Step 1 · Tap & pay
Pick a pack. Pay by QR.
Tap the pack you want on the touchscreen, then scan the code with your phone. Here it's slot 18: M6A 30th Celebration, RM 49.99.
Step 2 · The order
The screen sends the order down a cable.
The touchscreen can't move anything itself. It sends a short coded message to the drive board inside the cabinet: turn slot 18.
Step 3 · One turn
The coil turns once.
Every slot is a spiral coil with one pack standing in each turn. One full turn moves every pack forward a place, and the front one goes over the edge.
Step 4 · The drop
It falls through a curtain of light.
The pack drops down behind the glass and through the beams of a light curtain into the pickup area. Breaking those beams is how the machine knows your pack really fell.
Step 5 · Confirmed
The board reports back.
The drive board tells the screen the pack was delivered, and the screen says so.
Step 6 · Collect
Push the flap. It's yours.
Reach in through the COLLECT flap at the bottom and take your pack.
