Card Reader For Android

[Trinh Livingston]

Rightnow I am having Tablet having OS Android 2.3.3 instead of NFC phone,so I need to connect External card reader to tablet.Please tell me which card reader should I prefer and any driver needed to connect card reader to tablet.The inbuilt NFC libraries support to that reader or not?thanks in advance.

I found an answer,the ACS now provides android library and sample application for their readers.You can find library here and some information and video demo of android supported readers is here.

The built-in NFC library in Android 2.3 and 4.0 only supports the PN544 NFC chip by NXP Semiconductors. I don't think there are any card readers on the market that use it, as this chip is specifically designed for use in mobile devices. You may be able to find alternative implementations of the Android NFC API that support other NFC chips, though.

Another issue may be that your tablet most likely does not have the required NFC libraries installed, including the required system service (NfcManager). After all, your tablet has no NFC support, so it does not need these software components. So a new ROM system image would have to be created for your tablet that includes these software components.

Taking one of the many common desktop readers is probably not really feasible. Creating all the necessary software to integrate it into Android is not really a trivial task. It may be easier to just buy an Android phone with NFC or wait if an Android tablet with NFC comes out.

When a manufacturer launch a new phone with a different NFC chip is because someone have created the drivers to use such chips and interface with Android's NFC classes, specifically the NfcManager class and the NfcAdapter class wich represents the local NFC adapter.

Best case scenario, you could use the Android NDK to create low level C/C++ classes to communicate somehow the External NFC Card reader with Android and then make more custom programming with the NDK to make the NfcAdapter on the SDK to detect it... and there are no warranties that you'll succeed.

And... if you are thinking about going to and import a tablet with NFC reader, think twice, because that ones might not allow you to do all what the NXP Semiconductors chip does with Android Beam (TM) such as Read/Write and support different I/O operations with NFC-A, B, F, V or ISO-DEP.

For your time's sake (and because time is the most valuable asset for anyone these days). I think your best option is to get a couple of NFC Phones such as the Galaxy Nexus S, DROID Razr, Xperia S, HTC Incredible, etc... those will work right out of the box, that's what we are doing.

Hey sachin, Since your device doesn't have NFC, it won't have the NFC radio and hence it can not connect (Read or write) to an NFC card. According to the NFC lib, when ever you try to get NFCAdapter it will always return null.so you atleast need an nfc enabled android device for any experiment.

In my project, we used ACR122 smart card reader that will be connect to a pc not android device.This reader is used to read any nfc tag. An nfc enabled android device will act as a nfc tag in card emulation mode.

Here can you find the documentation for the libraries and example code. However it doesn't seem to have an option to write data. If you want to write to your NFC reader use the transmit function to send byte arrays.

This is a good topic. I echo RacZo's concerns about NFC library support in the Alibaba sourced tablets. Since NFC chipsets in devices vary and some have dubious or no support for certain operations, you need to be careful and test out your app on those beforehand.

The ACS reader can be a cost effective solution, and there are some mature and well supported libraries and SDKs that support its integration with Android. The downside of the ACS external reader is battery life. Because it monopolizes the the USB port, and Android tablets won't allow charging through a USB port while a peripheral is connected to it. So if your application is some kind of kiosk or self serve app, this may be a problem.

However as a developer of an NFC app, you really do not want the same functionality from the external service as the built-in. The external reader probably has more functionality and at a very minimum you want to know whether the reader is plugged in or not.

No for the mp3. Those have to be put into iTunes on the computer to sync to the phone. I'm not sure what an apks wallpaper is, but you can move photos, using the SD card reader for the iPhone, and you can use photos for wallpaper on the iPhone.

Thanks. I've not much of a clue about Android. I've got a niece that has one and she has only had problems through several versions of software and hardware. She is ready to go for the iPhone, since my family and I don't have any problems with ours.

i don't know reason why i no longer see clean now button in storage that should come up when device mainteance is 97 or below on 95 haven't seen since in addition unnecessary data isn't showing at top in storage along with system user data available space

i'm conflicted because few times samsung chat like this past sun telling me yes nothing that i did, i'm a hurting need that clean now button back from tues night just watching that available space every day go down nothing to do about it

seems i'm forced into getting a new phone christmas due to what samsung prob done remove clean now button storage and i don't want to go every app that i have clear data that's nonesense and waste of time

i thought maybe iphone since everybody in family has it and i do already have apple account for my apple tv 4k but not sure since cannot do mp3's from s7 phone to iphone i used mostly mp3 ringstones btw

so not sure what to do if i get another samsung device i need to make sure that both storage button is still there device mainteance as well as unncessary data don't want to be in this same position that i'll been currently in since last weds

Hey, I appreciate this has been asked before, but I was looking for up to date advice on which card reader to purchase for use with Shopify POS. The one recommended by Shopify, the Wisepad 3 Reader, only appears compatible with Apple hardware, which I don't have and would rather avoid. Is it also compatible with Android phones, and if not, which other readers are compatible with Shopify POS and recommended?

I took some time to check out the UK store and did see that there is only one reader currently available there, and it's not clear if it's compatible with android or not. I reached out to our Retail Support Team and can confirm that the reader available in the UK store is NOT compatible with android, and must be used with an iOS device.

I spoke to the team about some alternatives we may be able to advise on in this situation. Our team strongly recommends that if you're using Shopify POS, that you're operating it off of an iOS system, as Shopfy POS was built with iOS functionality in mind. They advised looking for a cheap iPad that's available to run your POS system if using Shopify Payments.

I also asked about third party readers that may be compatible with android. The team let me know that were are some 3rd party readers you could look into, but they would need to be set up on a third party payment provider, and then a custom payment option would have to be entered into your POS app. This means that your workflow would look as follows:

I'd love to spend some time chatting with you regarding this! First, do you mind sharing with me what Shopify Hardware store you're looking to order from? We are having some availability constraints due to supply shortages globally, so pinpointing what regional store you're looking to order from, or the location of which you operate, will help me get you some information on available hardware.

I can't agree that this is an accepted solution - nothing raised in the original problem has actually been solved. The recommendation as given was to purchase brand new hardware, or to process every order as a 'cash sale'. From an accounting perspective, nothing would link the payment shown in Xero or Quickbooks etc, to the Shopify order, and these would have to be manually reconciled. For a few large orders per month, this could work. For retail outlets, or food and drink outlets, this would be a nightmare given the volume of orders we receive.
