:
Authenticates the microchip's serial number
(to avoid counterfeited or stolen cards)
Reads the rider's balance and/or passes, and displays the results
Reports the rider's activity to the Compass Card server
(rail validators synchronize data immediately, bus validators have a 12- to 24-hour delay)
Writes the new balance and/or passes
(if applicable)
The next behavior depended on the reader:
Displays a Thank You message along with a small green light for on-platform readers such as the Coaster, Sprinter, and San Diego Trolley.
Shows green light and beeps once if Compass Card has valid fare, or shows a red light with an error message and beeps three times if the card is not valid or a read error occurs, for readers installed next to fareboxes. For passes, the expiration date of the pass is also displayed when the green light is lit and the reader beeps once.
Beeps once if the Compass card has valid fare, or beeps three times if the card is not valid or a read error occurs, for readers integrated into the farebox. For passes, the expiration date of the pass is also displayed shortly after the reader beeps once.
The driver's side computer will also show OK for a successful pass read. A type of frequency shift-keying that sounds different from the standard confirmation beep will occur for Youth or Senior/Disabled/Medicare passes that are valid, and the driver's side computer will show YTH for the Youth pass or SDM for the Senior/Disabled/Medicare pass.
Read errors that were displayed on the reader screen included, but not limited to:
Invalid CRC.
Invalid Card, can occur the first time on some readers even with a valid card, but if the card is valid a second attempt will register correctly. (The driver's side computer will show as NV for an invalid card error).
Operation Failed, if an add value was initiated from the farebox computer but did not work.
Read Error. (Seems to occur only on some readers integrated into the farebox, and turning the card sideways when tapping may work around this problem).
Feedback used too soon. (The driver's side computer will show as FBK for a feedback related error).
Already Touched.
