The fi.d.o self-service pet tag engraving kiosk in Carlsbad's La Costa Petco at 3421 Via Montebello produces custom-engraved identification tags on demand using a touchscreen interface. The kiosk shares floor space with Petco Grooming in the La Costa store, allowing owners to replace worn collar tags while their pet is on-site for a grooming appointment—eliminating a separate trip for ID updates. The station engraves stainless steel and aluminum blanks in multiple shapes—bone, circle, heart, and hydrant—with up to four lines of custom text including the pet's name, owner phone number, and address. Daycare enrollment at Hot Dog On A Leash mandates a legible collar tag or microchip number for every dog, making the fi.d.o kiosk a practical same-day stop before a first drop-off. The diamond-drag engraving mechanism scores text into the metal substrate rather than printing it, producing character depth that withstands saltwater exposure along the Carlsbad coastline.
