Does Google Wallet need wifi?

This thought just occured to me. If i go to a store or im in a cab and use the nfc, i know it will pick it up, but doesnt it need internet to communicate to google servers in order to do the transfer? its a wifi only device and yes i know you can tether, but just seems weird.

I don't have personal experience in this matter but I have read you only need wifi to setup the Wallet. Once the setup is complete, you can use it without wifi.

Unless I am mistaken it stores the information that would be normally stored on a physical card on your device so that it doesn't need a connection. When you go to make a purchase it then uses the nfc to transmit the data in someway, "swiping" the card.
But I'm not exactly sure. It makes the most sense to do it that way though.

the few times i have used wallet on my phone it seems to go out on the network to update the balance. I assume it works like a credit card though and the machine you tap your phone to does the credit check to the account so i would guess is not necessary. I'd try it Monday but I'll probably forget. We have vending machines at work with paypass terminals.

Hello!
After confirming from google, the Wallet app doesn't need WiFi or any data connection to pay at a paypass location since all it does is send card info over NFC. However, it does need wifi to update your balance and transaction list.

Used it today at cvs, does not need wifi

Mobile photography

I'm trying to set up my Samsung Galaxy S2 phone plus my Nexus 7 tablet so that I can copy the photos I've taken during the day with the S2 onto the N7 and process them on the tablet prior to uploading them to various online services.
I tried copying 58 files via Bluetooth today using ES File Manager. It took about an hour and a half and used a fair portion of my batteries. It didn't leave a lot of time for actually doing any processing.
In a place where public WiFi was accessible, albeit slow, I tried using AirDroid but the AP wouldn't let me log on twice using the same user name on two separate devices and, if it had, I doubt that it would allow peer-to-peer software for obvious security reasons.
I could upload the 58 files to Dropbox or Google Drive but that would involve twice the data transfer and the public WiFi seems to be even slower than Bluetooth. That many files would also hit my phone's data allowance pretty hard.
The Galaxy S2 can take a USB-OTG cable so I could transfer the
photos onto, say, an SD card. But to copy them onto the tablet I'd have to root it to get USB-OTG working. And that would mean wiping my apps and data.
I'll root the N7 eventually but, in the mean time, does anyone have an alternative solution that's relatively inexpensive? By which I mean not, for example, having to shell out for, and carry around, a wireless drive.

Hey Garry! ...I'm one of your Flickr contacts (Michael). I picked up a Nexus 7 this Friday, and intend to use it with my HTC One X phone. I will be experimenting with this too, and will let you know if I find anything. I tried Photo Transfer App, but it locked up after 15 photos, and that was on a really good wifi network. So far, Dropbox is my best option.

Hi, Michael
The problem with Dropbox is that you have to upload the photos then download them again, which would eat heavily into my data plan, not to mention the time it would take.
Someone mentioned an app called Bump which I'm going to try out but I expect it will be as slow as using Bluetooth.
Whatever I find, I'll post back here.

The other apps I'll be looking at when I get time are Nexus Photo viewer and Nexus Media Importer, both of which are being developed by an XDA from member. Hmmm... when I get time...

My current set up is with +google instant upload. Photos taken are uploaded on the fly to my picasa account. I have an all you can eat data plan so I'm not that worried about usage however I generally have this set to wifi only. I find any time I want to mess around with my pics they will be there on the N7.
I never really have a need to edit something immediately.
I do have a problem trying to find files I've edited on my phone as they don't sync to the tablet.

3G N7 as phone

Anyone know if it's likely the 3G N7 will work as a phone when connected to a Bluetooth headset? I don't think other 3G tablets (Android or IOS) have this functionality enabled, do they?

I'm not sure on your question specifically. However, I wonder if the 3G will support the use of VoIP technology so you can use something like GrooveIP lite (via google voice) to make phone calls (as many do over WIFI) - the only problem being that it's not the most efficient use of bandwidth/min of talk time.

I dare say the 3G connection would support it so long as VoIP is allowed by your carrier.
I was thinking more of using it as a GSM phone replacement. If I have my N7 with me anyway, I could use something like this maybe as the 'handset'

Short answer is probably no.
Look up tablet talk on the play store though, as long as your phone is in your bag/pocket you could use that to do what you're talking about

Calls on HTC Flyer works. So maybe some devs will implement this feature...

