[TIP] EE apps – Cash on Tap and Tap Wallet – NFC payments – Advice and installing on
Ignore this post if you’re not on EE (a UK network).
Though not widely advertised, Cash on Tap, (EE’s NFC payment app) does work on the Xperia SP (the EE website is ambiguous – in places it says the SP can use the service, but on the device compatibility web page the SP is not listed).
It’s a decent service and perhaps more reassuring than contactless payment cards because you top it up with how much you want, rather than it having direct access to your bank account/credit card balance. It can also be used as a virtual payment card – so if you’re ordering online from a website you’re unsure about and don’t want to give them your normal credit/debit card you can use the details on the virtual card. If it’s a dodgy website and they try and take more money, the most they can steal is the balance of your ‘tap wallet’.
More good news is that they give you £5 just for installing the app and a further £5 when you add money to the service – so yes, you get given £10 for doing next to nothing and who can argue with free money?
I bought my lunch using my phone yesterday, which whilst a bit geeky, did make me feel kind of cool (I know that in other parts of the world NFC payments are used a lot more, but it’s not common in the UK). I felt at the forefront of technology for once.
Anyway, what is evident is that for security purposes, to start using this service your device has to be authenticated by EE - you download a bridging app (cash on tap), then EE check your credentials (which can take two hours) and once this is done you are allowed to download the ‘tap wallet’ which is the app which actually allows you to make NFC payments.
Unfortunately part of this process involves validating the firmware of your phone and you simply won’t be allowed to install this service if you are using a custom rom.
However, if you install both parts on stock, set up your account etc. and make a CWM backup you can use Nandroid manager to restore the apps and data to a custom ROM (I guess this will work with Titanium too?) and the service will work perfectly, though I suspect if they update either app you will lose the service and have to do everything again.
EDIT: Also, you need an NFC enabled SIM from EE for this to work. Check your SIM card, if it has an N after the string of numbers it is the correct type, otherwise you'll have to get one from EE.
