Just got my Autosweep RFID at Shell Magallanes. No queue, maybe its a "long" weekend. It took 10 minutes. Just remember to print and fill-out the forms before going there.
Next is EasyTrip RFID, although I only go up north thrice a year.
If your nearer south of Manila, sa Coastal road may installation station.
Easy trip mas madali installation. Photocopy lang ng OR/CR and form. Wala na tanong tanong. Just pay minimum load. 400 ata yun.