I have TabletTalk. It's good for what it does, but I'm wondering if I can go forwards with essentially one device with 1 SIM (plus headset) not a tablet + phone.
I suppose I could "emulate" what I want with a small phone tethered to a WiFi N7 with WiFi, plus TabletTalk. But the phone will be running WiFi hotspot mode on all the time and battery life will be awful on it, right? Better to be able to use the tablet as a rather large phone and a bluetooth headset connected to it for calls. This scenario will also be a mess when I move to an area with it's own WiFi, as I don't think I can have the tablet connected to another WiFi connection at the same time as the phone. And I can connect the phone using Bluetooth for TabletTalk, but I can't use the Bluetooth connection effectively for tethering to the phone for data.

Well, I guess there's a chance it will anyway on the N7, but you'd have thought it would have been a promoted feature if it was going to be possible out of the box...

Wi-Fi Direct with Beam

So I've really been enjoying my new nexus 4. But I've if the things that's bothered me the most is the poor implementation of beaming. For example when I try to beam a 30 second HD video I recorded on my nexus onto my brother's identical nexus 4, it starts up a Bluetooth connection. Am I missing something? I thought it was supposed to create a Wi-Fi direct connection between the two, which would been much much faster.

I tried for several hours last night trying to get wifi direct to work between my Nexus 4 and Nexus 10 and nothing seemed to work. I then found this app and it worked like a champ:

Bumping this.
How exactly do I use that app.. is it a necessity that both phones have to have the same app running? could someone please run me through the process? I need to transfer 100 mb files between my n4 and the gnex.

Took me a while but I finally got it too work. After adding the viewing device to the network I rebooted the source device (nexus 4). I was then able to see the target device from my Nexus 4. Then you send an invite from the nexus 4 to the source device. Accept and once connected you are golden. YouTube app ob nexus 4 actually then asks which device should display the video. I was also able to share media using BubbleUPnP. Hope that helps someone

You need to install Wi-Fi Direct on both devices. Make sure both have NFC on.
You can approach the problem in 2 ways (really only 1):
1) Link both phones to each other by directly accessing the app from the drawer first. Once a connection has been established, use your file explorer to locate the file (I use ES File Explorer) and long press it. You'll get a dialog box. Locate "Share" and then click on "Wi-Fi Direct". You'll notice it's sending when you see the Wi-Fi Direct icon in the notification bar.
2) The process is the reverse of 1; locate the file, long press and then Share > Wi-Fi Direct. It'll prompt you to establish a connection.
Speeds I've seen at most is 39Mbit between my GS3 and N4.
Be aware, certain devices don't like to accept invites. In this case it'll error out or not communicate with the other device. Send the invite from the other device instead. If it reaches this situation, the program may be buggy (both refuse to communicate with each other) until you force close the app using a task manager and disable/re-enable NFC.
An example...my GS3 doesn't like to accept invites from the N4 so I'm forced to send invites from the GS3 to the N4 instead.

Android Beaming is typically done using Bluetooth (for small files like pictures), hence why you see the Bluetooth icon pop up. I've sent files between my phones and thought it wasn't sending files. It's just ridiculously slow as is the nature of Bluetooth. Random tidbit here -- Samsung implemented their own Android Beaming protocol (S-Beam) to use Wi-Fi Direct instead of the Bluetooth connection.

Thanks a lot man! Got it working.. although having an app for it is still sort of clumsy. Wonder when google will finish up what is incomplete

[Q] SPH-L720 Hotspot

Hello,
I often find myself in my car pretending my phone is a laptop while my laptop sits right next to me in a brief case. I thought well wouldnt it be nice if I could use my laptop to do work in my car rather than my cellphone.
In my city I have 4G all the time with this sprint service, which would be great if I could just get my laptop connected to it. My phone is rooted and I have a screen shot of the "about device" section under the more tab in settings. It also runs a .odex file system which a google search on another site said was important.
Could someone tell me how I could connect my computer to my SG4S to utilize the 4G internet. All my google searches have lead me to this forum for expert advice.
Many Thanks.

Bump

Have a look at this thread. Download the app and follow direction. This app works on our GS4 though it's in the Note 3 section. http://forum.xda-developers.com/note-3-sprint/themes-apps/app-one-click-hotspot-enabler-menus-t2816159
I do see you're on the MF9 firmware. You may need to be on the current NG2 4.4.2 for this to work.
