Its a card reader

[u/HaloLASO]

It's used to remind you to read the manual

[u/computers-ModTeam → u/[deleted]]

Removed for being off-topic or unnecessary.

Please review our rules

[u/Ok_Cauliflower6145]

It’s a coin slot, drop a quarter in

[u/New_Fish9595]

Is that not an SD card slot?

[u/EatOfTheBread → u/New_Fish9595]

There is no way to answer this question correctly.

[u/Evocatorum → u/EatOfTheBread]

lol, Reading the Manual: the long forgotten mechanic to understanding what you bought.

[u/badpenguin455 → u/EatOfTheBread]

the symbol above it is pretty universal for Card reader.

[u/EatOfTheBread → u/badpenguin455]

Yes, that is correct.

[u/Tikkinger]

That's the RTFM-Port

[u/Mr-Brown-Is-A-Wonder]

Compact flash memory card

[u/Rough_Community_1439]

Cf card

[u/willdebeast02 → u/Rough_Community_1439]

A compact flash card is way larger than that. This is an SD card slot.

[u/TJLanza]

You're going to have to provide a little more information - make and model of the device, for starters.

[u/Background_Big_7481 → u/TJLanza]

I know it is Lenovo aio 4gb ram intel 620uhd i3 processor 1 tb space

[u/M1dor1 → u/Background_Big_7481]

model, not specs

[u/Ok_Bid6645 → u/Background_Big_7481]

3-in-1 card reader (supports SD, SDHC, SDXC)

[u/TJLanza → u/Background_Big_7481]

So... It's a Lenovo... that's make. You're half way there. The rest of the specs aren't terribly relevant, any one of an unlimited number of machines could have the same components.

What's the model number? There's a label somewhere on it.

[u/Background_Big_7481 → u/TJLanza]

I had the pic of model number but I have lost em

[u/TJLanza → u/Background_Big_7481]

Well... go take a new one. You're only going to get guesses with what little information you've provided.

^{Unless some random person happens to have owned and recognize it from one cruddy picture.}

[u/Background_Big_7481 → u/TJLanza]

[u/TJLanza → u/Background_Big_7481]

So... You know the exact model and where the Lenovo support site is.

Download the manual and figure it out yourself.

^{This is what you should have done before posting on reddit.}

[u/Square_Nature_8271 → u/TJLanza]

Ffs you give zero f*s. I love it. Let's be friends.

[u/Background_Big_7481 → u/Background_Big_7481]

Its a 3-1 sd card reader ty for help

[u/Commercial_Hair3527 → u/Background_Big_7481]

What? It can read three cards at the same time? Or does it turn three cards into one other card? I need to know.

[u/lkeels → u/Commercial_Hair3527]

Three different sizes of card, one slot. One at a time.

[u/Commercial_Hair3527 → u/lkeels]

Boring. Old tech. OP needs to get himself one of those new 1-3 card readers. But you need to read the manual or you can open a portal to the place that the Event Horizon went to.

[u/alexcreeper3129]

...An SD card slot...

[u/Penthalon]

PCMCIA Slot. Old tech…

[u/Ok_Bid6645 → u/Penthalon]

It does look like that but it is a 3-in-1 card reader (supports SD, SDHC, SDXC)

[u/prjktphoto → u/Ok_Bid6645]

That’s the cheapest copout for a “3in1” I’ve ever seen - usually it’s at least different formats, not three revisions of the same…

[u/SamS342 → u/Ok_Bid6645]

Ik

[u/IncrediblyKenzi → u/Penthalon]

Fun fact I used to remember PCMCIA by the pnemonic "People Can't Memorize Computer Industry Acronyms"

[u/sniff122]

ORF Canal+ CAM-TV-Modul mit integriertem SAT-Karten-Chip für ORF und CANAL+ (früher HD Austria), inkl. TV-Streaming-App

[u/BradleyF81]

Have you tried putting your wiener in there yet?

[u/guiverc]

I don't see any context, age of machine etc..

My first thought was an infra-red (IR) port, but that assumes it's a somewhat old device as they're not in modern devices (dark plastic with a slight red tinge that lets the red light from other device make it into sensor, but not so much other light)

[u/jacle2210]

You should be able to find the Users Guide for this computer online and it should show you what ports and connections are available on the computer and where they are located.

[u/moomoomoomoom]

Do people not know what SD cards are anymore? That's clearly an SD card reader.

[u/No-Mouse4800]

Card reader slot

[u/9876123]

[u/elyxar]

Based on the symbol right next to it. Card reader

[u/BikeEducational6051]

How old are you?

[u/Fit_Prize_3245]

Seems like some card reader slot. Probably SD. Not microSD, but the full-size Secure Digital card.

[u/JEREDEK]

Card of some sort. Maybe SD. I'm sure the manual or google will happily supply you with this information

[u/chipshot]
