If you are taking photos and completing sessions with the Reader showing Pics and ID count acting as normal, but the Sync number on the Reader keeps increasing instead of going down:
The simplest answer to this is: that's because the images aren't able to upload right now. It might be that you are in spot with bad cellular reception and simply need to move to better reception, or you may have configured the device so that it can't upload via it's normal methods. Either way, you can continue shooting the event as normal and your Walker will keep recognising and storing images until it is able to upload.
*No matter which upload setting is selected, Walker will try to upload thumbnail images which will act as place holders until the fullsize images are uploaded.
If you want to resume uploading the full images from where you are, you'll need to check these things:
- What file size are you shooting?
- Image upload method
- Improve cellular reception
If you are shooting very large files, it will take longer to upload each file so this can cause a backlog when combined with poor signal. Remember to always shoot on the smallest file size you can - it will extend the battery life of your Walker and also save you money on uploads.

Image Upload Method
Check your "Image Upload Method" under Device settings on the Device page. It will be one of these three:
Do not upload
If you selected 'do not upload' on purpose, there is no problem right now. The sync number will continue increasing as you work, and it will only go down once you've enabled cellular or WiFi uploads again and the images are uploading. If this isn't what you intended, then change the setting to one of the other upload methods.
Cellular & WiFi Uploads
If you have Cellular + WiFi already selected, it may be that the Walker doesn’t have enough cellular reception to upload the images as fast as you are taking them.
If your Walker has insufficient signal to upload full sized images, it is ok to continue shooting and scanning as per normal, just tell people that their images will all upload when Walker has better signal strength.
See below for tips on how to improve cellular reception.
If signal strength is simply not usable at the venue, you could try uploading via onsite WiFi (just make sure you pre-configure the network name and password) or if there is no usable WiFi you can turn off cellular uploads to save battery. After the event turn uploads back on, and let the Walker upload during your commute back home - as soon as you leave the bad signal area, all the images will upload as fast as they can.
*People may say that their phone is still working so Walker should be able to upload all the images over the same connection… They may still be receiving txt messages and phone calls in your location, but that only uses a tiny amount of data compared to trying to upload large image files. Just because there is some phone reception, doesn’t guarantee that it will be fast enough for constant large file uploads.
WiFi Uploads only
WiFi only upload method means that images will only upload via the WiFi connection which you have configured for the device. If your device is set to "WiFi only" Image Upload Method on purpose, and the images are still not uploading: double check that you've enabled WiFi and the WiFi network name and password are correct.
If you're connected to WiFi and the images still aren't uploading, try moving closer to the WiFi source for better signal.

Improve cellular reception/signal
You can view the Walker's signal strength on the Reader screen. Remember that different carriers have different signal strengths in different places so you might need to adjust for the carrier displayed on the Walker screen.
Move to a location with better mobile reception and allow your Walker another 30 seconds to try uploading. Sometimes one corner of the room will be completely dead while the opposite corner of the same room has strong signal. If you find a spot which works well, try to stay in that area or at least return to that area regularly so that images can upload.
Find some space. Cellular congestion is a real thing - think of it a traffic jam on the airwaves, or a room full of phones which are trying to shout over the top of each other. If you can find a space which is less crowded, you might have better luck uploading.
If all else fails:
