Parking Pay Station Product

Overview

A parking pay station sells parking time at the curb or in a garage, replacing a row of single-space meters: one pillar serves 20–40 spaces. The machine takes coins, notes, and cards, prints a dashboard ticket or records the plate number against the payment, and reports everything to a back office over cellular. The architecture splits cleanly in two — a cash-handling and vault section engineered against theft, and a low-power electronics section engineered to run for years on a solar-charged battery.

Two operating models share the same hardware. Pay-and-display issues a printed ticket from the Ticket Printer that the driver places on the dashboard; pay-by-plate has the driver type the registration on the Metal Keypad, and enforcement checks plates against the payment database instead of looking through windshields. Pay-by-plate is displacing pay-and-display because it eliminates the walk back to the car and enables enforcement by camera car.

Cash path

Coins enter through the shuttered Coin Slot and fall through the Coin Validator, which measures each coin's diameter, thickness, and alloy signature with inductive Copper Winding coils as it rolls past. Accepted coins wait in the Coin Escrow; if the driver cancels, the escrow dumps to the Return Cup, and on a committed transaction the coins drop through the anti-fishing baffles of the Vault Chute into the vault. The Coin Gate solenoids do the steering.

Notes follow the same escrow logic. The lit Note Bezel accepts a note in any orientation, the Note Transport carries it past the Note Validator Head — a contact CMOS Image Sensor plus magnetic Hall Sensor heads reading optical, UV, and magnetic security features — and committed notes are packed by the Stacker Pusher into the locked Stacker Cassette, which holds 600–1,000 notes and swaps out sealed so collection crews never touch loose cash.

Card payment is the growth tender. The Chip Reader and NFC Antenna feed the Secure Payment Module, a PCI-PTS device that encrypts card data at the read head; authorization runs in real time over the LTE Modem. Many operators now deploy cashless-only variants, deleting the coin and note systems entirely and with them most of the theft surface and collection cost.

Power engineering

Curbside stations rarely get mains power, so the design is an exercise in energy budgeting. A 10–30 W Solar Panel on the pillar crown charges a 12 V deep-cycle 12 V Battery through the MPPT Charge Controller. The Main Control Board sleeps between transactions, waking on keypad or coin-slot activity; the transflective LCD Panel is readable by reflected sunlight and only the Backlight Module LED module costs power at night. The LTE modem batches its back-office sync except for card authorizations, which must be live. A healthy station survives weeks of overcast on battery alone; printing the ticket is by far the most expensive single operation in the budget.

Security

Cash attracts attack, and the pillar shows it. The Pillar Body is 3 mm galvanized steel with anti-drill plates over the locks; the vault occupies a separately welded Vault Strongbox in the base, behind a Vault Lock on a different key plan from the Service Door, so maintenance staff can change paper without any path to money. Coins land in a Coin Canister that self-seals on removal. Every vault opening trips the Collection Switch into the audit log, every door has an Alarm Switch reporting in real time, and the Foundation Cage — an anchor cage cast into the concrete base — defeats the simplest attack of all, pulling the whole pillar over and opening it elsewhere.

Back office and enforcement

The station is one node in a managed network. Over the modem it uploads transactions and cash levels, downloads tariff tables to the Main Control Board, and answers enforcement queries — for pay-by-plate, an officer's handheld or a camera car asks the back office whether a plate has time on it. Cash-level telemetry drives collection routing: crews visit machines when cassettes approach capacity rather than on a fixed schedule, which cuts both cost and the predictability that armed robbery planning depends on. Fault telemetry from the Paper Sensor and the validators feeds maintenance dispatch the same way.
