Counter card
Sits next to the point of sale where the customer is already standing. Big QR, one line of instruction, your shop name. This is the piece that does most of the work — the owner scans it while the advisor is still typing the ticket.
Printable check-in kit
A QR check-in sign, so the iPad never leaves the counter.
Four printable pieces: a counter card, a window or A-frame sign, a waiting-room table tent, and key tags. The owner scans, authorizes on their own phone, and your advisor keeps both hands on the ticket. Every GuestLot location can print the whole set, already carrying its own shop name and QR code.

Scan to start check-in on your phone. Access ends at pickup.
Why print anything
The counter is the bottleneck, not the software.
Check-in takes about two minutes, and most of that is one person reading a phone number aloud while another person types it. The QR path removes the reading-aloud part and the typo that follows it.
- The owner enters their own mobile number, so the receipt goes to the right phone.
- The authorization happens on the owner’s device, inside the Tesla app they already trust. Nobody is asked to log in on shop hardware.
- Drop-offs before you open still land inside a valid window instead of a gap in the record.
- A busy Saturday stops queueing behind one iPad and one advisor.
- No customer ever needs to hold your iPad, and no advisor types a stranger’s credentials.

Same custody window, same receipt, same record. Only the door changed.
What is in the kit
Four pieces, each for one spot in the shop.
Window or A-frame sign
For the door, the drop box, or an A-frame at the mouth of the lot. Aimed at after-hours and early drop-offs: the owner scans before they walk away, so the car is inside a valid custody window from the minute it hits your lot.
Table tent
For the waiting room, where a tint customer sits for two hours anyway. Fewer instructions, more reassurance — it points at the owner page that explains what the shop can and cannot see.
Key tag
Goes on the ring or in the pouch with the NFC card the owner left. Carries the VIN last six and the visit code so the card in your drawer is traceable to a ticket instead of being an anonymous plastic rectangle.
Printing and lamination
Print it at the shop or hand it to a print shop.
Everything is laid out for US letter and tabloid so a front-office printer can handle three of the four pieces. Only the A-frame sign really wants a print shop.
- Print at 100% scale, no fit-to-page. Scaling shrinks the QR quiet zone and slow phones start to struggle.
- Counter card and key tags: laminate them. They live in a shop where hands are covered in slip solution and adhesive remover.
- Use matte laminate, not gloss. Gloss under fluorescent light is the single most common reason a QR code will not scan.
- Mount the window sign at roughly eye height and keep the surrounding glass clear — phone cameras need about a fist of empty space around the code.
- Reprint after a rebrand or a location move. The code points at your location page, so an old sign from a closed address will not check anyone in.
The generator lives inside the app: sign in and open the print kit, pick your pieces, and it renders a PDF carrying your shop name and code. It is included on both plans — see pricing.
Pair it with
The owner’s page
Shops that text the owner page with the appointment reminder get fewer questions at the counter. It explains what authorizing grants, what you can see, and how to revoke — in the owner’s language, without a sales pitch.
Pair it with
Pre-authorization
The sign covers walk-ins. For booked appointments, pre-authorization sends the link the day before so access is already armed when the car pulls in. Both paths end in the same window and the same receipt — see how it works.
Questions
About the QR check-in sign
Does the owner need to download anything to scan the QR sign?
No. The camera app on any modern phone reads the code and opens a web page. From there the owner taps through to Tesla's own authorization screen, approves the window, and is done. There is no GuestLot app for owners at any point.
What is on the QR code?
A link to your location's check-in page. It is scoped to the shop, not to a specific car, so the same printed sign works for every customer every day. Nothing sensitive is encoded in the sign itself.
Do I still need the counter iPad?
You need something to run PorterKey on, but it never has to leave the counter and it never has to be handed to a customer. The QR path exists so the owner uses their own phone for the part that involves their own Tesla account.
